["Die amerikanAPI- undischen und GB-erischen Normen für Ventile器一致吗?如果阀门的设计依据的是API-erische标准,但阀门制造商使用GB-erische标准进行生产可以吗?API-erische标准与GB-erische标准之间会不会有冲突?

你得对比一下,要看需要哪些数据,很多国家标准的数据是参考德标和欧盟的标准。

设计和制造遵循同一标准,不存在设计依据一个标准而制造依据另一个标准。

肯定不一样,光法兰尺寸就不一样,更别提其它的了。选型的话,选型错了,得不偿失,选高了,浪费钱呀

连接尺寸不一样,主要要看实际压力,实际压力达到公斤的话阀门壁厚以公斤制造没问题,连接尺寸按照API的标准来就行

差别比较大,尤其是API有专门的内件标准,那些内件材料细化需要特别注意,常规还是以现有规格尺寸差异,毕竟单位不一样。哪怕是管件道理也差不多。只不过管件国内化工部的标准就是大杂烩,里面收录了欧标、美标、苏标转化成的国标等等

不是一个标准,一个是API标准,一个是国家标准。两个标准
