摘要:
采用“HFW+热张力减径+整管热处理+热矫直”工艺开发了80及110钢级SEW高抗挤套管,并对开发的SEW高抗挤套管进行了力学性能和抗腐蚀性能测试。结果表明,同无缝高抗挤套管相比,SEW高抗挤套管在尺寸精度、残余应力及抗外压挤毁性能方面具有较大的优势,且采用上述工艺,较好地解决了焊缝冲击韧性低及抗腐蚀性能差的问题。因此,在其他条件相同时,采用SEW高抗挤套管可解决无缝高抗挤套管带来的抗挤强度不足问题。
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.
