Abstract
In order to repair the flange screwed holes of pipe spreader of fluidized gas producer,proper welding procedure and operation method were confirmed,and there were not any slag or lack of fusion in those repaired seams.After ISR with welding stress released,because of a number of screwed holes and welding stress,the inner diameter of pipe spreaders become smaller 0.5 ~0.6 mm than before,but the di-mension of redrilling screwed holes is agreement to design drawing.关键词
