有人分享过,看是不是需要

ASME B31.3  31.1l里面有叙述。。。
一般说 PIPE是圆的。
TUBE是任意形状的空心截面的。。
我们常常用的无缝管 是圆的tube

谢过2楼连接，再次学习了。

下载了，谢谢分享

ASME规范中TUBE与PIPE的区别是什么？在哪儿有解释？
在 ASME B31.1-2014  Power Piping有定义
Chapter I    Scope and Definitions
100 GENERAL
100.1 Scope
100.2 Definitions
------
pipe and tube: the fundamental difference between pipe and tube is the dimensional standard to which each is manufactured.
A pipe is a tube with a round cross section conforming to the dimensional requirements for nominal pipe size as tabulated in ASME B36.10M, Table 1, and ASME B36.19M, Table 1. For special pipe having a diameter not listed in these Tables, and also for round tube, the nominal diameter corresponds with the outside diameter.
A tube is a hollow product of round or any other cross section having a continuous periphery. Round tube size may be specified with respect to any two, but not all three, of the following: outside diameter, inside diameter, wall thickness; types K, L, and M copper tube may also be specified by nominal size and type only. Dimensions and permissible variations (tolerances) are specified in the appropriate ASTM or ASME standard specifications.

谢谢大家的解释。非常感谢。

我也第一次学习，以前老工程师的解释是大管叫pipe,小管叫tube，看来差之毫厘谬以千里。
