Abstract:This paper outlines the technical logic/steps that have been documented in JWES-CP-0902, “Guidelines for Repair Welding on Pressure Equipment”(hereinafter the Guidelines). The paper covers the work flow logic that can be followed by maintenance personnel as they address making a repair welding in pressure vessels/piping made of both ferrous and nonferrous materials after flaw detection during inspection during refinery operation. Material degradation factors that are considered include: strength loss, ductilit… Show more
