Publication number: 20230022376Abstract: The present invention discloses a boss configuration for a Type IV composite pressure vessel (“CPV”). In particular, the invention provides liner-to-boss interface that allows the polymeric liner to wrap around the internal collar of the boss that extends below the flange. Since the wrap-around section of the liner conforming to the internal collar portion of the boss is subjected to pressure from all sides, the liner stays adhered to the boss when the inside surface of the liner in a CPV is subjected to internal pressure from the contained fluid.Type: ApplicationFiled: July 23, 2021Publication date: January 26, 2023Applicant: STEELHEAD COMPOSITES, INC.Inventors: Michael Stewart, Kaushik Mallick, Jake Schrader, John Cronin, Andrew Coors

Patent number: 11448364Abstract: The present invention provides lightweight high-pressure accumulators that avoids diaphragm failure observed in conventional diaphragm accumulators. Lightweight high-pressure composite overwrapped accumulators of the invention are made from a plurality of hollow casings that are mated to form an accumulator housing. The accumulator housing is overwrapped with a composite material to provide additional mechanical strength and structural integrity. More significantly, the accumulators of the invention includes a plurality of annular grooves and a plurality of bulb on the flexible diaphragm such that the plurality of bulbs on the flexible diaphragm are placed in the plurality of annular grooves that are formed between the first and the second hollow casing. In this manner, diaphragm failure is significantly reduced or even completely eliminated during repeated high pressure charge/discharge cycle of the accumulator.Type: GrantFiled: April 30, 2020Date of Patent: September 20, 2022Assignee: STEELHEAD COMPOSITES, INC.Inventors: Kaushik Mallick, Michael W.

Patent number: 9897255Abstract: The present invention provides a metal-lined composite gas storage device comprising a phase-change material coated on the exterior surface of a metallic liner. The presence of the phase-change material on the exterior surface of the metal liner reduces the temperature change within the interior of the metal liner during a gas filling process compared to a similar vessel that does not have a phase-change material coating, thereby allowing a significantly greater amount of gas to be filled at a given pressure.Type: GrantFiled: October 16, 2014Date of Patent: February 20, 2018Assignee: Steelhead Composites, LLCInventors: Andrew Coors, Kaushik Mallick, John Cronin, Michael W.

Publication number: 20110180548Abstract: A pressure vessel may be formed from a thermally processed metal tube. The thermally processed metal tube may be seamless with a large length to diameter ratio. End portions of the thermally processed metal tube may be formed at a first temperature below the lower critical temperature by a load less than about the ultimate stress of the metal.
