We are using a 300lbrf slipon flg welded by an outside vendor. System is ~20psi-550 degF thermal fluid. The flg is extra heavy to allow torqing the bolts to get a good seal against the mating flg without bending the flgs. The flg is only welded to the pipe around the outside but looks like it should also be welded around the inside. Common sense would seem to ask for welding inside as well as outside. What codes would apply to this situation?
