EO and EO-2 Metric Bite Type FittingsThe Fitting AuthorityInsert for Metal TubeEO Progressive Ring Fittings —IntroductionThe flareless bite type fitting was pioneered by Ermeto in Germany in the early 1930's. When Parker Hannifin acquired Ermeto, it introduced the EO fittings to the US. Today, the EO fittings are the most widely used bite type fittings in the world.The EO progressive ring fitting is a flareless metric fitting (for metric tube)that consists of a body, a progressive ring (ferrule)and a nut. On assembly, two cutting edges of the progressive ring “bite ” into the outer surface of the tube ensuring the necessary holding power and seal for high operating pres-sures.*The selection of LL, L or S design should be made by the user on the basis of intended system pressure. The pertinent maximum recommended working pressures are shown throughout this catalog in individual data charts of the various fitting configurations.demanding service conditions that exist in industry today. The original progressive ring, known as DPR, is now being replaced with the new generation, called PSR. PSR is stronger and features a “positive stop ” to eliminate over-tightening.The EO Nut. EO fitting nuts are either cold formed, hot formed or machined from cold drawn material. The cold forming and cold drawing operations provide a more tightly packed grain structure, thus improving the material's strength. In addition,cold forming significantly improves the fatigue properties or endurance limits of the nuts.Standard Material SpecificationsSteel fittings:EO tube fittings –Materials according to DIN 3859-1Stainless steel fittings:EO tube fittings –X6CrNIMoTi 17122 in accordance withDIN 17440 / EN 10088, material no.1.4571.Brass fittings:EO tube fittings –CUZN35Ni2 in accordance with DIN17660, material no. 2.0540.Elastomer seals:NBR (BUNA-N), FPM (Fluorocarbon)Surface Finish - Steel fittings:Standard LL SeriesBody, Nuts, and Rings– Zinc yellow chromateL+S Series Body and Nuts – Zinc yellow chromateProgressive Rings (DPR)– Zinc olive chromate Progressive Rings (PSR)– Zinc clear chromateShort codes for surface protection procedure in accordance with DIN 267 part 9 or DIN 50942.How EO Fittings Work: Function of Progressive Ring FittingsThe EO progressive ring fitting produces a low to high pressure,leak free connection of tubes and components in fluid systems.The basic function of the EO progressive ring is the controlled progressive bite of the ring into the tube due to a unique internal geometry.The front cutting edge has already started cutting into the tube before the second cutting edge starts. As soon as both cutting edges have cut the tube to the designed depth further advance is limited by the stop edge.Owing to the design of both cutting edges and stop edge all forces arising are equally distributed. This distribution along with the specially designed interior collar of the ring guarantees increased safety, particularly with regard to vibration and flex-ure stresses. The design and function of the progressive cutting ring ensure that service vibration loading is not present in the areas of the tubing where the bite is made.Fig. H1 — EO fitting components: Body, progressive ring and nutThe fittings and components listed in this catalog are intended solely for the assembly of connections for fluid applications.Three series of EO tube fittings (LL, L and S) and accessories are manufactured in accordance with DIN 2353 (summary) on the basis of decades of experience.*To ensure functional safety of EO tube fittings, only EO parts should be used in their assembly. Routing of tubes should be carried out in accordance with Parker/EO recommended prac-tices. Assembly instructions are available.Design and ConstructionThe three components of EO fittings are designed and manu-factured to produce a strong, reliable, leak-free joint upon proper assembly.The EO Body. EO fitting bodies are available in over thirty configurations. The shaped products (i.e., elbows, tees, crosses)are hot forged, then machined to the stringent EO fitting speci-fications. The forging process used by Parker further improves the strength and metallurgical properties of the fitting material.Straight products are made from cold drawn bar stock. The cold drawing operation ensures consistently tight dimensional toler-ances, as well as significantly improved strength.The EO Progressive Ring (Cutting Ring). EO progressive rings are precision machined with all dimensions and surfaces,particularly the critical bite edges, monitored on an ongoing basis. The rings are then heat treated in a manner that provides the hardness, strength, and toughness necessary to satisfy theSecond bite edgeFront bite edgeFig. F2 — How EO fittings workFitting Instructions:The life of a rotary fitting depends considerably in a stress-free line connection. Therefore, the direct connection with tube is to be avoided. For connection to hoses, the use of swivel nut fittings is recommended with short, straight lines (approx. length 5x hose O.D.). Thus, shocks and vibrations can be absorbed.Non-Return ValvesCharacteristics: Sealing is achieved by using a 90° cone with a packing washer of synthetic material. Valve has a lift stop which provides safe free outlet, shock-absorbing, muffled open-ing and no reduction of cross section. Maximum flow velocity not more than 8 m/sec (for higher flow velocities special tests are required).Opening Pressure: Approximately 1 bar (on request also 0.5-2 and 3 bar are available. Please specify on order). Tolerance of opening pressure is ±20%.Tube RecommendationsFor steel fittings:Seamless cold drawn steel tubes made from material St. 35.4 or from conditioned base material St. 37.4 in accordance with DIN 1630, state of delivery NBK (normal annealed) with tube outer and inner diameter tolerances in accordance with DIN 2391/ISO 3304. Max. hardness: HRB 75.For stainless steel fittings:Material no. 1.4571 and 1.4541Seamless drawn tubes made from austenitic, stainless steel materials no. 1.4571 and 1.4541, in accordance with DIN/EN/ ISO 1127. Max. hardness: HRB 90.These tubes are particularly recommended for tube fittings, since the tube outer diameter and wall thickness, tolerances correspond to those of steel tubes in accordance with DIN 2391/ISO 3304.For brass fittings:Seamless drawn copper tube made from material with short code SF-Cu F37 in accordance with DIN 1786.Tube wall thicknesses:In order to determine the necesary tube wall thicknesses for applications, refer to the calculated pressures provided in the tables for EO metric tubing. The calculated pressures DIN 2413-I are for static and DIN 2413-III for dynamic loads.The maximum wall thickness is based on the pressure holding capacity of the fitting. In some cases, the wall thickness of the tube might be too thin for reliable service and an insert must be used to prevent excessive tube collapse. See assembly sec-tion for recommended tube wall thicknesses.Plastic tube:EO fittings are suitable for use with various types of plastic tubes such as nylon, polyethylene, etc. When used with plastic tube, an insert (see page F14) must be used to prevent tube pull out due to tensile loading.Features, Advantages & Benefits•Visible Bite — The critical front bite of the progressive ring is clearly visible to tube fitters & inspectors. The presence of the recommended bite virtually eliminates any risk of catastrophic blow-off. This is a very important safety fea-ture.•Sealing Capability — EO fittings have demonstrated a remarkable ability to remain leak free under various ser-vice conditions ranging from sealing high vacuum and small molecules gases to high pressure hydraulic fluids.•Distributed Stresses — Stresses due to service flexural loading are distributed at several points in the joint, thus stress concentration in the bite is minimized.•Vibration Control — The rear bevel of the ferrule firmly grips tubing, thus dampening the effects of system vibra-tion in the joint.•Progressive Ring Design — The progressive ring design provides a second bite for improved reliability and higher working pressure capability. This design also decreases the risk of improper assembly because of the sharp, high torque rise which occurs when the fitting is properly tight-ened.•Envelope Size — EO fittings are relatively small and compact, making it a suitable selection for plumbing in limited or tight space.•Temperature Rating — EO fittings are suitable for sub-zero through elevated temperature applications. Service temperature rating is limited by the material chosen.•Compatibility — Since EO fittings can be manufactured from a wide range of metals, its compatibility factor with various fluids and atmospheric conditions is virtually limit-less. One simply has to select and specify EO fittings from an acceptable material that best satisfies the service conditions.•Tube Wall — EO fittings are suitable for use with light wall, medium wall, heavy wall, and extra heavy wall tubing.(Light wall tube may require support sleeve (VH), as shown in Assembly/Installation Section.)•Re-Usability / Remakeability — Joints can be disas-sembled and reassembled many times to facilitate system maintenance. This reduces the labor and material costs that would otherwise result from tube and fittings replace-ment.•Assembly — No expensive, complicated tooling is neces-sary to assemble EO fittings. Assembly is simple when the procedures described in the Assembly / Installation sec-tion are followed (see pages T24 - T27).•Materials — EO fittings can be manufactured from almost any metallic material. The more popular materials cur-rently used for EO fittings are: stainless steel, carbon steel, and brass. On request, the Tube Fitting Division will ma-chine EO fittings from other appropriate material specified by users.•Manufacture — EO fittings are manufactured under tight quality control which ensures that the product routinely satisfies or surpasses the requirements of the pertinent industrial standards.•World Wide Popularity — The bite type fitting design has worldwide acceptance and is especially popular in Europe.•Finish — Steel EO fittings have a zinc gold chromatefinish. This finish provides good corrosion protection.•Silver Plated Nuts — Stainless steel tube nuts are pre-lubricated with silver plated threads (size 15L-42L, 12S-38S). Thread galling is eliminated and assembly torque isreduced as much as 40 percent. This increases the speedand efficiency for stainless steel fitting assembly.•Availability — EO fittings are available as standard in overthirty different configurations, and as many as twenty-seven different size combinations in some configurations.•Configurations — Popular configurations for EO fittingsare shown in the Visual Index. Other configurations can bemanufactured on request.EO-2 Fitting System —IntroductionDesign and ConstructionFig. F3 — EO-2: Fitting body and functional nutThe EO-2 high pressure tube fitting generation is the most recentdevelopment of the Tube Fitting Division Europe. It was intro-duced in an effort to eliminate leakage in all fluid systems.The common feature of all EO-2 fittings is elastomeric seals onall joints. This assures leakfree operation without retightening— even under severe working conditions. Another break-through in bite-type technology is the simple assembly andcost-saving handling of the unique EO-2 Functional Nut.EO-2 is a true metric design according to 24° bite-type stan-dards such as: ISO 8434-1, DIN 2353 or DIN 3861. It covers allthree series (LL, L and S) of the broad EO tube fitting program.This resulted in a great acceptance with equipment manufac-tures that are targeting an absolute leakfree systems withoutsacrificing the convenience of using metric bite type fittings.Fig. F4 — EO-2: The metallic support of the sealing ring acts justlike an integrated preassembly tool.Elastomeric SealingThe elastomeric seal assures a hermetically sealed tube joint. Itis located in between the inner cone of the fitting body and thetube surface, thus blocking the only possible leak path. Due toits large cross-section, the seal effectively compensates for allmanufacturing tolerances on tube and fitting cone.The sealing effect is pressure supported which makes the EO-2 fitting suitable for high pressure applications. The staticcompression also eliminates air-ingress into the fluid system atunderpressure conditions.Elastomerically sealed EO-2 fittings do not require any retight-ening even in heavy-duty applications. Seal extrusion is pre-vented by proper housing without gaps or dead volume. Thesealing lip is bonded to a metallic support ring.Standard Material SpecificationsSteel fittings:EO-2 tube fittings–Materials according to DIN 3859-1Stainless steel fittings:EO-2 tube fittings–X6CrNIMoTi 17122 in accordancewith DIN 17440 / EN 10088, materialno. 1.4571.Brass fittings:EO-2 tube fittings–CUZN35Ni2 in accordance with DIN17660, material no. 2.0540.Elastomer seals:NBR (BUNA-N), FPM (Fluorocarbon)Surface Finish - Steel fittings:StandardLL Series Body, Nuts,- Zinc yellow chromateand RingsL+S Series Body and Nuts- Zinc yellow chromateRings (Progressive)- Zinc olive chromateShort codes for surface protection procedure in accordancewith DIN 267 part 9 or DIN 50942.How EO-2 Fittings WorkThe retaining ring bites into the tube in accordance to the proven bite ring principle. The elastomeric seal reduces the danger of over- or underassembly by a special EO-2 design feature: Before assembly there is a gap in between the flat surfaces of the retaining ring and the metallic support ring of the seal. As soon as the retaining ring has reached the proper incision depth, the gap closes, resulting in a sharp increase of assembly torque. This results in uniform and reliable fitting assemblies. The assembly result can easily be inspected by just checking if the gap is closed.The separation of sealing and holding functions to two separate elements finally allows a more effective solution of the over-and undertightening problems typically associated with bite type fittings.Integrated Assembly ToolThe metallic support ring of the seal is made of a specially designed material and heat-treatment to act as an assembly tool. This makes sure that the retaining ring securely cuts into the tube surface without damaging the sensitive inner cone of the fitting body.This unique feature of EO-2 fittings even allows direct assem-bly of tube without any additional pre-assembly process. An EOMAT machine (or other hydraulic tool) is strongly recom-mended to allow easy assembly of large dimension tube and drastically save total assembly time, effort and costs. The integrated assembly tool of EO-2 fittings even helps to save further costs and trouble when using an EOMAT-type preset-ting machine: As the presetting cone is only in contact with the elastomeric sealing lip, it cannot be worn out or damaged even after thousands of assemblies. This not only saves replace-ment costs but also avoids leakage problems caused by worn presetting tools.The Functional Nut Individual components such as seal or retaining ring cannot be forgotten, confused or assembled in the wrong orientation. Time and cost are saved by eliminating searching and arrang-ing the components to make up individual joints.Functional Nuts are completely interchangeable with the full range of EO tube fitting ends.After assembly and disassembly, the sealing ring can be replaced individually without cutting off the tube end. Tube RecommendationsFor steel fittings:Seamless cold drawn steel tubes made from material St. 35.4 or from conditioned base material St. 37.4 in accordance with DIN 1630, state of delivery NBK (normal annealed) with tube outer and inner diameter tolerances in accordance with DIN 2391/ISO 3304. Max. hardness: HRB 75.For stainless steel fittings:Material no. 1.4571 and 1.4541Seamless drawn tubes made from austenitic, stainless steel materials no. 1.4571 and 1.4541, in accordance with DIN/EN/ ISO 1127. Max. hardness: HRB 90.These tubes are particularly recommended for tube fittings, since the tube outer diameter and wall thickness, tolerances correspond to those of steel tubes in accordance with DIN 2391/ISO 3304.Tube wall thicknesses:In order to determine the necesary tube wall thicknesses for applications, refer to the calculated pressures provided in the tables for EO metric tubing. The calculated pressures DIN 2413-I are for static and DIN 2413-III for dynamic loads.The maximum wall thickness is based on the pressure holding capacity of the fitting. In some cases, the wall thickness of the tube might be too thin for reliable service and an insert must be used to prevent excessive tube collapse. See assembly sec-tion for recommended tube wall thicknesses.Plastic tube:EO-2 fittings are suitable for use with various types of plastic tubes such as nylon, polyethylene, etc. When used with plastic tube, an insert (see page F14) must be used to prevent tube pull out due to tensile loading.Fig. F5 — The unique Functional Nut allows easy handling and quick assembly.The unique Functional Nut simplifies handling of fitting compo-nents and helps to minimize storage and procurement costs. The sealing and retaining rings are combined as a pair and are inserted into the internal thread of the nut in such a manner that they cannot fall out, so that these three parts form one func-tional element.Features, Advantages and Benefits of the EO-2 Fitting SystemIn addition to the general advantages of the EO tube fitting system, the unique EO-2 fitting features offer even more spe-cific benefits:•Sealing Capability — An elastomeric seal forms the primary sealing element, thus assuring leak-free sealing.Even low-viscosity media such as water or gas are her-metically sealed. Hydraulic systems, therefore, do not “sweat” at fittings.•High Pressure Resistance — EO-2 fittings are rated up to Pmax 900 bar. Sealing lip and seal arrangements have both been designed so that the sealing effect is supported by system pressure. The interaction of the retaining ring and the integrated preassembly tool results in uniform and reliable fitting assembly.•Durability — The elastomeric seal does not require any retightening even after years of operation under severe working conditions.•Bite Control — The ideal bite depth is controlled by the fitting design rather than by the fitters force. Closing the gap at the end of the manual assembly, the fitter gets clear signal that setting is completed and the joint is ready for inspection.•Functional Nut — Individual components such as the retaining ring or seal cannot be lost, forgotten, confused or assembled in the wrong orientation. This dramatically saves assembly cost and helps to avoid dangerous as-sembly errors.•Assembly Cost — With less than 10 seconds cycle time on the EOMAT III/A (actual presetting process: 1.4 sec-onds), the cost of presetting EO-2 is extremely low.•Integrated Preassembly Tool — Each EO-2 Functional Nut comes assembled with an integrated assembly tool that makes sure that the retaining ring securely cuts into the tube surface without damaging the sensitive inner cone of the fitting body. This greatly reduces the danger of tube blow-off, even when using stainless steel tube.•Unlimited Presetting Tool Lifetime — When EOMAT machines are used for cost-efficient presetting, the preassembly tools do not wear out as they are only in contact with the rubber seal. This avoids dangerous blow-off which can result when traditional bite-type fittings are assembled using worn presetting tools.•Make-up — From the wrench-tight position of the preset EO-2 joint, one short pull on the wrench (approx. 1/6 to 1/4 turn) gives the assembly a quick high rise to required torque. EO-2 fittings have a solid “hit-home-feel” and excellent over-torque resistance.•Visible Inspection — There is no doubt if an EO-2 Func-tional Nut has been preset correctly or not. Inspection is as simple as checking if the gap between retaining ring and sealing ring is completely closed. The tube end does not have to be disassembled out of the fitting for bite inspec-tion.•No Phantom Leaks — Lubrication is not mandatory for the assembly of steel EO-2 fittings. The machine operator will not be irritated about lubricant coming out of the fittings once the hydraulic system gets hot.•Re-Usability / Remakeability — EO-2 fittings can be disassembled and reassembled many times. There is no wear or widening of the vulnerable inner cone. Damaged seals can easily be replaced. All spare DOZ-seals are marked by size-code (e.g.: 12-L).•On-Site Maintenance — For the maintenance and re-placement of EO-2 fittings a set of wrenches is sufficient.Additional in line components, such as test points (GMA), ball valves (KH) or T-fittings can be added to an existing assembly within minutes.•Interchangeability — The EO-2 Functional Nut can be used for the whole variety of the broad range of more than50 configurations in some 25 sizes of standard EO LL, Land S-series fittings. Changeover from Progressive ring or weld nipple is easy by the simple use of EO-2 Functional Nuts.•Reliability — Millions of EO-2 fittings are working trouble-free in applications like: Mobile construction equipment, stationary machine tools, hydraulic presses, plastic injec-tion molding machines, shipbuilding, offshore exploration, submarines, railway trains and military equipment. Leak-age does not occur on EO-2 pipework.•Trouble-Free — Regular bite type fittings allow typical assembly-errors such as: confusion of bite type ring mate-rial and size. Also, the use of worn-out preassembly tool may result in fitting failure. The clever EO-2 design elimi-nates most of these mistakes without making the assem-bly process more complicated.•Popularity — EO-2 fittings are as easy to assemble as traditional bite type fittings, but they eliminate most of their typical assembly problems. EO-2 fittings are therefore appreciated by an increasing number of original equip-ment manufacturers. EO-2 also has become the fitting of choice of end-users that appreciate the leakfree perfor-mance, the easy maintenance and the global availability of the metric soft-seal bite type system.MNutDPRProgressive RingFor L and S series onlyDCutting (Locking) Ring For LL series onlyDPR:Progressive Ring D:Cutting Ring* DPR Progressive Rings in sizes 6, 8, 10 and 12mm are the same for both Series L and S.Cutting (locking) Rings, Series LL: Zinc plated and yellow chromated (A3C)ProgressiveRings, Series L and S: Zinc plated and olive chromated (A3D)PSRProgressive RingFor L and S series only* PSR Progressive Rings in sizes 6, 8, 10 and 12mm are the same for both Series L and S.PSR Progressive Rings: Zinc plated and clear chromatedAssembly /InstallationSpecsHow to OrderReferenceVITA3C VITSSA 71••••••••••••STANDARDFrom StockAssembly /InstallationSpecsHow to OrderReferenceETube InsertFor Plastic TubeVHTube InsertFor Thin Walled Metal TubeNote: E inserts are made of brass.GMBulkhead LocknoutAssembly /InstallationSpecsHow to OrderReferenceFull Dimensions Full DimensionsHow toOrderSpecsAssembly /InstallationReferenceSVBulkhead Union24° Flareless / 24° FlarelessESVWeld Bulkhead Fitting24° Flareless / 24°FlarelessFor EO-2 part number, insert “Z ” between size and pressure series.

仪表管接头
对于图示的连接头，因为左端接头为平口，安 装方式同管接头，要用卡环。右端的接头为锥口， 不用卡环。
（3）、仪表接头的标准 连接仪表管的管径主要有英制和公制两种标准 连接仪表的螺纹主要有NPT和ISO两种标准 管接头主要分为公制和英制两种标准。仪表管接 头管径公制的外径有：2、3、4、6、8mm等型号。 英制的仪表管接头广泛的在平台上应用，而我们 常用的英制仪表管接头管径有： 1/4、3/8、1/2、3/4、 1英寸等。
在实际应用中英制与公制之间管径和接
头不能混用，但两者之间差别很小。所以 在制造时厂家会把所有公制管接头的螺母 上多加一圈边（如左图），而英制的却没 有（如右图）。
仪表连接的螺纹NPT：美国标准管螺纹，它分为 锥螺纹（NPT）和平螺纹（ST）两种 。 锥螺纹（NPT）：其螺纹的角度为60°，螺距以 每英寸多少牙计算，螺纹的牙根和牙顶是锥形的，螺 纹的斜度角为1 °47′，如1/4″，即内管径为1/4″。
仪表接头第二次安装时的标准一样，只需上紧到第一 次安装的位臵即可。对于已经上紧过的管接头，在拆下前 请做好螺帽与接头之间位臵的记号，在重新安装时，首先 用手将螺帽上紧，再用扳手将螺帽上到原来的位臵即可。 对于重复拆装多次的管接头，可以在螺帽上到原位臵后， 再旋转10°～ 20°（不超过六角螺帽一面的1/3，即不超 过B处）。
ISO 228/1（RS） ：其螺纹的角度为55° ，螺距以每英寸多少 牙计算，螺纹的牙根和牙顶是圆的，螺纹的斜度角为 0，如管接头 型号为1/4″ ，即内管径为1/4″的RS型管接头。
注意事项 NPT和ISO 7/1（RT） 都是倾斜度1 °47′ 的锥管螺纹，但由于 螺纹齿形的角度不同，不能混用。 Straight（ST）与ISO 228/1（RS）都是 平螺纹，但由于螺纹齿形不同，也不 能混用。

初次安装方法
Swagelok 管接头的安装可分为 fēn wéi 容易的三步:
1.将卡套管 tào ɡuǎn 完全插入接头内,并且插到底
管子端面需要进行处理 如去毛刺、平口等 ,因为表面 粗糙度对于适当的密封是非常重要的，当管子表面有压 痕、刮痕、突起 tūqǐ 或其他的表面缺陷时,都将难以密封, 特别是在气体系统中， 管子必须插到底， 两卡套缺一不可,并前后不能装反， 不能转动本体,应该夹住本体并转动螺母， 螺母旋转一又四分之一转即可,旋转不够安装不到位,过 度旋转会破坏螺纹并影响复装次数， 在系统加压时,切勿进行装配和拧紧接头，
管接头的再安装 ānzhuāng 注 意事项
1.拆下前做好螺帽与接头之间的位置得记号 2.用手将螺帽上紧,再用扳手将螺帽上到原来的位置即可 3.重复拆装多次的管接头,可以 kěyǐ 在螺帽上到原位置后,再旋转10°~20°

格兰头(cable gland)
阿依蒂尔格兰头最近新项目报材料，厂长说别报防爆挠管了，报格兰头吧，这个好使。
那么，大家知道用格兰头是怎么连接的吗？格兰头也叫电缆密封接头, 和仪表是螺纹连接, 然后用橡胶圈把电缆锁死.格兰头Cable gland（又名电缆防水接头、电缆固定头Cable fixed head和电缆接头Cable joint）广泛应用于机械设备电气、船舶电气、防蚀设备的电线电缆的固定和保护。
主要作用是电缆的紧固与密封。
紧固是指通过格兰锁紧电缆，使电缆不产生轴向位移与径向的旋转，这样保证电缆的连接正常。
密封是指常说的IP防护，即防尘防水，至于格兰的防护等级要看各厂家格兰的结构。
最高可达IP68。
还有一些特殊场所使用的格兰，如屏蔽的电缆防水接头，适用带有屏蔽层的电缆；适用于铠装电缆的铠装电缆防水接头；适用于矿井等危险区域的防爆电缆防水接头等。
很多人都觉得格兰头比挠性管好使首先要确定一下这个接头是用在哪里的？是用在仪表侧还是接线箱侧？仪表侧我们一般采用连续性连接（非铠装电缆），如果是铠装电缆可以采用裸露连接，非铠装电缆，需配置带密封接头的挠性管。
接线箱侧，一般也采用连续性连接，如果是非铠由于装置仪表通过挠性管进水，造成停车，已经全部更换为双密封不锈钢格兰接头，用阿依蒂尔格兰头，安全可靠，质量第一。
挠性管是没有格兰头可靠的，即是质量再好的挠性管，2～3年也会锈蚀、老化。
挠性管进水导致仪表失灵在装置中很常见的，一般有几类：1、挠性管锈蚀老化，雨水进入。
2、雨水沿仪表桥架内进入，通过穿线管流入脑型管到仪表；3、一些隐蔽工程，穿线管埋在地下，到地面后通过脑型管连接仪表，这样下雨时，地下穿线管内雨水无法排出，通过脑型管进入仪表，导致仪表失灵。
以上都是血的教训啊，所以找合适和时机，把装置内挠性穿线管都换成阿依蒂尔格兰头吧。
格兰头也就是电缆夹紧密封接头，他与挠性管的作用是不一样的，格兰头的作用主要是起夹紧密封电缆，而挠性管的作用主要是保护电缆。

仪表接头螺纹简介
螺纹简介
螺纹有连接和密封作用，普遍应用于小口径管道连接中，螺纹的种类很多，最经常使用的螺纹如下。
1．NPT——美国标准管螺纹
NPT（National Pipe Tapered）螺纹是按美国标准ANSI B生产。
表示方式：公称直径+螺纹代号NPT，例如：3/8”NPT
2．ISO 7/1 标准锥管螺纹
ISO 7/1 标准管螺纹指按ISO 7/1生产的螺纹，等同于DIN 2999, BS21, JIS B0203标准的螺纹。
表示方式：螺纹代号+公称直径，例如：R1/4”（BSPT外螺纹），Rc1/4”（BSPT内螺纹），ZG1/4”，PT1/4”。
3．ISO 228/1标准圆柱管螺纹
ISO 228/1标准圆柱管螺纹等同于BS 2779，JIS B0202标准的螺纹。
表示方式：螺纹代号+公称直径，例如：Rp1/4”，G1/4”，PF1/4”。
4．美国统一螺纹
美国统一螺纹（Unified Screw Thread）是按美国标准ANSI 生产.
表示方式：螺纹实际外径+每英寸螺纹牙数+螺纹代号，例如：3/8-24UNF，5/1 6-28UN，3/8-16 UNC，其中UNF表示细螺纹，UNC表示粗螺纹，UN表示常规螺纹。
5．公制螺纹（ISO 261）
公制螺纹是按ISO 261或ANSI 标准生产的螺纹。
表示方式：螺纹代号+实际直径*牙距，例如：M10*1，M14*，M22*。
