摘要
对某石化公司60万t/a气体分馏装置丙烯塔现场组对环焊缝采用电加热法进行局部消应力热处理的方案和工艺进行了讨论,热处理效果良好,可为大型塔器现场组对焊缝的热处理技术提供借鉴。
For a petrochemical company's gas fractionation unit, production ability of 60 million tons one year, local electric post weld heat treatment (PWHT) for propylene tower girth weld was discussed, a reference for PWHT of large tower vessels at site was provided.
