PMM Metal to Metal Seal: High-Performance Heavy-Duty Threaded Connector
PMM Metal to Metal Seal is a heavy duty threaded connector for use in exploration and platform casing strings where high strength and pressure integrity are important. Compared to other connectors of similar performance, PMM Metal to Metal Seal requires low make-up torque and can be assembled using standard rig tongs. It has mechanical strength characteristics higher than those of the casing pipe. PMM Metal to Metal Seal combines a rugged, double-start thread form with a deep stabbing design to eliminate cross threading. The double-start thread reaches full pre loaded make-up in 1-1/2 rotations. Full make up is visually confirmed by inspecting external indicator faces. Sealing is provided by an integral metal-to-metal seal & with an elastomeric O-ring secondary seal.
PMM fast make-up high performance threaded, and weight set connector (sizes 18.625” – 40”). These connectors have passed the requirements set forth by ISO 13679:2019, CAL I, where internal analysis is verified and evaluated by physical testing through Internal & External sources.
