超大型设备现场组焊质量控制

摘要

以某乙烯装置中汽油分馏塔为例,对超大型设备现场组焊过程关键尺寸、焊接变形、现场环缝组焊等关键质量控制环节进行了介绍,对超大型设备现场组焊质量控制具有一定的借鉴意义.%Taking a gasoline fractionating tower of an ethylene plant as an example, the experience of quality control over super - sized equipment fit - up welding at jobsite was introduced in detail, such as key dimension, welding deformation and jobsite circumferential seams fit - up welding etc. It provides reference for quality control over super - sized equipment fit - up welding at jobsite.
