水电安装钢管公称直径、外径、壁厚和理论重量表

1、1. 总则 本标准规定了石油化工企业用DN10-DN2000的碳钢素钢、合金钢、奥氏体不锈钢无缝钢管及焊接钢管的尺寸系列。10.2 本标准适用于石油化工企业中的一般钢制管道。本标准不适用于仪表用管道。 本标准代替钢管的公称直径、外径和壁厚（BA3-4-1-92）。2. 引用标准GB8163 输送液体用无缝钢管GB9948 石油裂化用无缝钢管GB6479 化肥设备用高压无缝钢管GB5130 高压锅炉用无缝钢管GB/T14976 流体输送用不锈钢无缝钢管GB/T3091 低压流体输送用镀锌焊接钢管GB/T3092 低压流体输送用焊接钢管GB/T14980 低压流体输送用大直径电焊钢管SY/T503

3、布代替SHJ405-89并开始实施.。考虑国内目前钢管及管道法兰组件生产和供应的实际情况。全部执行该标准尚有一定困难。本标准基本按照SH3405-96的规定，但作了若干修改，主要有； a） 公称直径DN350DN1000钢管的外径仍按我院现行规定编制，以便于与机械部法兰（JB/T81-94JB/T86-94）配套连接。 b）考虑到在老厂改造设计中仍有可能选用小外径钢管，本标准补充列入了外径钢管系列，但不推荐选用。 c） 本标准列出了中国石化总公司标准石油化工企业钢管尺寸系列（SH3405-96），当选用该系列时，DN350须选用与SH相配套的的法兰、管件、紧固件和垫片系列。DN300可选用SH

4、标准，也可选用其他相配套的标准。 d） 表表中DN300的钢管尺寸，亦可与国外某些标准（例如ANSI标准）配套使用。但如果管子为国外订货，则其外径和壁厚应符合国外有关标准。 有缝钢管DN6DN150按低压流体输送用镀锌焊接钢管（GB/T3091-93)和低压流体输送用焊接钢管（GB/T3092-93）选用。DN150500按低压流体输送用大直径电焊钢管（GB/T14980-94）选用。4. 钢管尺寸系列 奥氏体不锈钢无缝钢管尺寸和理论质量见表。 碳素钢、合金钢无缝钢管的尺寸和理论质量见表。 奥氏体不锈钢焊接钢管的尺寸和理论质量见表。 碳素钢、合金钢焊接钢管的尺寸和理论质量见表。 小外径系列碳素

5、钢、合金钢、奥氏体不锈钢无缝钢管的尺寸和理论质量见表。 有缝钢管的尺寸和理论质量见表表表。 中国石化总公司标准SH3046的钢管尺寸系列见附录A。 钢管的每米理论质量可按下式计算： M=0.02466t（D-t）（）式中： M钢管质量，kg/m t钢管壁厚，mm D钢管外径，mm对于奥氏体不锈钢钢管，按上式计算后再乘以1.015。精确计算时，各种奥氏体钢的密度见GB/T14976-94中的表5。招聘代理，月收入上万元 qq：492216701 旺旺：hejinhai008表 奥氏体不锈钢无缝钢管尺寸和理论质量公称外径壁厚及理论质量直径sch5ssch10ssch20ssch40ssch80sD
