Patent number: 8720066Abstract: The invention relates to a bellows hose, which is capable of being used without leakage, and which has a longer length and/or diameter than has been previously achievable. A bellows hose comprises an inner tubular bellows and an outer tubular bellows. An insulation layer is provided between the bellows. An armoured layer is provided around the outer bellows, to improve the insulation further. The hose can have length above 30 m and a diameter above 400 mm. A method of, and apparatus for, making the hose are also described, which involves the use of a non-metallic mandrel.Type: GrantFiled: October 22, 2012Date of Patent: May 13, 2014Assignee: BHP Billiton Petroleum Pty Ltd.Inventors: Joel Aron Witz, David Cox, Gerard Anthony Hall, Richard Smith

Patent number: 8713797Abstract: The invention relates to a composite hose, which is capable of being used without leakage, and which has a longer length and/or diameter than has been previously achievable. A composite hose comprises a tubular body of flexible material arranged between an inner and an outer helically wound wire. The hose further comprises an axial strengthening means adapted to reduce deformation of the tubular body when the tubular body is subjected to axial tension, the axial strengthening means being adapted to exert a radially inward force on at least part of the tubular body when axial strengthening means is subjected to axial tension. The hose can have length above 30 m and a diameter above 400 mm. A method of, and apparatus for, making the hose are also described, which involves the use of a non-metallic mandrel.Type: GrantFiled: October 22, 2012Date of Patent: May 6, 2014Assignee: BHP Billiton Petroleum Pty Ltd.Inventors: Joel Aron Witz, David Cox, Gerard Anthony Hall, Richard Smith

Patent number: 8079619Abstract: An end fitting (200) for terminating an end of a hose comprising a tubular body of flexible material arranged between inner and outer helical wires, characterized in that the end fitting comprises: an inner member (202) adapted to be disposed at least partially within the hose; and a hose engaging member (208) adapted to press against the inner member 202 to retain the hose between itself and the inner member (202). The end fitting also includes a separate means for retaining one or more layers of the hose, the retaining means comprising an outer retaining member (232) adapted to press against an inner retaining member (230) to retain the or each layer of the hose between the outer and inner retaining members (232, 230) of the retaining means.Type: GrantFiled: March 5, 2004Date of Patent: December 20, 2011Assignee: BHP Billiton Petroleum Pty LimitedInventors: Joel Aron Witz, David Charles Cox, Gerard Anthony Hall, Matthew Vernon Ridolfi, Anthony James Wort, Richard James Anthony Smith
