The lifting lever is required for Air, Steam and Hot Water.ASME SEC VIII UG-136 (a) (3). The Plain or Open lever assembly isnot pressure-tight and may leak to the atmosphere. Typically used on airand steam applications. Packed levers ensure leakage does not occureither when the valve is open or when backpressure is present.Line 26 Test Gag - The test gag is used to prevent the safety valve from lifting.This is normally only specified for in-place testing of multiple steamvalve installations or where hydrotesting the system is required.Line 27 Vent with Bug Screen - Vents the Bonnet of the PZV.

If other, then enter n/a and goto Line 33.Line 33 Other - (Basis of Selection), Other than Line 32 worst case relief (e.g., - Thermal Relief, Exchanger Tube Failure, Loss of Reflux, Loss ofCooling Fans, etc.)Line 35 Process Fluid - (e.g., Hydrocarbon, Water, Gasoline, Oil, etc.)Line 36 Corrosive Compounds - Name any significant corrosive compoundssuch as H2S, Sour water, etc.Line 37 Required Capacity - This capacity is given at standard conditions. It is the maximum (worst case) relieving scenario for the basis of selection.Line 38 MW or SG @ Relieving Temperature - The molecular weight of thegas or vapor or the Specific Gravity (referenced to water). The specificgravity is stated at the flowing (relieving) conditions.Line 39 Viscosity @ Relieving Temperature in Centipoise.Line 40 Weight % Flashing / Molecular Weight of the VaporApplicable to liquids only. Flashing liquids require specialconsideration. The correct relief valve size lies between that obtainedfrom the liquid formula and that obtained from the vapor formula,usually closer to the liquid. Flashing probably occurs at the throat,where velocity is sonic. The most reasonable approach is to determineNext Planned Update: 17 July 2017 Pressure Relief Valve Conventional and Balanced Types the liquid portion and the vapor portion separately, compute the arearequired for each quantity, and add them together.Assume an isenthalpic (adiabatic) process.% Flashing = H1-H2 /H LVwhere:H1 = Enthalpy in BTU/lb of saturated liquid at upstream temperature.H2 = Enthalpy in BTU/lb of saturated liquid at downstream pressure.H LV = Latent Heat of Vaporization BTU/lb at downstream pressure.An alternative to the above is to use a process simulation package toperform the flash calculation. Saudi Aramco approved simulationpackages are HYSYS and Pro2 by Simulation Sciences.Balanced Bellows valves may be necessary as a safety precaution whenthe increased downstream PZV body pressure, due to flashing flowconditions, is excessive or cannot be predicted with certainty.Line 41 Temperature at Normal Conditions and at Relief.For Blocked discharge of liquids, the relief temperature is typically thenormal temperature. For blocked discharge of gas on the outlet of acompressor, consider the increased temperature due to the increasedrelieving pressure. For the fire case, the relief temperature of the vaporis the boiling point of the liquid at the relieving pressure.Line 42 Pressure at Normal Conditions and Design Pressure.Design Pressure refers to (at least) the most severe conditions ofcoincident temperature and pressure expected during operation.Design pressure is always equal to or less than the MAWP. Used todetermine the minimum permissible thickness or physical characteristicsof different parts of the vessel. Typically, a corrosion allowance is thenadded to the calculated thickness. If the MAWP is greater than thedesign pressure then this usually means the thickness calculated for thedesign pressure was not commercially available and the next largerrolled plate or pipe was used.Line 43 Set PressureThe set pressure for a single relief valve installation on a vessel orprotected vessel system may not exceed 100% of the MAWP.Next Planned Update: 17 July 2017 Pressure Relief Valve Conventional and Balanced Types Set pressure staggering is allowed for Multiple PZV installations as follows:- First Valve - The maximum allowable set pressure shall not exceed100% of the MAWP- Additional Valve(s) - Set pressures may be staggered but shall notexceed 105% of the MAWP.- Supplemental Valves - (For additional hazard created by exposure tofire or heat). The set pressure shall not exceed 110% of the MAWP.Set pressure shall not exceed 110% for thermal relief valves on piping.(SAES-L-140).Line 44 Constant Superimposed Back-Pressure (See Definition).Line 45 Variable Superimposed Back-Pressure (See Definition).Line 46 Built-up Back-Pressure (See Definition).Line 47 Total Maximum Backpressure = Superimposed plus Built-upbackpressure.Line 48 Cold Differential Test Pressure (CDTP)The cold differential set or test pressure is the actual pressure at which thevalve will open on a test stand. As PZVs are usually set and tested atambient temperature with no backpressure, the CDTP includes anynecessary correction for the actual application, based upon backpressureand / or temperature. Backpressure correction is only needed forConventional PZVs and it addresses constant backpressure only.CDTP (Conventional PZV) = (Set Pressure – Constant SuperimposedBack Pressure) * Temperature Correction Factor.CDTP (Bellows or Pilot PZV) = Set Pressure * Temperature CorrectionFactor.The Pressure adjustment for temperature is specific to the Manufacturerand PZV Model. Consult the manufacturer for discharge temperaturesabove 150°F.Line 49 Net Spring Setting (for Spring Selection)The setting that is adjusted for constant backpressure for conventionalPZVs. This is used for spring range selection.Next Planned Update: 17 July 2017 Pressure Relief Valve Conventional and Balanced TypesLine 50 Accumulation in Percent = (Relieving Pressure - MAWP) / MAWP] *100 Overpressure in PSI = Relieving Pressure – Set PressureExample:Set Pressure = 95 PSIGMAWP = 100 PSIGRelieving Pressure in Vessel = 110 PSIGAccumulation = [(110 -100) / 100] *100 = 10%Overpressure = 110 PSIG - 95 PSIG = 15 PSIGLine 51 Blowdown in Percent = (Set Pressure - P closed) / Set Pressure ) * 100Where P closed = Pressure at which the relief valve closes after openingExample:Setpressure = 100 PSIGRelief Valve Closes at 96 PSIG after opening.Blowdown = [(100 PSIG - 96 PSIG) / 100 PSIG] * 100 = 4%Blowdown should be specified as 2-4% for PZV's in ASME SECI steam service. For other valves 7-9% is generally acceptable.Line 52 Discharges To:Examples:Atmosphere, Grade, Open Funnel, Closed Sewer, Relief Header, FlareHeader, Storage Tank, Pump Suction, etc.Line 53 Maximum Allowable Bellows Back PressureTo prevent damage to, or rupture of, the bellows. This information is tobe supplied by the selected Vendor.Check that the sum of the Superimposed and Built-up Backpressure isnot greater than Line 51.Page 2 – ISS 8020-611-ENGLine 55 Instrument Tag Number - Required on every ISS individual sheet.Line 56 Calculated Maximum Tail Pipe VelocityThis is derived by dividing the Maximum Required Flowrate by thecross-sectional area of the discharge flange. (Ft/Sec) “N/A” if Line 56 isNext Planned Update: 17 July 2017 Pressure Relief Valve Conventional and Balanced Types “N/A”.Line 57 Design Limit on Tail Pipe VelocityRelief System Evaluation for stress on the discharge flare header.For Line 56 choose either Yes or N/A to indicate whether detailed flareheader sound pressure level calculations are required.Input “No” for Line 57 if any of the following items 1-3 are True.1. The PZV does not discharge to a closed system.2. The PZV is for liquid relief.3. The Screening Process indicates obvious safe sound pressure levels.Screening ProcessPerform either Test I, II or III depending on the PZV downstream pipingconfiguration.If the test result is False, then N/A may be entered into Line 57. If thetest results is True, then a Yes is entered into Line 57 to indicate thatfurther downstream piping sound pressure levels are necessary.The calculation sound pressure levels are outside of the scope of the8020-611-ENG specification sheet. The Process Engineering Divisionmay be consulted for help with the detailed sound pressure levelcalculations.Test I - PZV Downstream line size 16 in. and greater:Screening Test: The Mass Flow Rate is greater than91,000 kg/hr (200,000 lb/hr) OR the pressure ratio is greaterthan 3? (True / False)Test II - PZV Downstream line sizes 8 in. to 14 in.Screening Test: The downstream line velocity is greater than50% sonic (0.5 Mach) AND the pressure ratio is greater than 3.(True / False)Test III - PZV Downstream line size less than 8 in. AND is swaged upOR“Teed” to an 8 in. or larger line size.Screening Test: The downstream line velocity is greater than50% sonic (0.5 Mach) AND the pressure ratio is greater than 3.(True / False)Next Planned Update: 17 July 2017 Pressure Relief Valve Conventional and Balanced TypesScreening Process Definitions:Line Velocity = (Maximum PZV Discharge Flowrate)(Cross-sectional area of downstream PZV piping)Sonic Velocity = SQRT (kqRT)(See Crane - “Flow of Fluids” Chapter 1 Equation 1 - 10.)Pressure Ratio = (Built-up Pressure + Normal Flare Header Pressure + 14.7)(Normal Flare Header Pressure + 14.7)Built-up Pressure = See Definitions of TermsLine 58 Calculated Line Piping Pressure LossCalculate the Inlet Pressure drop at the maximum rated relief capacity ofthe PZV. (The stamped rated capacity of the valve).The inlet pressure losses are the accumulative pressure drops due tofriction (as a function of pipe size and length and fluid velocity),entrance and exit losses where they exist, and losses due to valves andfittings. (See Crane “Flow of Fluids” Chapter 1 for more details.)Line 59 Inlet Pressure Loss Limit (3% Set Pressure)Verify that inlet piping pressure loss does not exceed 3% of the setpressure limit (the inlet piping should be as short as possible to minimizethe pressure drop).Inlet Pressure Loss Limit = (Set Pressure * .03)An engineering analysis of the valve performance at higher inlet lossesmay permit increasing the allowable pressure loss above 3%, however,this would require a waiver.Line 63 Spring Range in PSIG (e.g., 80-150 PSIG)This is supplied by the vendor. For existing springs, the range may befound by supplying the stamped part number to Supervisor, OperationsInspection Engineering Unit, Dhahran.

The back pressure correctionfactor applies to balanced-bellows valves only. K b values can bedetermined from Figure 27 of API RP 520 Part I. (K b = 1 for backpressure less than 30% of the set pressure.)Line 86 Superheated Steam Correction Factor (K SH) - For saturated steam at any pressure, K SH = 1. For Superheated steam, K SH values can bedetermined from Table 10 of API RP 520 Part I.Line 87 Napier Correction Factor (K N) = 1 where P1 < 1515 PSIA.K N = (0.1906P1– 1000) / (0.2292P1– 1061), where P1 > 1515 PSIAand < 3215 PSIA.Line 88 Back Pressure Correction Factor (K W) - This is for balanced-bellows valves in liquid service with back pressure. For atmospheric backpressure, K W = 1. Conventional valves require no special correction.K W values can be determined from Figure 31 of API RP 520 Part I.

The permissible accumulation for various conditions is specified in the ASMECodes.Commentary Note:Accumulation is the same as overpressure when the PZV is set at the MaximumAllowable Working Pressure of the vessel.Back Pressure: the pressure on the discharge side of a relief valve. Different types of back pressures are:a) Superimposed Back Pressure: the pressure on the discharge side of a reliefvalve, against which the valve must begin to open. It may be constant or variable.b) Built-up Back Pressure: the pressure on the discharge side of a relief valvedeveloped as a result of flow due to the valve in question relieving into thedischarge header system. Where multiple valves relieve under a singlecontingency, the back pressure increase in the discharge system as a result of allinvolved valves relieving, determines the built up back pressure.Built-up Back Pressure is calculated by adding all of the discharge header pressuredrops. The pressure losses are the accumulative pressure drops due to friction (asa function of pipe size and length and fluid velocity), entrance and exit losseswhere they exist, and losses due to valves and fittings. (See Crane “TechnicalPaper No. 410” Chapter 1 for more details.)Built-up back pressure may be taken as zero for PZV's that discharge toatmosphere through a full size elbow and short discharge pipe leg.Balanced Safety Relief Valve: a pressure relief valve which incorporates means ofminimizing the effect of back pressure on the operational characteristics (openingpressure, closing pressure, and relieving capacity).Blowdown: the difference between the set pressure and the resetting pressure of arelief valve, expressed as a percentage of the set pressure or in kPa (psig).“Cold” Differential Test Pressure: the pressure in kPa (psig) at which a relief valve is adjusted to open on the test stand. This pressure includes the correction for maximumsuperimposed back pressure (for conventional non-bellows valve only) and/ortemperature service conditions.Conventional Safety Relief Valve: a pressure relief valve which has its spring housing vented to the discharge side of the valve. The operational characteristics (openingpressure, closing pressure, and relieving capacity) are directly affected by changes ofthe back pressure on the valves.Next Planned Update: 17 July 2017 Pressure Relief Valve Conventional and Balanced Types Design Pressure: the pressure, exclusive of any static heads, used to determine theminimum permissible thickness or physical characteristics of the different parts of thevessel.Disc: the pressure containing movable element of a pressure relief valve which effects closure.Lift: the amount the disc rises above the seat in pressure relief valves.Maximum Allowable Working Pressure (MAWP): the maximum pressure in kPa(psig) permissible at the top of a completed vessel in its operating position for adesignated temperature. It is the highest pressure at which a relief valve may be set tobegin to open.Nozzle: a pressure containing element which constitutes the inlet flow passage andincludes the fixed portion of the seat closure.Operating Pressure: the pressure at the top of a pressure vessel at which the vesselsnormally operates.Overpressure: the pressure increase over the set pressure of the primary relief valve.It is the same as accumulation when the relief valve is set at the maximum allowableworking pressure of the vessel.Rated Capacity: the percentage of measured flow at an authorized percentoverpressure permitted by the applicable code. Rated capacity is generally expressed in pounds per hour (lbs/hr) for vapors; standard cubic feet per minute (SCFM) for gases;and in gallons per minute (GPM) for liquids.Relief Valve: an automatic pressure-relieving device actuated by the static pressureupstream of the valve, and which opens in proportion to the increase in pressure above set pressure. It is used primarily for liquid service.Commentary Note:For the sake of simplicity all pressure relief devices (valves) referred to in this procedureare called “PZV”.Relieving Pressure: the pressure in the protected vessel with the relieving devices full open. It is the set pressure plus the actual overpressure. Relief valves shall be sized to prevent the relieving pressure from exceeding the Maximum Allowable WorkingPressure plus the allowable accumulation.Safety Relief Valve: an automatic pressure-relieving device suitable for use as either a safety or relief valve. It is used in gas or vapor service or for liquid.。

Inhazardous locations equipment grounding conductors run in conduit or cable tray shall beinsulated or enclosed within the jacket of a multi-conductor cable.Exceptions:Conduit or cable armor may be used in accordance with the NEC for groundingelectronic instrumentation operating at 24 V DC nominal or below.Cable armor, if properly sized and terminated with cable terminators that areapproved for grounding purposes may be used for equipment grounding inaccordance with the NEC (cable armor must be a type that is specifically permittedby the NEC for such use) provided the cable runs in one continuous length (nosplices or intervening junction boxes are permitted) from the substation orequipment controller to the equipment being grounded and the cable is not in directcontact with the soil for any portion of the run. Repairs to existing cable meetingthe requirements are permitted provided armor of the two sections is properlybonded.Commentary Note 9.1:In accordance with the NEC an equipment grounding conductor is not requiredbetween the neutral point of a transformer and a service disconnecting means.The grounded circuit conductor (neutral) required by the NEC is sufficient. SeeNEC Article 250-142.9.1.1 Aluminum cable trays containing only circuits operated at, or below, 50 V to groundmay be used as equipment grounding conductors provided that NEC requirementsfor such use are met. On other aluminum cable trays, a common equipmentgrounding conductor external to the cables in the tray may be used under thefollowing conditions:∙This common conductor shall be sized in accordance with NEC Table 250-122for the largest power conductor in the tray, with a minimum size of 25 mm² (#4AWG).∙Connections shall be made between this common grounding conductor andother grounding conductors for intersecting or branch trays, and to extend theequipment grounding conductor beyond the tray.∙This common conductor (or the largest individual grounding conductor, if morethan one are installed) shall be bonded to each section of the cable tray systemwith a connector approved for a copper to aluminum connection.9.1.2 A cable concentric neutral, if properly sized and not used as a current carryinggrounded circuit conductor (3 phase 3 wire system; no neutral loads are served), maybe used as the equipment grounding conductor.Next Planned Update: 1 October, 2008 Grounding Commentary Note:The cable must meet the requirements of 15-SAMSS-502 that requires anoverall jacket to protect the concentric neutral.9.1.3 Electrical submersible pump motors in oil and water well service do not require adedicated equipment grounding conductor, provided the motor controller has groundfault detection. The well head must be bonded by an approved means to the groundbus at the motor controller or supply transformer.9.1.4 Armored submarine cables do not require equipment grounding conductors.9.2 Shields and armor of power cable shall be grounded at both ends. Continuity at splices shallbe maintained by bonding across the splice.Commentary 9.2:Installation of voltage limiters may be necessary if cable shields and armor are notgrounded at both ends.9.3 Metallic conduit shall be grounded at both end points by bonding to a grounding conductor, agrounded metal enclosure, or to a grounded metal cable tray. This may be accomplished:∙with approved grounding clamps and conductors connected externally to the conduit or∙by bonding to a grounded enclosure using integral threaded bushings or using a conduit hub (15-287-xxx or equal) which is approved for grounding purposes or∙bonding to a grounding conductor using an approved grounding bushing (15-287-409 or similar). Grounding with locknuts is not acceptable. or∙where non-PVC coated rigid conduit is used to protect cable entering or exiting a grounded metal cable tray, by bonding with a conduit clamp to the cable tray. Agrounding bushing must be used with PVC coated conduit.Exceptions 9.3:Where EMT is permitted it may be grounded and bonded using any meansaccepted by the NEC.Isolated sections of rigid metal conduit that are buried at all points at least 0.5meters below grade are not required to be grounded. (e.g., Conduit sleeves forroad crossings.)Conduit sleeves used to enclose power cables transitioning from above grade tobelow grade are required to be grounded only at the above grade end.9.4 Metallic cable trays shall be bonded at both end points and a minimum of every25 m to the local ground grid or ground electrode or to structural steel which is bonded to thelocal ground grid or ground electrode.9.5 Ground busses in switchgear, switchboards, and motor control centers shall have two。

This procedure also assigns responsibilities for those associated with these documents.Documents2 ApplicableThe requirements contained in the following documents apply to the extent specified in this procedure.¾Saudi Aramco Engineering ProceduresProposalSAEP-14 ProjectSAEP-103Metric Units of Weights and MeasuresSAEP-133Instructions for the Development of "RegulatedVendors List" Engineering StandardsEstablishing and Maintaining SAEP-301 InstructionsforMandatory Saudi Aramco EngineeringRequirementsforObtaining a Waiver of aSAEP-302 InstructionsMandatory Saudi Aramco EngineeringRequirement¾Saudi Aramco Engineering StandardSAES-A-112Meteorological and Seismic Design Criteria ¾Saudi Aramco Standard DrawingAE-036411Drawing and Equipment Index Key3 Instructions3.1 Definition and ApplicationSAESs are standards, approved by Saudi Aramco Management, that establishminimum mandatory requirements for the selection, design, construction,maintenance, and repair of equipment and facilities. The requirements in thesestandards apply Company-wide. All capital, non-capital and expense projectsunder the control of Engineering and Project Management shall use SAESs ineffect on the Project Proposal approval date. See SAEP-14. MaintenanceNext Planned Update: 15 October 2013 Preparation of Saudi Aramco Engineering Standards projects and all other work performed without Project Proposals shall useSAESs in effect when the work is authorized.Standards are generally not applied retroactively to the maintenance and repairof existing facilities. However, new or revised standards which impact existingfacilities regarding safety, environmental protection, health, or security shall bereviewed by operating organizations with Industrial Security, Loss Prevention,Consulting Services, Process & Control Systems Department, and others, todetermine applicability and extent of implementation. For on-going or activeprojects, operating organizations shall include Project Management in theirreview to evaluate cost and schedule impact. Review decisions shall bedocumented for appropriate levels of Management.The development and maintenance of “Regulated Vendors List” EngineeringStandards are governed by SAEP-133.3.2 FormatBase the structure of all SAES documents on one of two styles: Exception orNarrative.3.2.1 Exception-style SAESs define requirements as additions, modificationsor deletions to the requirements in an industry standard, using theindustry standard's chapter/sections/paragraph numbering system. Usethis style when an industry standard already defines the majority ofSaudi Aramco's requirements. This is the preferred style because itreduces the number of requirements that must be generated andmaintained. It also offers the benefit of alerting users to the Company'sspecial requirements. See Attachment I for details of this style. Avoidrepeating unchanged parts of the industry standard in the SAESs.3.2.2 Narrative-style SAESs are used when the Standards CommitteeChairman determines that an appropriate industry standard does notexist. He may supplement the content of one, or more, industrystandards, but the requirements are not written as exceptions. Tailor thedocument structure of this style to meet the specific needs of the subject.See Attachment II for additional details associated with this style.3.3 Contents3.3.1 Write using simple, easy-to-understand language. Active sentences arepreferred. They are usually shorter and more explicit than passivesentences. Use the verb “shall” to indicate mandatory requirements.Next Planned Update: 15 October 2013 Preparation of Saudi Aramco Engineering Standards Establish the wording of the title as carefully as possible. It shallindicate, concisely and without ambiguity, the subject matter of thestandard in such a way as to distinguish it from that of others, withoutgoing into unnecessary detail. Any necessary additional particulars shallbe given in the scope.Every standard shall begin with a scope section. Here, define withoutambiguity, the subject of the standard and the aspect(s) it covers. Thescope shall not contain requirements.To assist Users of SAESs, locate requirements in SAESs that are mostclosely aligned with their discipline, as defined by Standard DrawingAE-036411.Include in SAESs, all requirements needed by engineers, maintenanceorganizations, inspectors, contractors, vendors (for SAESs written forattachment to procurement documents), and any others involved with theselection, design, construction, maintenance, or repair of Companyequipment and facilities.To avoid the occurrence of duplicate or conflicting requirements, do notextract and repeat requirements from Saudi Aramco Materials SystemSpecification (SAMSSs), or other SAESs. Instead, if a requirement isneeded in both a SAES and a SAMSS, locate the requirement in theSAMSS and make reference to it in the SAES. Include all mandatoryparagraphs shown in Attachment I.Make reference to the content and details of Standard Drawings, to theextent they apply. To assist equipment or material specifiers in correctlyusing SAMSSs, include information needed to make decisions to fill-outequipment data sheets.Include definitions of technical terms used in the SAES. Do not includenontechnical provisions already covered in Saudi Aramco's standardterms and conditions for contracting and purchasing, such as risk of loss,liability for failure or damages, warranties, rights to inspect, and othersuch legal matters. Check with the Law or Purchasing Departments if indoubt.Pay attention to the way requirements are stated. Be aware that whendesign or construction alternatives (material selection, etc.) are allowedin a SAES, the decision-making criteria and thought process for a Lump-Sum-Turnkey contractor (“minimize first costs”) may be completelydifferent from and contrary to those for a Saudi Aramco engineer(“minimize total life-cycle costs”). Where there is a need to review orNext Planned Update: 15 October 2013 Preparation of Saudi Aramco Engineering Standards approve certain technical items covered by the SAES (alternate designs,repairs, welder qualifications, test procedures, etc.) by someone in SaudiAramco at Manager level, or below, indicate this responsibility bydesignating a specific position (Standard Committee Chairman, UnitSupervisor, Division Coordinator, etc.). Do not use general titles such as“the Saudi Aramco Engineer” unless this term is clearly defined withinthe body of the document. See Attachment I for an example.To avoid any misunderstanding about the use of SAESs, specificauthorization must be included within the body of the document to allowit to be referenced in and made a part of purchase orders. Without thisauthorization, it may not be included in purchase orders. SeeAttachment I for an example.3.3.2 Give preference to referencing SAESs to the “latest edition” of anindustry standard. However, the Standards Committee Chairman maydecide that reference to a specific edition of the industry standard, willbest satisfy the needs of the Company.3.3.3 Use the International System (SI) of Units in SAESs, following theinstructions of SAEP-103, Metric Units of Weights and Measures.3.3.4 Where additional information or explanation is needed to clarify theintent of a requirement or where there is a reasonable chance ofmisinterpreting or misapplying the requirement, include a commentarynote. Make the note brief, limiting it to only the essential items. Todistinguish it from the SAES requirements, label the note“COMMENTARY” and use italics. See Attachment I for an example.3.4 DeviationsDeviations proposed by any organization that result in facilities meeting lessthan the minimum requirements require waiver approval in accordance withSAEP-302 before proceeding with design or construction. For deviationsidentified after the start of design or construction, the waiver approval isrequired prior to design or construction completion.3.5 ApprovalUse the approval process outlined in SAEP-301 “Instructions for Establishingand Maintaining Mandatory Saudi Aramco Engineering Requirements” todevelop new SAESs and revise existing SAESs. To keep SAESs current andup-to-date, conduct a major review and revision of every SAES at least everyfive (5) years, or other appropriate interval established for the document.Next Planned Update: 15 October 2013 Preparation of Saudi Aramco Engineering Standards3.6 Cancellation of SAESCancel existing SAESs by obtaining the signature of the Approval Authority.4 Responsibilities4.1 Standards Committee Chairman (SCC)The SCC is responsible for doing the following:- Determining the need for SAESs, and if required, developing them, making decisions about their style and contents.- Verifying the cost-effectiveness and technical adequacy of the minimum technical requirements contained in the SAESs.- Conducting a major review of every SAES at least once every five years.- Forwarding draft documents to the Standards Coordinator to either route for BOE review or for the completion of approval, publication, and distributionprocesses per SAEP-301 paragraph 4.7(g).- Coordinating the SAESs requirements with the RSA Representative.4.2 Standards Coordinator (SC)Ensure that the information of all approved SAESs is disseminated perSAEP-301 paragraph 4.7(g).SummaryRevision15 October 2008 Revised the "Next Planned Update".

浅谈沙特阿美非常规钻机的设备验收

浅谈沙特阿美非常规钻机的设备验收

浅谈沙特阿美非常规钻机的设备验收摘要沙特阿美石油公司以其严格的安全标准闻名于世。

沙特阿美石油公司非常规钻井部起源于探井钻井部,是对安全要求最为苛刻的部门。

本文将以SPXXX队新钻机验收检查为例,浅谈沙特阿美非常规钻机的设备验收。

关键词:安全;标准;非常规;验收沙特阿美石油公司新钻机验收生产(设备)部分以及安全部分以检查单的形式进行。

在检查过程中,除执行沙特阿美石油公司的通用标准之外,非常规钻井部的验收将更加苛刻,其对于相关标准的解读和执行也更加严格和深入。

本文将主要就新钻机验收检查中钻井队因为前期设备建造过程中疏忽而造成的问题进行总结,以期在今后的新钻机建造验收过程中能够节约人力物力,尽早通过验收。

新钻机验收安全部分主要由沙特阿美石油公司DOE&CD(钻修井作业合规部)派往现场的安全官完成。

该部分检查的主要依据来自于沙特阿美石油公司钻修井部的HSERM(健康、安全、环境要求手册)和SWIM(安全作业指导手册)。

因此,为顺利通过新钻机开钻验收,熟读这两本手册非常有必要,当安全官提出不合理的要求时,可以依据这两本手册的内容对其不合理要求进行反驳。

下文将对新钻机验收安全按照类别分别进行说明。

1 设备合格证及相关文档资料设备合格证,即COC(certificate of compliance),符合性证明,是对符合标准要求的产品颁发的证书,可以简单理解成设备合格证。

设备合格证标明设备的序列号、制造日期等关键内容,是验证设备可追溯性的重要证据。

无论是在非常规钻井部的开钻验收检查还是在开钻以后的设备三类、四类检测中,设备合格证都是必须提供的证书。

设备合格证不仅仅需要收集各种主体设备如井架、底座、钻机、泥浆泵、天车、游车、顶驱等的合格证,还需要收集如泄压阀(PRV)、气罐、天车游车滑轮、起升滑轮等的合格证及相关支撑文档。

尤其是泄压阀,遍布设备的各个角落,如泥浆泵、灌注泵、气瓶、空气压缩机、各个液压站等处。

They shall have proper training and skills toconduct the job.4 Pre-Assembly Inspection4.1 The gasket shall be verified for correct type, rating, dimension and compatibilitywith the flange facing. Also, it shall be free from any damage particularly in theseating element. Ensure that spiral wound gaskets are stored flat especially forlarge sizes, 24 inches and larger.4.2 Bolts, nuts and washers shall be visually checked for proper size, grade,dimension and for any physical damage to shanks or threads which would affectthe bolt assembly or performance. Also, check the suitability of the stud boltsand nuts material for the service temperature and the compatibility with theflange material.4.3 The flange facing, particularly the seating area, shall be visually examined forcleanliness and ensure that no damage, such as scratches exist.For ring joint type flanges, the ring and the ring groove shall be free of damageand dirt.4.4 Proper lubricant for bolts and nuts shall be used. Lubricant for bolts and nuts shallbe Jet-Lube SS-30 or other acceptable lubricants listed in Table-SAEP-351-01.4.5 Tightening tools shall be checked for adequacy, performance and calibration, ifrequired.4.6 Lubricant shall not be used in the gasket and the gasket seating area.4.7 Flange shielding shall be installed/reinstalled when required.Next Planned Update: 12 May 2017 Bolted Flange Joints Assembly Commentary Note:Flange shielding is normally used for personnel protection against possible liquidsplash or high temperature during operation.5 Torquing5.1 Torque values vary according to flange rating, bolt size, type of gasket, andfriction factor of the thread lubricant.5.2 The torque values are specified in Table-SAEP-351-02 and Table-SAEP-351-03.5.3 Table-SAEP-351-02 applies to all gaskets listed in SAES-L-109, except forinsulating gaskets.5.4 Table-SAEP-351-03 applies to isolating gaskets (e.g., PIKOTEK), based on afriction factor of 0.16.6 Torquing Tools6.1 There are various types of tools available to achieve the proper torque value.Selection of the proper tool depends on the stud bolt size, physical location ofthe flanged joint, and criticality of the flange. Identifying the proper tools shallbe resolved between Contractor, SAPMT, Proponent and Inspection prior tocommencing the erection of the piping.6.2 The manufacturer's instructions shall be followed for the operation, limitationand maintenance of all torque wrenches used to perform flange bolts tightening.6.3 Torque wrench calibration shall be performed in accordance with manufacturer'srecommendations.7 Stud Bolt Tightening ProcedureStep 1 Align flanges and gasket. Forced tightening is not allowed to overcome non acceptable alignment tolerances. Clamp securely in place.Step 2 Apply lubricants to stud threads over length and nut engagement and to face of nut which contacts flange. Ensure that the nuts run freely down the thread ofthe studs.Step 3 Install all studs and nuts hand tight, ensure that studs pass freely through the flange holes. Position the nut on one end of the stud such that only the crownof the stud projects beyond the face of the nut. The excess stud length shouldproject beyond the nut on the other side.Next Planned Update: 12 May 2017 Bolted Flange Joints Assembly Commentary Note:By doing this, the nut that is installed nearly flush with the end of the stud canbe easily removed since the threads are not coated, and normally have notbeen subjected to corrosion. The side of the stud with the flush nut should bechosen by taking into consideration factors such as whether one side has betteraccess for maintenance personnel and/or tightening tools, e.g., torque wrenchor impact wrench, etc.Step 4 Number each stud according to its position in the flange as shown on Figure 1: Stud Bolt Tightening Sequence.Step 5 For insulting gaskets like PIKOTEK, enough gap (½" of gap is recommended) should be available between flange faces to avoid any damage to seals duringinserting the gaskets, if due to any reasons, seals are damaged, change the sealbefore installing PIKOTEK.Step 6 Matting flange faces and the gaskets should be dry and free from grease, oil or water.Step 7 Tighten studs per the Stud Bolt Tightening Sequence, for 4 to 32 bolts use Figure SAEP-351-01 and for 36 to 68 bolts see Figure SAEP-351-02 for boltsnumbering and then follow the tightening sequence of Table SAEP-351-04.An appropriate tool should be used such as an air impact wrench or equivalent.Step 8 For joints containing RTJ or Spiral Wound Gaskets, repeat step 7.Step 9 Tighten the stud bolts in stages to obtain the final required torque from the appropriate torque Table-SAEP-351-02. The first stage should not be morethan 30% of the final torque. The final torque shall be within ±5% of therequired torque value.Apply the torque evenly to each stud following the stud bolt tighteningsequence. The final torque must be within ±5% of the required values perSection 7 above.8 Stud Bolt Additional Tightening Procedure where Leaks Occur DuringPressure TestingStep 1 Depressurize the piping system and re-torque stud bolts to maximum torque value shown on Table-SAEP-351.Step 2 If leak does not stop after re-torquing has been performed, disassemble the flange joint and inspect as follows:a. Inspect stud bolts and nuts for defects or damage to threads or impropercleaning of threads.Next Planned Update: 12 May 2017 Bolted Flange Joints Assemblyb. Inspect flange faces for damage, misalignment.c. Inspect gasket for damage or defects.Step 3 After all defective and damaged items have been repaired or replaced,reassemble the flange joint using a new gasket and tighten the bolts using themaximum torque values.Table-SAEP-351-01 – Friction Factors for Different LubricantsNext Planned Update: 12 May 2017 Bolted Flange Joints Assembly Table-SAEP-351-02 – Torque Values for Low-Alloy Steel BoltingNotes:1) Torque values are based on 50,000 psi prestress on stud bolts and Friction Factorof 0.16 for noncoated surfaces and 0.12 for new coated surfaces. A combination ofvarious elements such as the conditions of the threads, the condition of the flange tothe nut bearing surface and the type of lubricant used, makes up the friction factorwhich can vary from .04 to .20 or as much as 500%.2) Torque values for stainless steel or other alloy stud bolts can be obtained bymultiplying the ratio of the specified minimum yield strength (SMYS) of stainless steelstud bolts to A193 B7 stud bolts, to the torque values in the Table-SAEP-351-02.The SMYS values for all bolting materials are listed in ASME B31.3 code(Note:SMYS depends on grade, class and size).Next Planned Update: 12 May 2017 Bolted Flange Joints Assembly Table-SAEP-351-03 – Torque Values for Isolating Gaskets (PIKOTEK)on ASME B16.5 and ASME B16.47 Series A & B,Class 150 Through Class 2500 FlangesNote: Torque values based on 30,000 psi tension load and 0.16 Friction Factor fromAPI BULL 5A2 thread compound. See Table-SAEP-351-02 Note (1) for other factors.Commentary Notes:a) For ASME Class 900 through Class 2500, API-6B and API-6BX Class 2000 through Class 15000,and RTJ Flanges, the maximum compressive stresses induced during installation should not exceed25,000 psi. Design to 12,500 psi when possible.b) Calculations for compressive stresses applied during torque-up procedures must account for ringjoint grooves, gasket seal grooves, raised face diameters, and gasket inside diameter.(See PIKOTEK Gasket User's manual).c) Bolt tensioning equipment such as HYDRATIGHT may be used for class 900 and above resulting ina minimum residual bolt stress of 30000 psi and a maximum of 50,000 psi. Refer to PIKOTEKGasket User's manual for specific bolting instructions.Next Planned Update: 12 May 2017 Bolted Flange Joints Assembly Figure SAEP-351-01 – Stud Bolt Tightening Sequence (4 to 32 Bolts)Next Planned Update: 12 May 2017 Bolted Flange Joints Assembly Figure SAEP-351-02 – Stud Bolt Numbering (36 to 68 Bolts)Document Responsibility: Piping Standards Committee SAEP-351 Issue Date: 12 May 2012Next Planned Update: 12 May 2017 Bolted Flange Joints Assembly Table-SAEP-351-04 – Cross-Pattern Tightening Sequence(36 to 68 Bolts) per (ASME PCC-1)Revision Summary12 May 2012 Revised the "Next Planned Update".
