Which standard should be followed for the overall geometric tolerances of pressure vessels?
Thread Content
Which tolerances should be applied to the overall shape and position of pressure vessels? Such as the total height, roundness, and straightness. Position tolerances such as the distance between the flange surface and the equipment surface, and the orientation of the pipe ends. It seems there’s no regulation mentioned within 150.
It can comply with Article 8.2 of NB/T47041-2014
You can also refer to HG 20584
It can comply with NB/T47041-2014.

All kinds of manufacturing standards are mentioned later, right?

It seems that there are strict requirements regarding the deviation in the total length of towers; I haven’t paid attention to other aspects yet. However, there are strict requirements for the length deviation between the connections of the local level gauges on vertical containers. I look forward to hearing from experienced users~
150 does not cite this standard; is it therefore mandatory, or is it merely for reference?
150 is not specified; there are requirements regarding the roundness of the cylinder and any misalignment. The total height was not seen.
