Hi,
Can anybody repair pressure vessel without having "R" Stamp? Data report is already submitted to National Board and vessel returned to Manufacturer for repair?
Pls. guide me.
Thanks
BPVN;
Some states in the US do not regulate pressure vessels. If the object is installed in a Jurisdiction that regulates boilers and pressure vessels you must have an R-Certificate from the National Board to weld repair the vessel. Mechanical repairs to a vessel can be performed, in some cases, without an R-Certificate. Contact your local Jurisdiction where the object is installed for the most complete and accurate information.
If a vacuum stiffener ring is interrupted by a nozzle on a cylindrical portion of vessel, how do we ensure that it has adequate moment of inertia to replace the cut ring? Is this allowed by code?
