摘要:
对采用高强度卷板、高频焊焊接(HFW)工艺开发的120 ksi钢级小油管,开展了母材和焊缝的理化性能、氢致开裂、应力腐蚀等试验分析研究。结果表明:120 ksi小油管样品理化性能控制较好,但氢致开裂试验均出现大量裂纹,其裂纹敏感率、裂纹长度率、裂纹厚度率均较高,同时管材抗应力腐蚀性能较差,样管在66%σs应力加载下出现大量裂纹或断裂,表明普通120 ksi强度级别的油管无法满足抗硫化氢腐蚀要求。
Abstract:
The physical and chemical properties, hydrogen?nduced cracking, stress corrosion of the base material and weld of 120 ksi steel grade small tubing developed by high strength coil and high frequency welding (HFW) process were studied. The physical and chemical properties of 120 ksi small tubing samples are well controlled, but there are a lot of cracks in hydrogen induced cracking tests, and the crack sensitivity rate, crack length rate and crack thickness rate are high. The stress corrosion resistance of the pipe is poor, and the sample pipe has a lot of cracks or fractures under 66% σs stress loading. It indicates that the ordinary 120 ksi strength level of tubing can not meet the requirements of hydrogen sulfide corrosion resistance.
