Abstract: An end of a composite cylinder is formed about an end connection assembly having two longitudinally arranged pieces having a contour which prevents the withdrawal of the end connection assembly from the cylinder. The two pieces of the end connection assembly are relatively forced apart and a snap ring having a certain rest diameter is reduced in diameter and inserted into the end connection assembly to a position between the pieces. The snap ring then assumes its rest diameter positioned between the pieces, forcing them to maintain intimate contact with the inner surface of the cylinder, thus removing any residual gap from the assembly process and/or preloading the interface between the end of the composite cylinder and the end assembly prior to application of an axial load.

Abstract: An end of a composite cylinder is formed about a multipiece end assembly having a contour which prevents the withdrawal of the end assembly from the cylinder. The pieces of the end assembly are relatively forced apart and a spacer is positioned between the parts to maintain the pieces in intimate contact with the inner surface of the cylinder thus preloading the end prior to application of an axial load or removing any residual gap from the manufacturing process. The cylinder may have end assemblies at both ends and to which may be coupled external connectors such as flange members, for construction of a marine riser.

Abstract: A clamping device with an improved attachment of a component (3) inserted in a hole (2) has a casing (5) of a deformable material arranged in a recess (4) in the end of the component and a V-shaped notch open towards the end of the component, a wedge (10) inserted in the notch with its longitudinal direction parallel to the end surface of the component, a screw (12) engaging in a threaded hole (11) through the wedge and extending through a hole (13) through the casing, the wedge being pressed down into the notch of the casing by the screw thereby displacing parts of the casing located around the notch towards parts of the component located on both sides of the recess (4) so that the latter parts are pressed towards the wall of the hole at right angles to the longitudinal direction of the wedge.
