A method for molding a composite pressure vessel liner to secure a boss to the liner is described. The method comprises providing a moldable liner having an end section with a neck and a port. A boss is positioned around the neck of the liner and the liner is heated and pressure is applied to mold the liner to form to the shape of the boss. The angle of the molded liner secures the boss in place around the liner and it is able to withstand high pressures. A tool for molding the liner and a method for using the tool is also described. The tool comprises a tool body and a pipe having external threads. The tool body abuts the liner and the boss. Winding the pipe exerts pressure on the liner, which when heated, forces the liner to mold to the shape of the boss.

The invention herein relates to a flywheel capable of high speed rotational operation in excess of 15,000 rpm, the flywheel comprising a composite rotor having a polymeric matrix in which are embedded fibers helically wound at an initial angle with respect to the axis of rotation of the rotor of from about 50&#xb0; to about 80&#xb0; and increasing in a stepwise or continuous manner to about 90&#xb0;.

A method of incremental autofrettage is taught herein, whereby the cycle life of a metal liner in a pressure vessel is increased. This method serves to increase the yield strength of the metal liner through sequential work hardening due to repeated autofrettage at increasing pressures. By incrementally increasing the internal pressure used in the autofrettage process, the compressive stresses at an inner surface of the metal liner may be controlled so that post-pressurization buckling does not occur, yet the yield strength of the metal liner is substantially increased. The higher compressive stresses in the metal liner mean that higher Maximum Expected Operating Pressures (MEOPs) may be used without detracting from the cycle life of the metal liner, or alternatively, for lower pressures, a longer metal liner cycle life may be obtained. Either internal or external pressures may be used, generated by a pressure source, or a suitable die.

A transport tank for mounting to a truck has a composite tank body, an outer boss mounted to an outer side of the tank body, an inner boss mounted to an inner side f the tank body, and a flange disposed such that at least a portion of the inner boss is disposed between and abuts the inner side of the tank body and the flange. The tank body, the inner boss, the outer boss and the flange each have an aperture defined therein. The flange is fastened such that the outer boss, the tank body, and the inner boss are compressed by the flange.

Transport tank

The invention relates to improved metal/composite interfaces, particularly for risers used in offshore oil and gas production to connect a subsea oil well to a surface drilling/production facility. The invention provides a composite hoop structure configured to a bearing surface of a metal groove of metal liner over which axial fibers are laid. The composite hoop structure provides for improved transition of axial, torsional and compressive forces between composite fibers and metal surfaces of the metal liner.

Metal-to-composite interfaces

The present invention is directed to a protected pressure vessel comprising a one-piece electrically conductive composite boss that is isolated from contact with materials that have an electrical potential that differ from that of the conductive composite boss so as to substantially eliminate the possibility of galvanic corrosion cause by the differences in electrical potential.

A lined transport tank for mounting to a truck is provided. The tank has a lined tank body. The tank body has an inner surface. A baffle is removably connected to the inner surface of the tank body. A retaining system is removably connecting the baffle to the inner surface of the tank body. The retaining system has a pair of elongated members fixedly connected to the inner surface of the tank body. The pair of elongated members is restraining movement of the baffle in a first direction. A retainer is connected to the pair of elongated members. The retainer is restraining movement of the baffle in a second direction. The second direction is different from the first direction. A retaining system for removably connecting an element to a surface is also provided.
