ABSTRACT:
A replaceable inspection plug assembly and method for its use with pressure vessels. The plug assembly comprises a collar seal welded onto a pressure vessel outer wall, and a threaded plug removably threaded into the collar and the vessel wall. The plug has a shoulder portion which is seal welded to the collar. For removal of the plug, the seal weld is first machined away using a special cup-shaped rotary machining tool. The plug is then cooled and contracted relative to the collar, and is then unscrewed and removed. Following inspection of the vessel interior, the plug is replaced in the threaded hole and the plug shoulder portion is rewelded to the collar to provide a structurally-rigid and leak-tight joint without need for subsequent stress relieving the welded joint.
