Heat Recoverable Coupling Use in Naval Shipboard Piping Systems

Heat Recoverable Couplings (HRCs) represents a growing technology that employs the “shape memory” characteristic of Nickel-Titanium alloys to join pipe, as opposed to traditional welding and brazing methods. The development of material properties and HRC designs has resulted in a product that exhibits exceptional performance in a marine environment. The Navy has endorsed this new fabrication method and as additional fitting designs are developed, shipboard applications are increased. The Navy developed, and continues to maintain, an HRC training and qualification program for shipyard installers to ensure a quality process. In addition, the Navy is currently researching areas of support and onboard repairs to offer the fleet a total system package.
