摘要:
对西气东输二线工程用X80级φ1 219 mm×18.4 mm螺旋埋弧焊管热影响区夏比冲击韧性和维氏硬度进行了统计分析。结果表明:X80螺旋埋弧焊管热影响区具有优良的力学性能,不同钢厂产品之间性能差异较小;热影响区夏比冲击功低于管体母材130J;硬度低于母材15~24 HV10,存在明显的热影响区“软化”现象。随着钢级的提高和焊接线能量的增加,热影响区的“软化”现象越来越明显,应当引起管厂和钢厂的足够重视。
Abstract:
The Charpy impact toughness and Vickers hardness of X80φ1 219 mm×18.4 mm SAWH pipe used in the Second West to East Gas Pipeline Project were analyzed,the result showed that the mechanical property of X 80 SAWH pipe HAZ is excellent,the property difference in steel pipes is less;the Charpy impact value of HAZ is 130J lower than that of base metal;the hardness value is 15~24 HV10 lower that of base metal,the “intenerating” phenomenon is obvious in HAZ.With steel grade improving and welding heat input increasing,the “intenerating” phenomenon is more and more obvious,the steel mills and pipe factories should pay more attention to them.
