摘要:
为了研究钢管防腐涂覆和现场冷弯过程对X100管线钢管性能的影响,通过模拟涂覆和拉伸试验,分析了热时效对X100管线钢管拉伸性能的影响规律,并利用透射电镜(TEM)观察分析了X100管线钢管的微观组织结构。结果表明,热时效使X100管线钢管的屈服强度和抗拉强度均有不同程度的升高,纵向屈服强度比横向对热时效更敏感,这主要是由于管线钢生产和钢管的制造过程引起了材料纵、横向晶粒尺寸及位错结构发生差异造成的。
Abstract:
In order to study the influence of steel pipe anticorrosion coating and onsite cold bending process on X100 line pipe performance, the influence rule of thermal aging on X100 line pipe tensile property was analyzed by simulating coating and tensile test, and the microstructure of X100 line pipe was observed and analyzed by using transmission electron microscope(TEM). The results showed that the yield strength and tensile strength of X100 line pipe were enhanced in different degrees because of thermal aging; the longitudinal yield strength of X100 line pipe was more sensitive to thermal aging than transverse yield strength. This was mainly due to the differences of grain size and dislocation structure in longitudinal and transverse direction caused by the steel production and steel pipe manufacturing process.
