casing when maximum tension strength is required. It is especially suited for surface casing and production casing in high-pressure high-temperature wells. BENEFITS • • • • Excellent gas-tight sealing Extra-high strength Low hoop stress Easy to use and repair Metal to metal seal and reverse angle torque shoulder Extra strength coupling • A 50% taper metal-to-metal seal is energized by a reverse angle torque shoulder, and is self-energized by internal pressure. • The coupling size is calculated to provide in excess of 100% tensile efficiency on heavy-weight casing. • The rugged design of the pin nose makes this connection able to withstand the high combined loads that are encountered in deep, high-pressure wells. • The coupling design minimizes hoop stresses, and is ideal for use with controlled yield materials in high-pressure high-temperature wells where sour gas or other corrosive environments may be encountered. • VAM® HW ST is the solution for a connection to withstand pressures as high as the burst and the collapse ratings of the heavy wall casing. Streamlined internal profile Hook thread design • A coarse thread pitch with a 3° reverse load flank angle gives the connection superior tension strength and eliminates the risk of jump-out. • Precision machining in the threads contributes to reduce hoop stresses in the coupling. • A steep thread taper allows for easy stabbing and fast make-up. Making up heavy wall casing with VAM® HW ST is as easy as with standard wall casing, with virtually no danger of cross-threading. • The ID is recess-free, with 6° mating chamfers at the end of the long coupling shoulder. This smooth bore allows the safe running of tools and minimizes turbulence and energy loss when high-velocity gas flows are encountered. Options • VAM® HW ST SC70 and SC80 (special clearance): for extra clearance applications, as when annular space is a limiting factor.
