1、无缝钢管公称直径、外径请问：无缝钢管的公称直径和其内径、外径是一回事吗？管子的直径可分为外径、内径、公称直径。管材为无缝钢管的管子的外径用字母。来表示，其后附加外直径的尺寸和壁厚，例如外径为108的无缝钢管，壁厚为5mm,用0 108X5表示，无缝钢管、钢筋混凝土管、铸铁管、镀锌钢管等在设计图纸 中一般采用公称直径来表示，采用 DN表示，公称直径是为了设计制造和维修的方便 人为地规定的一种标准，也称公称通径，是管子（或者管件）的规格名称。管子的公 称直径和其内径、外径都不相等，例如：公称直径为100 mm的无缝钢管有102X5、108X5等好几种，108为管子的外径，5表示管子的壁厚，因此，该

2、钢管的内径为（108 X5-5） =98 mm,但是它不完全等于钢管外径减两倍壁厚之差，也可以说，公称直径 是接近于内径，但是又不等于内径的一种管子直径的规格名称，在设计图纸中所以要 用公称直径，目的是为了根据公称直径可以确定管子、管件、阀门、法兰、垫片等结 构尺寸与连接尺寸，公称直径采用符号 DN表示，如果在设计图纸中采用外径表示， 也应该作出管道规格对照表，表明某种管道的公称直径、壁厚。压力容器常用的是输送流体用无缝钢管（GB8163）。以下是常用无缝钢管公称直径与外径的对照：DN-公称直径外径DN156 22mmDN206 27mmDN256 34mmDN326 42mmDN406 48
