| 摘 要： | 本文通过１０ＣｒＭｏ９１０钢大口径厚壁管道高温模拟试验证实，焊后热处理是一个短时超高温运行过程，它使１０ＣｒＭｏ９１０钢管接头组织提前老化，显著降低了接头的持久寿命。试验结果表明，传统的焊后热处理工序应当取消。

| Abstract: | In this paper, tests have conducted upon the thick-wall large-sized pipe joints made of 10CrMo910 steel with high-temperature imitation technique. Results have shown that the post-welding heat treatment is a short-time process under superhigh-temperature, which causes premature aging in joints and, therefore, reducing their long-term life. Consequently, it is recommendable to cancel the operation of post-welding heat treatment. |
