一般的無(wú)縫鋼管的生產(chǎn)工藝可以分為冷拔與熱軋兩種，冷軋無(wú)縫鋼管的生產(chǎn)流程一般要比熱軋要復(fù)雜，管坯首先要進(jìn)行三輥連軋，擠壓后要進(jìn)行定徑測(cè)試，如果表面沒(méi)有響應(yīng)裂紋后圓管要經(jīng)過(guò)割機(jī)進(jìn)行切割，切割成長(zhǎng)度約一米的坯料。然后進(jìn)入退火流程，退火要用酸性液體進(jìn)行酸洗，酸洗時(shí)要注意表面是否有大量的起泡產(chǎn)生，如果有大量的起泡產(chǎn)生說(shuō)明鋼管的質(zhì)量達(dá)不到相應(yīng)的標(biāo)準(zhǔn)。外觀上冷軋無(wú)縫鋼管要短于熱軋無(wú)縫鋼管，冷軋無(wú)縫鋼管的壁厚一般比熱軋無(wú)縫鋼管要小，但是表面看起來(lái)比厚壁無(wú)縫鋼管更加明亮，表面沒(méi)有太多的粗糙，口徑也沒(méi)有太多的毛刺。
