焊han接jie鋼gang管guan也ye稱cheng焊han管guan
，是shi用yong鋼gang板ban或huo帶dai鋼gang經jing過guo卷juan曲qu成cheng型xing後hou焊han接jie製zhi成cheng的de鋼gang管guan。焊han接jie鋼gang管guan生sheng產chan工gong藝yi簡jian單dan，生sheng產chan效xiao率lv高gao
，品pin種zhong規gui格ge多duo
，設she備bei資zi少shao
，但dan一yi般ban強qiang度du低di於yu無wu縫feng鋼gang管guan。

隨sui著zhe優you質zhi帶dai鋼gang連lian軋zha生sheng產chan的de迅xun速su發fa展zhan以yi及ji焊han接jie和he檢jian驗yan技ji術shu的de進jin步bu
，焊han縫feng質zhi量liang不bu斷duan提ti升sheng，焊han接jie鋼gang管guan的de品pin種zhong規gui格ge日ri益yi增zeng多duo，並bing在zai越yue來lai越yue多duo的de領ling域yu代dai替ti了le無wu縫feng鋼gang管guan。焊han接jie鋼gang管guan按an焊han縫feng的de形xing式shi分fen為wei直zhi縫feng焊han管guan和he螺luo旋xuan焊han管guan。按an生sheng產chan方fang法fa分fen類lei：工藝分類-電弧焊管
，電阻焊管，（高頻，低頻）氣qi焊han管guan，爐lu焊han管guan。直zhi縫feng焊han管guan生sheng產chan工gong藝yi簡jian單dan，生sheng產chan效xiao率lv高gao，成cheng本ben低di

，發fa展zhan較jiao快kuai。螺luo旋xuan焊han管guan的de強qiang度du一yi般ban比bi直zhi縫feng焊han管guan高gao

，焊han縫feng長chang度du增zeng加jia30~100%
，而且生產速度較低。
