摘　　要：介绍支管座的发展历程、种类、用途和常用的3种支管座,对比新旧标准GB/T 19326—2022和GB/T 19326—2012中焊接的差异。重点介绍支管座焊接过程注意事项及支管座在核电、石化、天然气行业中的应用。实践证明,支管座与管道组对间隙和合适的焊接工艺参数是保证支管座打底焊的重要参数,内窥镜检查支管座根部的成形是支管座焊接质量控制检查的重要手段,焊后支管座焊缝无损检测是重要方法。To introduce development history,types,uses,and three commonly used types of branch outlets,and compare welding differences between new and old standards GB/T 19326—2022 and GB/T 19326—2012.Key points to introduce welding process precautions for branch outlets and their applications in nuclear power,petrochemical,and natural gas industries.Practice has proven that gap between branch outlet and pipeline assembly,as well as appropriate welding process parameters,are important parameters for ensuring bottom welding of branch outlet.Endoscopic inspection of formation at the root of branch outlet is an important means of quality control inspection for branch outlet welding,and non-destructive testing of weld seam of branch outlet after welding is an important method.
