Skilled pipe welders and brazers are in short supply. Expensive training efforts have failed to supply an adequate number of qualified personnel for shipbuilding programs. Field welded and/or brazed pipe and tubing pose numerous installation problems. The recent introduction of heat recoverable pipe couplings into shipyard production methods provides a means to help alleviate some of these problems. NITINOL, a "shape memory" alloy, was selected for evaluation of its applicability to shipboard piping systems. NITINOL couplings are cryogenically cooled, expanded, installed on a pipe joint and allowed to warm where they contract over the pipe forming a high-pressure sealed joint. The evaluation indicated potential labor savings warranting incorporation in ongoing contracts. Using Project Management, a major change in methodology was introduced into production late in two major shipbuilding contracts without the significant problems normally associated with a change.
