生產工藝:
①熱軋無縫鋼管主(zhu)要生(sheng)產工(gong)序(xu)(△主(zhu)要檢驗(yan)工(gong)序(xu)):
管(guan)(guan)坯(pi)準備及(ji)檢(jian)查△→管(guan)(guan)坯(pi)加熱→穿孔→軋管(guan)(guan)→鋼(gang)管(guan)(guan)再加熱→定(減)徑(jing)→熱處理△→成品管(guan)(guan)矯直→精整→檢(jian)驗△(無損、理化、臺檢(jian)) →入庫
②冷軋(ya)(拔)無縫(feng)鋼(gang)管(guan)主(zhu)要生產工序:
坯料準(zhun)備→酸洗(xi)潤滑→冷軋(拔)→熱處(chu)理→矯直→精整→檢驗
