Deepwater Connection

TenarisHydril Wedge 623 connection was developed to comply with recent changes in deepwater operating requirements in the Gulf of Mexico. The new connection has an additional external metal-to-metal seal that provides compression ratings of 80 to 86% efficiency in an integral connection. The new connection has sealing capabilities and compression ratings that make it suitable for severe deepwater and high-pressure applications. It has been tested under the International Organization for Standardization (ISO) 13679 CAL I-E testing protocol and meets additional operator requirements for survival loads in line with API RP96 criteria. The connection uses the company’s Dopeless technology, which enhances its performance and reliability and provides operational; well-productivity; and health, safety, and environmental benefits. The connection has a 100% external pressure seal. It has an outside-diameter (OD) clearance of 1.5 to 2% of specified nominal-pipe-body OD for high-clearance applications. The connection has exceptional torque capability and compression efficiency developed through the simultaneous engagement of opposing flanks of the dovetail thread. There are no drift restrictions after overtorque. The 100% internal-pressure-­rated metal seal maintains gas-sealing capability under high axial loads.
