摘要
Abstract
High frequency welding, hot stretch reducing, full body heat treatment and hot straightening process was adopted to produce 80 and 110 grade SEW high collapse resistance oil casing. The mechanical properties and corrosion resistance properties of SEW high collapse resistance oil casing were tested. The results showed that the dimensional accuracy, residual stress and collapse resistance of SEW high collapse resistance oil casing are much better than seamless high collapse resistance oil casing. Moreover, adopting the above process well solves the problems of low impact toughness and poor corrosion resistance of weld zone. Therefore, under the same condition, using SEW high collapse resistance oil casing can solve the low collapse resistance of seamless high collapse resistance oil casing.关键词
