A flexible pipe for conveying pressurized fluids that has an inner tubular layer, two reinforcing layers, an outer layer and a barrier layer. The reinforcing layers are comprised of metal cords wrapped around the inner tubular layer. The metal cords may be comprised of multiple individual wires twisted about themselves or a central guide line. The barrier layer may be positioned between the two reinforcing layers and penetrate therebetween. Additionally, a method for making a flexible pipe is provided, which includes the use of heat to facilitate the penetration of the barrier layer into each of the reinforcing layers.

A high temperature flexible pipe and method of making a high temperature flexible pipe is provided. The pipe can have an inner tubular layer formed of a high temperature thermoplastic, a first reinforcing layer, a second reinforcing layer and an outer sheath. In one aspect, an insulating layer may be provided between the second reinforcing layer and the outer sheath. A method of making a flexible pipe is also provided. The first reinforcing layer is wound around the inner tubular layer and the second reinforcing layer is wound around the first reinforcing layer. An outer sheaf can be formed over the second reinforcing layer. In another aspect, an insulating layer can be formed over the second reinforcing layer before an outer jacket is formed over the insulating layer.

The coupling includes a mandrel and a coupling outer sleeve. In a method for installing the coupling on a pipe, the mandrel is inserted into the inner diameter of an end of pipe with an outboard end of the mandrel protruding from an end of the pipe. Then the outer sleeve is positioned over the pipe to form a length of substantially concentrically arranged, overlapping parts of the mandrel, the pipe and the sleeve. Then the sleeve is crimped over at least a portion of length, which engages the pipe between the sleeve and the mandrel. Either before or after sleeve is crimped over the pipe, the sleeve is connected to the outboard end of the mandrel.
