摘要
Abstract
This paper studies the mechanical performance of 26CrMo48VNb seamless pipes under specific heat treatment process conditions.The heat treatment process parameters adopted in the experiment are as follows:The quenching temperature is controlled within the range of 900±10℃,and the quenching heating and holding time is set at 60 minutes.The tempering temperature is 660℃,and the tempering heating and holding time is 100 minutes.Under this process condition,the pipe body elongation rate reaches about 20%,which is significantly higher than the performance level of conventional pipes.In terms of impact toughness,the test results show that the impact energy of a single specimen has increased by 100%compared to the standard specified value,which indicates that the material's energy absorption capacity under dynamic loads and impacts has been significantly enhanced.The research has confirmed that by adjusting trace metal composition and optimizing heat treatment process parameters,the performance potential of 26CrMo48VNb pipe body can be fully tapped and its mechanical performance indicators can comprehensively exceed the standard requirements of V-class pipe body,providing a better material option for the petroleum industry.关键词
