Tube包括Pipe。Pipe和Tube的定义如下:
- 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. Dimensions and permissible variations (tolerances) are specified in the appropriate ASTM or ASME standard specifications.
Tube主要用于换热,Pipe用于流体或介质的传输。
Tube的制造要求比Pipe高,因此相同材质和尺寸的Tube可以代Pipe,而Pipe通常不能代Tube。 |
