核电站主回路大厚度不锈钢管道的焊接

WELDING OF BIG THICKNESS STAINLESS STEEL PIPING OF MAIN LOOPS IN NUCLEAR POWER STATION

简要介绍了核电站主回路大厚度不锈钢管道的焊接工艺 ,在核电站建设中 ,接触高温强腐蚀或化学强腐蚀介质的管道常用奥氏体不锈钢制造。核电站主回路中的介质含有高放射性物质 ,焊接质量的好坏将直接影响到机组的安全运行。

In this paper, the welding procedure of the big thickness stainless steel piping of main loops in nuclear power station assemblies was briefly introduced. In the building of nuclear power station, the piping of big thickness austenitic stainless steel was used to resist high temperature corrosion or severe chemical corrosion. Because the mediums in main loops had high radioactive elements, the welding quality of main loops would directly affect safe operation of assemblies.
