Metal sleeve seal for threaded connections

摘要

A threaded tubular connection having a sleeve seal for maintaining pressure sealing capabilities within the connection when exposed to extreme pressure and/or temperature variations. The sleeve seal forms a third part of the pin and box connection and is positioned axially intermediate the ends of the threaded engagement of the connection. The sleeve seal is constructed of a corrosion resistant metal having a Modulus of Elasticity and thermal characteristics that work with the Modulus of Elasticity and the thermal characteristics of the pin and box material to minimize leakage following exposure to extremes of pressure differentials and temperature.
