摘要: 介紹了國(guó)外長(zhǎng)輸管線用ERW直縫焊管、SAW螺旋焊管的生產(chǎn)工藝及質(zhì)量要求。指出國(guó)內(nèi)引進(jìn)的該類焊管機(jī)組必須開發(fā)自動(dòng)檢測(cè)控制技術(shù)，采取可靠的質(zhì)量控制手段，以提高大直徑長(zhǎng)輸管線管的產(chǎn)品質(zhì)量。Abstract: Described in the paper are the manufacturing processes and quality criteria employed abroad for ERW straight weld-pipes and SAW spiral-weld pipes used for long-distance transport purpose pipelines. The co-authors hold that to improve the product quality of home-made long-distance transport-purpose line pipes, it is necessary to develop auto-inspection-control techniques and to employ reliable quality control measures for imported weld-pipe mills with similar processes.
