摘要

对ASME及国内压力容器相关标准的新旧版本关于焊后局部热处理加热范围的规定进行了对比分析，指出某些标准对同类条款表达不准确，容易引起设计、制造和监检等各方争议。个别国内标准在新版中对加热宽度的规定欠妥。%The provisions for local postweld heat treatment heat range in ASME and old and new versions of domestic pressure vessel standards were analyzed and compared. It pointed out that the expression of similar provisions in some standards is not accurate, which could cause the controversy among design, fabrication, inspection and so on. Provision for heating width in individual new version of domestic standards is not appropriate.
