1、钢管公称直径、外径、壁厚和理论重量表钢管公称直径、外径、壁厚和理论重量表依据给水排水制图标准（GB/T50106-2001）第2.4节管径中有关规定：1、水煤气输送钢管（镀锌和非镀锌）、铸铁管等管材，管径标注为DN（mm）；2、无缝钢管、焊接钢管（直缝或螺旋缝）、铜管、不锈钢管等管材，管径标注为外径Dx壁厚；3、钢筋混凝土（或混凝土）管、陶土管、耐酸陶瓷管等管材，管径标注为d；4、塑料管材，管径宜按产品标准的方法标注；当设计用DN标注管径时，应有DN与相应产品规格对照表。塑料管管径按产品标准的方法标注一般以外径表示，如UPUC管标注为de，HDPE管标注为De。1.总则1.0.1本标准规定了石

2、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。1.0.3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/T5037普通流体输送管道用螺旋埋弧焊钢管SH

4、钢管尺寸系列已颁布代替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DN350 DN1000 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。DN30
