| Abstract: | When welding parts are alloy steels,rated pressure is equal to or greater than 3.8 Mpa,its pot cylinder,setting the case with tin-in of weld,should divide wall thickness of pipe connector into two kinds: greater than 6mm and less or equal to 6mm,for each pipe joints,as per 1/200 soldering a specimen,and metallographic specimen is made along centerline of the test specimen in incision.This article from past Supervision and Regulation of Steam Boiler Safety and Technique version revision situation and weldin... |
