摘要
Abstract
The welded joint structure of bimetal-lined pipe is complex and is difficult to be welded. Through analysis on pipe end treatment and butt welding procedure for bimetal-lined pipe, it indicated the overlaying was easy to weld but not to be economic comparing with seal welding, it also pointed out that alloy wire butt welding might be used to weld thin wall and small diameter bimetal-lined pipes, while for thick wall and large diameter pipes the buffer layer welding method can be used. Additionally, the existing standards about welding procedure qualification were analyzed in the paper, and the necessity of drafting welding procedure qualification standard about bimetal-lined pipes was emphasized.关键词
