Abstract
Adopting a new process of high frequency welding(HFW)+hot stretch reducing (referred to as SEW)to conduct trial produce for oil casing billet,then the flattening tests were carried out respectively for sample pipe before and after hot stretch reducing. The results indicated that flattening tests all qualified, even if the sample is crushed to the lining joint, the specimens with tiny crack in weld are few. This showed that the plastic deformation capacity of weld is improved significantly, achieves the purpose of welded pipe seamless.关键词
