A composite pipe termination is provided. The composite pipe includes a composite pipe wall thickness and a cut end. An annular part of composite material is attached around the outside of the composite pipe at the cut end. The annular part has a radial thickness which tapers towards the composite pipe in the direction along the composite pipe away from the cut end to provide an exterior surface having a tapered portion. A pinning structure includes one or more pins which extend through the annular part and partially through the composite pipe wall thickness to further attach the annular part to the composite pipe.

A gland assembly includes a gland defining an annular ring, the annular ring defining a first gland end and a second gland end disposed opposite from the first gland end; and a gasket, the gasket defining a first gasket end and a second gasket end, the first gasket end disposed opposite from the second gasket end, a gasket bore extending through the gasket from the first gasket end to the second gasket end, a gland collar defined at the first gasket end, the gasket bore receiving the second gland end of the annular ring.

A pipe connection swivel joint assembly includes a pipe member having an end flange with a conical proximal surface. A split ring assembly includes a pair of swivel ring halves each having a conical inner surface disposed against the conical proximal surface of the pipe member. The pair of swivel ring halves further include a plurality of mounting holes extending axially through the pair of swivel ring halves and a plurality of ring fastening holes. An outer ring is connected to the pair of swivel ring halves by a plurality of split ring fasteners engaged with the plurality of ring fastening holes. The outer ring supports a pair of distance plates that are disposed between opposing ends of the pair of swivel ring halves.

A flexible pipe end portion connection structure is provided. The flexible pipe end portion connection structure includes a flexible pipe body and a joint. The joint includes a first end and a second end opposite to each other and has a channel extending through the joint in a direction from the first end to the second end. An inner sidewall of the first end of the joint has a plurality of first stepped structures, and an inner diameter of a portion of the channel corresponding to the first stepped structure gradually decreases in the direction from the first end to the second end. At least a part of an end of the flexible pipe body is inserted into the first end of the joint to fit with the first stepped structure.

A hose includes a tubular section having an outer tube and an inner tube. The inner tube forms a liner for the outer tube. Apart from being connected by connecting means near both ends of the tubular section, the inner tube is unconnected to said outer tube.

A tensioner may assist in coupling two pipe flanges. The tensioner may include a body and a piston. The body may include a central longitudinal axis, a pair of fastener holes extending through the body in a direction parallel to the central longitudinal axis, and a piston housing having an inner bore disposed about the central longitudinal axis. The piston housing may be provided between the pair of fastener holes. An axial end of the piston housing may define a distal end of the body. The piston may be at least partially disposed in the inner bore of the piston housing. The piston may be axially moveable parallel to the central longitudinal axis through an opening of the inner bore at the distal end of the body.
