Abstract
An armoured flexible pipe having one or more of the following components, a pressure resistant armouring, a traction resistant armouring and/or an internal carcase, in which pipe at least one of said components comprises one or more elongated elements such as a shaped piece, a cable, a wire or a strip. The element is formed of a composite material with aluminium alloy matrix comprising reinforcement elements such as particles and/or whiskers.
Claims31
A reinforced flexible pipe having at least one of a pressure resistant armouring, a traction resistant armouring or an internal carcase, wherein at least one of said components comprises at least one elongated element fashioned as one of a shaped piece, a cable, a wire or a strip, said at least one elongated element being formed of an aluminum alloy matrix composite material having reinforcement elements including at least one of particles or whiskers made of at least one of alumina or silicon carbide at a weight ratio of less than 40%, with the particles having a size in a range of between 4 to 400 microns and the whiskers having a diameter of 0.01 to 10 microns and a length of 10 to 600 microns, said elongated element having a tensile strength of at least 300 MPa and a Young's Modulus greater than 75,000 MPa.
