工业锅炉胀管工艺浅探淮北电力技工学校（２３５０００）关敬东多年以来，我国锅炉行业对锅炉水管与筒体的连接均采用焊接或胀接。胀接形式较焊接形式的工作量和工艺难度要小得多。一般工业锅炉承压较低，对水质要求也不太高，若能确保管子与管孔壁之间的严密性，则胀接形...
Expansion of industrial boiler process exploration Huaibei Electric Power Technical School (235000) Guan Jingdong For many years, the boiler industry in China on the boiler pipe and the connection are welded or expanded. Expansion of the form of welding than the form of workload and process is much smaller degree of difficulty. General industrial boiler pressure is lower, the water quality requirements are not too high, if we can ensure the tightness between the pipe and the wall of the hole, the expansion joint ...
