["Preguntando sobre la clasificación de tuberías GC y SH"

Thread Content

["Antes usábamos solo la clasificación GC, ahora con la estándtica estándar de petróleo y química,,,1需要改成SH3511中的SHA、SHB这种。还有一个问题是SH3511中只找到了SHA和SHB的规定,针对的是有毒和可燃物质,那高压蒸汽这种怎么分级。谢谢各位!"

"La clasificación de tuberías se见《石油化工管道设计器材选用规范》SH/T 3517"

"Lo encontr,,谢谢。还想请教一个问题,GC分级的话是DN51以上才需要。石化有没有对管径前提的规定。"

"Verifica la fecha de tu licenciaia,如果是在219年6月之后到期重新换证的则应该按新许可的范围设计,如果是以前换的证还未到期,则继续有效。"

"Lo que dices es correct。GC es la clasificación de tuberías industriales de presilía,,蒸汽的话看压力、温度来分的。GC可以是GC1、GCII、GCIII;SHA、SHB用来检验安装和焊接接头的。比如十个焊口,5%就是检验5个就行。还有无损检测工艺的选择(超声波、射线等)。GC与SH没有对应的关系。国标大于行业标准;蒸汽的看GBB51517有"
