螺旋埋弧焊管生產注意事項

日期:2020-02-28

螺旋埋弧焊管在生產過程中,需要注意一系列事項。除以下試驗項目外,根據API標準等相關標準和部分用戶的特殊要求,還需要對鋼材、鋼管等進行破壞性試驗,包括對進廠原材料的理化性能進行抽樣、100%鋼的外觀檢驗。

螺旋埋弧焊管生產注意事項

A、 涂油標識:鋼材合格后涂油防腐,并按用戶要求進行標識。

B、 平銑:先將扁鋼砧機使原卷曲,再通過邊銑機進行雙面鋼銑,以滿足板寬、板邊平行度和槽形的要求。

C、 剪切成型:鋼板生產線沿螺旋外緣卷曲成管。

D、 對接切割:雙面埋弧焊接采用先進技術進行預焊、內焊、外焊。焊接鋼管采用等離子焊腳切割至規定長度。
