Abstract: A Specialized Fitting and a Method of Manufacture for swaging hose couplings to high pressure, high temperature reinforced rubber hose having a corrugated or smooth plastic/nylon/elastomer or metal lining (inner tube). The hose couplings include a stem having first hose grippers extending from and along a length of the outer surface; elastomeric sealing members located around and disposed along a length of the outer surface of the stem; and a ferrule attached to the stem adjacent ensuring a labyrinth seal between the inner tube and the hose coupling.

Abstract: A swage fitted end connector for high pressure large diameter reinforced flexible rubber hose utilizing sine-wave locking of the reinforcement and particularly suited to the petrochemical and drilling industries. Two embodiments of the connector for use with wire reinforced thin internal tube hose are disclosed: one with a diameter of 3-inches and for burst pressures up to 20, 000 psi and the other for a diameter of 5-inches and for burst pressures up to 18,000 psi. All of the connectors will withstand the rated burst pressure of the hose without pumping off or leaking thus any hose that utilizes the device will fail before the connector pops off the hose. The connectors are designed to meet or exceed the new API temperature ranges and new API flexible specification levels which became effective in October 2006.

Abstract: A Method of Manufacture for reinforcing the inner tube of reinforced high pressure flexible hose. The method essentially places carbon fibre filaments running axially (longitudinally) with the hose in the first several layers of the built-up inner tube. The filaments are placed as near as possible to the inner wall of the inner tube so that the fibres do not interfere with the overall bending radius of the reinforced high pressure flexible hose. The strengthened inner tube is far more capable of meeting the new API (October 2006) temperature and flexibility (pulsation) standards for oil field equipment reinforced rubber hose.
