pipe,tube,piping的区别? 根据asme b36.10 第一章的描述:the word pipe is used, as distinguished from tube, to apply to tubular products of dimensions commonly used for pipeline and piping systems. pipe nps 12 (dn 300) and smaller have outside diameters numerically larger than their corresponding sizes. in contrast, the outside diameters of tubes are numerically identical to the size number for all sizes. 翻译成中文就是:使用“管”(pipe)一词以区别于“管子”(tube),适于通常用于管道和管道系统尺寸的管状制品。规格小于等于12in的管(pipe)外径,在数值上大于相应的规格;相反,对于所有规格的管子(tube)外径,在数值上与其规格相同。 不知道这样说你是否明白?查看更多
