We are an italian company, manufacturer of vertical SS316 tanks for food and beverage industry. We have a job where an american customer requires a tank with a heating jacket (made by pillow plate) and only the jacket must be U stamp. We have found an italian supplier that can sell to us a pillow plate already welded to a base plate that will be the ferrule of our tank. The idea is to receive the (flat) base plate with U stamped pillow plate already welded on, to roll bend the base plate and form tank ferrule, to close the ferrule by longitudinal welding, to weld nozzles to pillow plate jacket, to inflate the pillow plate, then to finish all tank.
The problem is we don't know if the welding of nozzles to pillow plate can 'break' the U stamping of the jacket.. it is enough to use an ASME IX PQR? must be this welding covered by U stamp? (we are not U stamp company).
Do you have any suggestion?
Thanks, Ually
