摘要
文中对比了国内外常用阀门检验与压力试验标准,介绍了阀门压力试验程序及注意事项,以石油化工行业大批量阀门检验为案例,开展了全部外观检查和压力试验,并对检验发现的缺陷进行了统计分析,一定程度上反映了国产阀门产品质量,为阀门从业人员提供数据参考。
This paper compares the common valve inspection and pressure test standards at home and abroad,and introduces valve pressure test procedures and precautions.Taking a large scale of valve inspection in petrochemical industry as an example,the study carried out all appearance inspection and pressure test,and statistically analyzed the defects found in the inspection,which,to some extent,reflects the quality of domestic valves,and provides the data to valve practitioners for reference.
