RHS profile for U-Stamp Vessel

[IdanPV]

Hello all,

I want to use RHS (Rectangular Hollow Section) as a pressure containing part in a U-stamp pressure vessel.
Am I allowed to do so?
Is there a material specification for this kind of raw material?

Thank you all

IdanPV, you might be able to use something like ASTM A-500 or A-513 under UG-10, if it is important enough to you.

I don't think any non-round tubing is listed in Sec II Part D.

Regards,

Mike

The problem with sloppy work is that the supply FAR EXCEEDS the demand
