鋼管常用規(guī)格表

1、常用鋼管規(guī)格表管徑應(yīng)以mm為單位，管徑的表達(dá)方式應(yīng)符合下列規(guī)定：1水煤氣輸送鋼管（鍍鋅或非鍍鋅）、鑄鐵管等管材，管徑宜以公稱直徑DN表示；2無(wú)縫鋼管、焊接鋼管（直縫或螺旋縫）、銅管、不銹鋼管等管材，管徑宜以Dxs（外徑邇!厚）表示；3鋼筋混凝土（或混凝土）管、陶土管、耐酸陶瓷管、缸瓦管等管材，管徑宜以內(nèi)徑d表示；4塑料管材，管徑宜按產(chǎn)品標(biāo)準(zhǔn)的方法表示：當(dāng)設(shè)計(jì)均用公稱直徑DN表示管徑時(shí)，應(yīng)有公稱直徑DN與相應(yīng)產(chǎn)品規(guī)格對(duì)照表。建筑排水用硬聚氯乙烯管材規(guī)格用de（公稱外徑）e（公稱壁厚）表示（GB5836.1-92）給水用聚丙烯（PP）管材規(guī)格用de表示（公稱外徑壁厚）公英制單位換算1英寸=25.4
