The Tejas HiFLO™ Nipple is designed to be used with the Tejas HiFLO™ Lock in new well completions where an InjectGARD™ Safety Valve is used as either the primary safety device, zonal isolation tools, or as passive "surge-protection" during injection operations.  The HiFLO™ Nipple is available in CRA materials and has a reduced outside diameter (close to collar dimensions for 10,000 psi applications) for intelligent completions that could require significant control line bypass.  Available in a wide variety of premium threaded connections, the HiFLO™ Nipple can be used to provide continued injection safety in wells where the conventional Tubing Retrievable Safety Valves (TRSV's) have failed during the life operation.  A simple wireline run will bring the well back into regulatory compliance for continued operation with the combined InjectGARD™, HiFLO™ Lock, and HiFLO™ Nipple System.
