美标与国标管道壁厚对照表

美标与国标管道壁厚对照表

美标与国标管道壁厚对照表
美标(ASME标准)和国标(GB标准)在管道壁厚方面有一些差异,因此制定对照表时需要考虑不同标准之间的等效关系。

以下是一个简化的美标与国标管道壁厚对照表的示例,供参考:
需要注意的是,美标和国标使用不同的单位,美标通常使用英寸(inch),而国标通常使用毫米(mm)。

在对照表中,将美标的管道壁厚以英寸为单位,与国标的管道壁厚以毫米为单位进行了简单的对照。

此表格是一个概念性的对照表,实际应用时需要更详细的参考相关标准文件,以确保准确的对照。

管道壁厚对照表的编制应该根据具体的项目和要求,确保所使用的材料和规格符合相关标准和法规的要求。

建议在实际工程中寻求专业工程师的帮助,以确保管道设计和施工的合规性和安全性。

ASMEB管道壁厚自动计算

ASMEB管道壁厚自动计算

ASMEB管道壁厚自动计算ASMEB(美国机械工程师学会标准编制)中管道壁厚自动计算方法主要参考ASMEB31校准的公式,用于确定管道壁厚以满足设计要求。

其中,ASMEB31.3适用于化工、石化、石油、天然气等行业的管道系统设计,ASMEB31.1适用于电站、供热行业等的管道系统设计。

t=f*P*d/(2*S-1.2*P)其中,t为管道壁厚,单位为英寸(inch);f为设计系数,根据管道材料和温度使用不同的数值;P为设计压力,单位为psi(磅力/平方英寸);d为管道外径,单位为英寸;S为管道的焊接接头系数。

根据ASMEB31.1中的公式,管道壁厚计算公式为:t=(P*d)/(2*S-1.2*P)其中,t为管道壁厚,单位为英寸;P为设计压力,单位为psi(磅力/平方英寸);d为管道外径,单位为英寸;S为焊接接头的强度系数,根据管道的接头类型不同使用不同的数值。

这些公式的计算方法都是基于安全性要求,以确保管道在承受设计压力时不会发生破裂或泄漏。

在进行计算时,需要首先确定设计压力P,考虑到操作条件、流体性质和管道系统中可能发生的压力峰值。

然后确定管道的焊接接头系数S,这需要根据具体的焊接接头类型进行查找相应的数值。

最后,确定管道的外径d和材料种类,选择适当的设计系数f。

需要注意的是,以上公式只是ASME标准中的一种方法,实际应用时还需要考虑到其他因素,如温度和环境条件等。

此外,在进行管道壁厚计算时,还需要遵循其他相关的ASME标准和规范,并在计算过程中进行合理的安全裕度考虑。

通过自动计算程序,可以将上述公式编写成计算脚本,通过用户输入相关参数,完成管道壁厚的自动计算。

这样能够提高计算速度和精度,避免人工计算中可能出现的误差。

同时,也方便了设计人员进行快速设计和修改,提高了工作效率。

asme筒体壁厚计算公式

asme筒体壁厚计算公式

asme筒体壁厚计算公式ASME筒体壁厚计算公式。

ASME(美国机械工程师协会)是一个国际性的专业工程师协会,致力于推动机械工程领域的发展和创新。

在压力容器设计中,ASME提供了一系列的标准和规范,其中包括了对于筒体壁厚的计算公式。

本文将探讨ASME筒体壁厚计算公式的相关内容,并对其进行详细的解析和应用。

在压力容器设计中,筒体是一个常见的结构元件,其主要作用是承受内部介质的压力。

为了确保筒体在工作状态下能够安全可靠地工作,需要对其进行合理的壁厚设计。

ASME提出了一种常用的筒体壁厚计算公式,即根据设计压力、材料强度和容器尺寸等参数来确定筒体壁厚。

ASME筒体壁厚计算公式的一般形式如下:t = PR / (SE 0.6P)。

其中,t表示筒体壁厚,P表示设计压力,R表示筒体内径,S表示材料的允许应力,E表示材料的弹性模量。

在这个公式中,设计压力是决定筒体壁厚的重要参数之一。

设计压力是指在设计条件下,容器内部介质的最大允许压力。

通常情况下,设计压力是由工艺条件、安全因素和法规要求等综合考虑而确定的。

对于不同的设计压力,筒体壁厚的要求也会有所不同。

另一个影响筒体壁厚的因素是材料的允许应力。

材料的允许应力是指在设计条件下,材料可以承受的最大应力值。

通常情况下,材料的允许应力是由材料的屈服强度、拉伸强度和安全系数等参数综合确定的。

不同的材料具有不同的允许应力值,因此在选择材料时需要充分考虑其强度特性。

除了设计压力和材料的允许应力外,筒体壁厚还受到筒体内径和材料的弹性模量的影响。

筒体内径是指筒体的直径尺寸,通常情况下,筒体内径越大,所需的壁厚也会越大。

材料的弹性模量是指材料在弹性阶段的应力-应变关系中的斜率,它是材料的刚度指标,对于筒体壁厚的计算也具有重要的影响。

在实际的工程设计中,根据ASME提供的筒体壁厚计算公式,可以通过对设计压力、材料的允许应力、筒体内径和材料的弹性模量等参数进行合理的选择和计算,来确定合适的筒体壁厚。

American Standards Association authorized the organization of a Sectional Committee on Standardization of Dimensions and Material of Wrought Steel and Wrought Iron Pipe and Tubing for the purpose of unifying the standards of these commodities in force in this country.The American Society for Testing and Materials and The American Society of Mechanical Engineers were designated as sponsors,and the first meeting of the Sectional Committee was held in Pittsburgh,Pennsylvania,on May18,1928.The dimensions of commercial pipe in general use in the United States at the time conformed rather generally to those recommended by the ASME Committee on Standard Pipe and Pipe Threads published in1886(ASME Transactions,Vol.VIII,p.29).On these standards an enormous industry has been built and the satisfactory use of this product proves the soundness of the original design and specification.Increasingly severe service demands at the time of the Committee’s organization had been met by using the nearest available pipe or tubing for heavier sections such as casing,mechanical tubing,etc.,with resulting uneconomical multiplicity of wall thicknesses.Subsequently,the Committee,with the cooperation of the industry,made a survey of existing practice as the logical starting point for the development of an American Standard.From this survey,a table was designed to provide a selection of wall thicknesses of pipe to cover the power piping requirements of industry where strength to resist internal pressure governs selection and was later expanded to include pipe diameters and thicknesses used in other industries.The original intent of the Committee was to establish a system of Schedule Numbers for pipe size/wall thickness combinations which would have an approximately uniform relationship equal to1000times the P/S expression contained in the modified Barlow formula for pipe wall thickness as defined in the Appendix to this standard.The resulting Numbers departed so far from existing wall thicknesses in common use that the original intent could not be accomplished.The Schedule Numbers were then adopted strictly as a convenient designation system for use in ordering.In all cases,the designer must base his selection on the rules and allowable stresses set by the code which governs his particular construction.The table is dimensionally complete for all sizes and wall thicknesses within its scope,but some of the larger,heavier wall sections are beyond the capability of seamless mill production and must be obtained from forged and bored billets or other sources.The first issue of this standard was given with the designation American Standard“tentative”by the American Standards Association in November1935.Subsequent slight revisions to Table 1and the footnotes of the dimensional tables were approved and the ASA changed the designation to American Standard;the date of ASA approval was April28,1939.Further revisions were made by the Sectional Committee.The list of specifications in Table1 was revised where necessary and slight revisions in wall thicknesses of some of the large sizes of the heavy schedules were made where P/S values were out of line.It was the hope in1939that the designation of pipe used commercially by all industry as Standard weight,Extra-Strong,and Double Extra-Strong would gradually be replaced by Schedule Number designation.However,owing to customs of over50years’standing,demand and produc-tion of pipe to these traditional dimensions is undiminished.Consequently,in response to a demand from users,accepted practice for dimensions and weights of commercial wrought steel and welded wrought iron pipe were added.These changes were designated an American Standard on February23,1950.Subcommittee No.1was reorganized in1957.In addition to necessary editorial changes,a simplified format was selected for the tables of weights and dimensions so as to include and identify the sizes and weights of API Standards5L and5LX.These changes to the standard were approved and it was designated an American Standard on December21,1959.The standard was revised in1969.A uniform method to calculate the plain end weight of steel pipe was included,and minor adjustments were made in the tabulated weights of steel pipe inivTable2to conform to this new method.Additional sizes and thicknesses of steel pipe that had come into common use were also added to Table2.Inasmuch as API Standard5L no longer included wrought iron pipe,reference to this API Standard was deleted from Table3.These changes to the standard were approved and it was designated an American National Standard on February3,1970.Further revisions were made to the standard in1975.Additional sizes and thicknesses of steel pipe that had been added to API specifications were added to Table2.Table3,Dimensions and Weights of Welded Wrought Iron Pipe,was deleted in its entirety,since wrought iron pipe is no longer produced.These changes in the standard were approved and it was designated an American National Standard on June5,1975.The standard was revised in1978to include SI metric dimensions.The outside diameter and wall thicknesses were converted to millimeters by multiplying the inch dimensions by25.4. Outside diameters larger than16in.were rounded to the nearest millimeter,and outside diameters 16in.and smaller were rounded to the nearest0.1mm.Wall thicknesses were rounded to the nearest0.01mm.These converted and rounded SI metric dimensions were added to Table2.A formula to calculate the SI metric plain end mass,in kilograms per meter,using SI metric diameters and thicknesses was added to section5.The SI metric plain end mass was calculated and was added to Table2.These changes in the standard were approved and it was designated an American National Standard on July18,1979.Further revisions were made in1984.The ANSI designations,which are no longer in use,were deleted from Table1,and the list of specifications was revised to agree with current ASTM and API specifications.Additional sizes and thicknesses which had been added to API specifications were added to Table2.That edition was approved as an American National Standard on August 19,1985.The next edition included additional wall thicknesses and was approved by the American National Standards Institute on August24,1995.The1996edition contained revisions to Table2,adding pipe sizes,changing some plain end weights and masses,identifying metric pipe by the dimensionless designator DN,and eliminating the API Specification column.The1996edition was approved as an American National Standard on September23,1996.The2000edition contained revisions to Table2to include the revised density for steel incorpo-rated into Section5previously.Table1was deleted and other editorial changes to Sections1,2, 3,5,8,and9were made.The2000edition was approved as an American National Standard on December1,2000.The current edition contains revisions to Section5and Table1.It corrects the equation for nominal plain end weight.It adds the missing DN schedule numbers in Table1.This edition was approved as an American National Standard on June23,2004.vASME B32COMMITTEEMetal and Metal Alloy Wrought Mill Product Nominal Sizes (The following is the roster of the Committee at the time of approval of this Standard.)OFFICERSJ.A.Gruber,ChairJ.H.Karian,SecretaryCOMMITTEE PERSONNELF.M.Christensen,F.M.Christensen Metallurgical Consulting,Inc.A.Cohen,Arthur Cohen&AssociatesJ.A.Gruber,Wheatland Tube Co.W.N.Holliday,LTV Steel Co.L.T.Ingels,American Gas Association,Inc.J.H.Karian,The American Society of Mechanical EngineersK.O.Kverneland,Kok Metric Co.A.R.Machell,Jr.P.Pollak,Aluminum Association,Inc.R.N.RauviASME B36.10M-2004 WELDED AND SEAMLESS WROUGHT STEEL PIPE1SCOPEThis Standard covers the standardization of dimen-sions of welded and seamless wrought steel pipe for high or low temperatures and pressures.The word pipe is used,as distinguished from tube,to apply to tubular products of dimensions commonly used for pipeline and piping systems.Pipe NPS12(DN300) and smaller have outside diameters numerically larger than their corresponding sizes.In contrast,the outside diameters of tubes are numerically identical to the size number for all sizes.2SIZEThe size of all pipe is identified by the nominal pipe size.The manufacture of pipe NPS1⁄8(DN6)to NPS12 (DN300),inclusive,is based on a standardized outside diameter(OD).This OD was originally selected so that pipe with a standard OD and having a wall thickness that was typical of the period would have an inside diameter(ID)approximately equal to the nominal size. Although there is no such relation between the existing standard thickness—OD and nominal size—these nominal sizes and standard ODs continue in use as ‘‘standard.’’The manufacture of pipe NPS14(DN350)and larger proceeds on the basis of an OD corresponding to the nominal size.3MATERIALSThe dimensional standards for pipe described here are for products covered in ASTM specifications.4WALL THICKNESSThe nominal wall thicknesses are given in Table1.5WEIGHTSThe nominal weights of steel pipe are calculated val-ues and are tabulated in Table1.The nominal plain end weight,in pounds per foot,is calculated using the following formula:W pe p10.69(D−t)twhere1D p outside diameter to the nearest0.001in.(thesymbol D is to be used for OD only in mathe-matical equations or formulas)W pe p nominal plain end mass,rounded to the near-est0.01lb/ftt p specified wall thickness,rounded to the near-est0.001in.The nominal plain end mass,in kilograms per meter, is calculated using the following formula:W pe p0.0246615(D−t)twhereD p outside diameter to the nearest0.1mm foroutside diameters that are16in.(406.4mm)and smaller and to the nearest1.0mm foroutside diameters larger than16in.(406.4mm)(the symbol D is to be used for OD onlyin mathematical equations or formulas)W pe p nominal plain end mass,rounded to the near-est0.01kg/mt p specified wall thickness,rounded to the near-est0.01mm6PERMISSIBLE VARIATIONSVariations in dimensions differ depending upon the method of manufacture employed in making the pipe to the various specifications available.Permissible varia-tions for dimensions are indicated in each specification. 7PIPE THREADSUnless otherwise specified,the threads of threaded pipe shall conform to ANSI/ASME B1.20.1,Pipe Threads,General Purpose(Inch).Schedules5and10wall thicknesses do not permit threading in accordance with ANSI/ASME B1.20.1.8WALL THICKNESS DESIGNATIONSThe wall thickness designations Standard,Extra-Strong,and Double Extra-Strong have been commer-cially used designations for many years.As explained in the Foreword,the Schedule Numbers were subsequently added as a convenient designation for use in ordering pipe.Standard and Schedule40are identical for up to NPS10(DN250),inclusive.All larger sizes of StandardASME B36.10M-2004WELDED AND SEAMLESS WROUGHT STEEL PIPEhave3⁄8in.(9.53mm)wall thicknesses.Extra-Strong and Schedule80are identical for up to NPS8(DN200), inclusive.All larger sizes of Extra-Strong have1⁄2in. (12.70mm)wall thicknesses.Pipe of sizes and wall thicknesses other than those of Standard,Extra-Strong,and Double Extra-Strong,and Schedule Number were adopted from API Specification5L.It was not considered practical to establish Schedule Numbers or new designations for them.9WALL THICKNESS SELECTIONWhen the selection of wall thickness depends primar-ily upon capacity to resist internal pressure under given2conditions,the designer shall compute the exact value of wall thickness suitable for conditions for which the pipe is required,as prescribed in detail in the ASME Boiler and Pressure Vessel Code,ASME B31Code for Pressure Piping,or other similar codes,whichever gov-erns the construction.A thickness shall be selected from Table1to suit the value computed to fulfill the condi-tions for which the pipe is desired.WELDED AND SEAMLESS WROUGHT STEEL PIPE ASME B36.10M-2004Table1Dimensions and Weights of Welded and Seamless Wrought Steel PipeIdentificationCustomary Units SI

管道壁厚计算公式

管道壁厚计算公式

管道壁厚计算公式
1.内压力:
管道内部的流体压力是计算管道壁厚的主要因素之一、一般情况下,管道壁厚的计算公式如下:
t=(P*D)/(2*S*E-0.8*P)
其中,t为管道的壁厚(单位为mm),P为管道内部的设计压力(单位为MPa),D为管道的外径(单位为mm),S为管道材料的允许应力(单位为MPa),E为管道材料的弹性模量(单位为MPa)。

2.外压力:
管道外部的环境压力也会对管道壁厚的计算产生影响。

通常情况下,管道外部的设计压力会小于内部的设计压力,因此可采用以下公式计算管道的壁厚:
t=(P*D)/(2*S*E+0.4*P)
其中的符号意义同上。

3.弯曲应力和压力脉动:
管道在运行过程中可能会受到弯曲应力和压力脉动的影响,这些因素也需要考虑到管道壁厚的计算中。

一般而言,管道壁厚的计算公式会根据具体的弯曲应力和压力脉动的情况来确定。

4.温度应力:
管道在不同温度下会发生膨胀和收缩,从而产生应力,也需要考虑到管道壁厚的计算中。

一般而言,计算管道壁厚时需要根据具体的温度条件来确定。

5.其他因素:
除了以上几个主要因素外,还有一些其他因素也需要考虑到管道壁厚的计算中。

例如,管道的使用年限、使用环境等因素也会对管道壁厚的计算产生影响。

综上所述,管道壁厚的计算公式是一个复杂的问题,需要考虑到多个因素的综合影响。

在实际工程中,一般会根据具体的设计条件和材料特性来确定最合适的计算公式,以保证管道的安全性和可靠性。

压力管道设计常用ASME标准

压力管道设计常用ASME标准

一、压力管道设计常用ASME标准这里有两个标准,一个是组件尺寸型式标准(我国也有相应组件形式标准),另一个是材料标准(我国没有对材料形成专门的标准化)。

型式标准规定了组件的型式、系列、尺寸、公差、试验要求,以及该组件可采用的材料标准等。

材料标准规定了适用的对象、原材料(坯料)品种(采用锻轧Wrought或锻件Forged)、化学成分、机械性能、制造工艺(包括焊接)、热处理、无损检查、取样和性能检验、质量证书、标志等。

压力管道的壁厚选择是压力管道设计中最基本和最常见的问题,但是在实际设计过程中却非常混乱,经常出现凭经验估算、乱用SCH表、不经过演算随意套用某些手册数据的现象,还有的认为壁厚越大越好,随意扩大管道壁厚。

管道壁厚选择的不合理,不但给安全带来隐患,而且也造成建设成本的提高和材料的浪费。

加蓬撬块项目设计过程中,需要对压力管道进行壁厚计算、校核,由于该工程压力等级多,计算工作量大。

因此,我们采用Excel表格编写了一个可以自动计算管道壁厚的程序,只需要输入相应的参数,就会自动计算出结果,方便、快速、准确,自动生成计算书。

该工程采用ASME 《工艺管道规范》,是美国机械工程师学会《压力管道规范》ASME B31中的一卷。

工艺管道包含了炼油、化工、制药、纺织、造纸、半导体和制冷工厂,以及相关的工艺流程装置和终端设备中的典型管道。

本规范规定了上述管道在材料、设计、制作、装配、安装、检查、检验和试验的要求。

它适用所有流体的管道,如水、气、蒸汽、液化固体、低温流体等。

一、壁厚计算
(1)当直管壁厚t小于管子外径D的1/6时,根据ASME 《工艺管道规范》采用了如下公式:
T——压力设计壁厚;
P——设计内压(表压);
D——管道外径;
S——材料的许用压力,查表A-1;
E——表A-1A或A-1B所列的质量系数;
Y——从表查的系数,但限于t<D/6和表列的材料。

(2)管道的直管部分所要求的厚度应按公式确定
tm——包括机加工、腐蚀和腐蚀裕量在内的所需最小壁厚;
c——机械裕量(螺纹或沟槽深度)与腐蚀和磨蚀裕量的总和。

对于带螺纹的组件,应采用公称螺纹深度(ASME 的尺寸h或相当的尺寸);对于没有规定公差的机加工表面或槽,应在规定的切削深度上加()的公差。

二、计算实例:
设计参数:设计压力:;设计温度:80℃;材料:A106 ;腐蚀裕量:3mm;公称直径:200mm;
三、计算结果。
