鋼管的公稱直徑外徑和壁厚

1、1. 總則1.0.1 本標準規(guī)定了石油化工企業(yè)用DN10-DN2000的碳鋼素鋼、合金鋼、奧氏體不銹鋼無縫鋼管及焊接鋼管的尺寸系列。10.2 本標準適用于石油化工企業(yè)中的一般鋼制管道。本標準不適用于儀表用管道。1.0.3 本標準代替鋼管的公稱直徑、外徑和壁厚（BA3-4-1-92）。2. 引用標準GB8163 輸送液體用無縫鋼管GB9948 石油裂化用無縫鋼管GB6479 化肥設備用高壓無縫鋼管GB5130 高壓鍋爐用無縫鋼管GB/T14976 流體輸送用不銹鋼無縫鋼管GB/T3091 低壓流體輸送用鍍鋅焊接鋼管GB/T3092 低壓流體輸送用焊接鋼管GB/T14980 低壓流體輸送用大直徑電

4、墊片系列。DN300可選用SH標準，也可選用其他相配套的標準。 d） 表表中DN300的鋼管尺寸，亦可與國外某些標準（例如ANSI標準）配套使用。但如果管子為國外訂貨，則其外徑和壁厚應符合國外有關標準。3.0.2 有縫鋼管DN6DN150按低壓流體輸送用鍍鋅焊接鋼管（GB/T3091-93)和低壓流體輸送用焊接鋼管（GB/T3092-93）選用。DN150500按低壓流體輸送用大直徑電焊鋼管（GB/T14980-94）選用。4. 鋼管尺寸系列4.0.1 奧氏體不銹鋼無縫鋼管尺寸和理論質量見表。4.0.2 碳素鋼、合金鋼無縫鋼管的尺寸和理論質量見表。4.0.3 奧氏體不銹鋼焊接鋼管的尺寸和理論質
