摘要

对高压锅炉管内表面类裂纹缺陷的特征、来源、性质和危害性

以及相关标准中的规定进行了分析

提出了一种金相观察+定向压扁的特殊间接试验方法对锅炉管内表面类裂纹缺陷进行间接检验评定

并对GB 5310—2008提出了增加压扁试验抽样比例、把扩口试验作为必检项目等建议。

Abstract

The features

sources

and properties of craching like defects on inner surface of high-pressure boiler tubes

as well as their harmfulness and stipulations in related standards have been analysed

a special indirect test method

i.e.metallographic observation + directed flat-pressing

being put forward

and recommendations for perfecting the standard GB 5310—2008

such as in creaing the sampling ratio for flat-pressing test

and taking the hole-expanding test as a necessary item

being suggested.
