  • Liner for high pressure gas container and high pressure gas container
    Patent number: 7208207
    Abstract: A liner for a high pressure gas container includes a resin composition containing a polyphenylene sulfide resin and an olefin based resin. The resin composition has a methane gas permeability coefficient of 1.7×10?16 mol·m/m2·s·Pa or smaller at 40° C., and tensile elongation of 50% or greater after fracture at 23° C. A high pressure gas container having such a liner is also provided.
    Type: Grant
    Filed: January 31, 2002
    Date of Patent: April 24, 2007

  • Pressure container
    Patent number: 6227402
    Abstract: A pressure container in accordance with the invention is provided with a mouth piece having a cylindrical boss portion and a flange portion which is protruded from an outer periphery of the boss portion and a synthetic resin liner which is integrally formed in the flange portion. In the pressure container, an annular groove to which an inner peripheral portion of an inner edge portion of the liner is fitted so as to slide in a direction of expanding a diameter is provided on an inner side surface of the flange portion. Accordingly, it is possible to improve a reliability of an airtight seal in a bonding portion between a liner and a mouth piece.

  • Pressure vessel
    Patent number: 5758796
    Abstract: A pressure vessel includes a liner having an end wall assembly formed by connecting two rigid end wall members at a fixed distance from each other by a connecting member, and an elastic peripheral wall sheet fixed to the two end wall members so as to enclose a space between them. The two end wall members are made of aluminum alloy by an extrusion process. The connecting member is a pipe made of aluminum alloy by an extrusion process and having a large number of communicating holes in the pipe wall. The peripheral wall sheet is made of aluminum foil and is formed in a cylindrical shape so as to enclose the space between the two end wall members. Around the liner are provided a helical reinforcing layer and a hooped reinforcing layer which are both made of FRP. This pressure vessel is lightweight and can be easily produced at a low cost.
