摘　　要：针对高压锅炉主蒸汽管道支吊架下方母材存在裂纹的问题进行深入研究,找出裂纹产生的原因,并提出改变支吊架管部结构的处理工艺,实践证明,采用这种处理工艺,可以保证主蒸汽管道的安全运行。The cracks in base metal under supports and hanger of the main steam pipes of high - pressure boiler was studied. The reason of generating cracks was found, at the same time the treatment transfor- ming the root structures of supports and hanger was proposed. Practice shows that adopted treatment could ensure the safety of the main steam pipes running.
