Alteration of a top cover on an ASME VIII Div. I Pressure Vessel
Alteration of a top cover on an ASME VIII Div. I Pressure Vessel
(OP)
Hi there,
due to a defect we need to replace a bolted flat top cover on a U-stamped pressure vessel at our client's site. The vessel is located in Texas and has no NB registration (not required as per Texas jurisdiction).
Is it possible to replace the bolted cover with a new one (no standard blind flange) without the R-stamp? Are there any further regulations we have to follow for this alteration? Do we need to re-hydro test the whole pressure vessel again after mounting the new cover?
Any information on this topic would be very helpful!
Thank you very much in advance.
Have a nice day!

The vessel is still in service. The defect on the top cover is not safety relevant. We will get in touch with our client to clarify how we shall proceed with the alteration of the top cover.
Have a nice day!!
