Filed:

May 2, 2003

Appl. No.:

10/429156

Inventors:

Gardner Baldwin - Houston TX, US
Victor DeLeon - Alvin TX, US
Larry Sweeney - Houston TX, US

International Classification:

F16L031/00

US Classification:

285/256000, 285/222100

Abstract:

Swage end-connector for high pressure reinforced flexible hose particularly suitable in the petrochemical and drilling industries for hoses. Two connectors are disclosed one for intermediate hose pressure burst ratings up to 12,500 psi and internal diameters up to 3 inches and higher hose pressure burst ratings up to 18,750 psi and internal diameters up to 4 inches. Both embodiment connectors will withstand the rated burst pressure of the hose to which they are connected and will withstand a pump-off force that exceeds the burst pressure of the hose. That is, the hose will fail before the connector pops off the hose.

Gardner T. Baldwin - Houston TX, US

Assignee:

George Myer Company, Inc. - Houston TX

International Classification:

F16L 11/24
F16L 11/04
B29C 63/14

US Classification:

156188, 138129, 138137, 138125

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.

Inventors:

Gardner T. Baldwin - Houston TX, US
Larry M. Sweeney - Houston TX, US

International Classification:

F16L 35/00

US Classification:

285399

Abstract:

An improved 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 improved 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 improved connectors will withstand the rated burst pressure of the hose without pumping off or leaking thus any hose that utilizes the improved device will fail before the connector pops off the hose. The improved connectors are designed to meet or exceed the new API temperature ranges and new API flexible specification levels which became effective in October 2006.

Inventors:

- Houston TX, US
Gardner T. Baldwin - Houston TX, US

International Classification:

F16L 13/11
F16L 11/08

Abstract:

One aspect of the disclosure is a method of attaching a hose coupling to a reinforced hose. In one embodiment, the method comprises: skiving the first end of the reinforced hose to expose at least one reinforcing layer of a plurality of reinforcing layers of the reinforced hose; positioning the skived first end of the reinforced hose in an inner cavity of the hose coupling; introducing a vacuum into the inner cavity through a vent port in the hose coupling; and introducing a bonding agent into the cavity through an injection port in the hose coupling, wherein the bonding agent is drawn by the vacuum into the plurality of reinforcing layers of the reinforced hose.

Inventors:

Gardner T. Baldwin - Houston TX, US

International Classification:

F16L 11/08
F16L 33/01
F16L 33/00

Abstract:

An improved end connector for a high-pressure reinforced hose that is subjected to high frequency of pressure cycles and that provides for a low compression deformation of the reinforced hose is discussed. This unique end connector has a stem and ferrule that includes a gripper or cable lock region near a coupler, or outboard end and a substantially smooth length on an outer diameter (OD) of the stem and ferrule that extends from about the gripper region to a hose receiving, or inboard, end.

International Classification:

F16L 33/207
B21J 5/02

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.

International Classification:

F16L 33/207

US Classification:

285256

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.
