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 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 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 method discloses four embodiments for manufacturing a complete hose assembly from stock hose and discloses a technique for ensuring a labyrinth seal between the inner tube and the hose coupling. The method results in a hose assembly that will meet or exceed the requirements of the American Petroleum Institute for Choke and Kill Hose and/or Rotary Drilling hose.

Abstract

An improved swage fitted end connector for high pressure large diameter reinforced flexible rubber hose utilizing sine-wave locking of the reinforcement and carefully machined internal grippers to cause a portion of the reinforcement wire to connect directly to the connector and particularly suited to the petrochemical and drilling industries is disclosed. A connector for use with high temperature-high pressure large diameter wire reinforced rubber hose is discussed along with other embodiments. All connectors will withstand the rated burst pressure and temperature of the hose without pumping off or leaking; thus, any hose that utilizes the improved device will fail before the connector pops off of the hose. Two alternate embodiments are discussed.
