Welding on a Coded Vessel

Welding on a Coded Vessel

Welding on a Coded Vessel

(OP)
Gents,

in the national board code it says that when welding on a coded vessel which is "OF ROUTINE NATURE" is performed, the R-1 requirements are waived.  Does the repair of a seal welded tray on a contactor fit this?  We have a chimney tray with a possible bad seal weld, do we need an "R" stamped company to perform this repair?  

RE: Welding on a Coded Vessel

RNicastro-

This would have been better in the Boiler and Pressure Vessel engineering forum.

If I understand your situation correctly, you have a chimney tray which is seal welded to a tray support ring. The ring is not a pressure retaining component, though it does carry a load. In my opinion, the seal weld of the tray to the ring would not fall under the NBIC provided that there is some comfortable distance, say 1", from the seal weld to the shell. In that case, a "R" stamp holder would not be required to perform the repair.
