Abstract: A high-pressure tank includes a reinforcing layer and a liner having a gas-barrier property and disposed on an inner surface of the reinforcing layer. The reinforcing layer includes a cylindrical reinforcing pipe having a plurality of cylindrical pipe forming portions coupled together, and a pair of semispherical reinforcing domes, one of the pair of semispherical reinforcing domes being disposed at a first end of the reinforcing pipe, and the other one of the pair of semispherical reinforcing domes being disposed at a second end of the reinforcing pipe.

Abstract: A method for manufacturing a high pressure tank capable of uniformly heating a thermosetting resin in a short time is provided. A method for manufacturing a high-pressure tank including: a step (a) of preparing a tank intermediate product including a fiber-reinforced resin layer formed by winding a carbon fiber impregnated with a thermosetting resin around a liner including a cap attached thereto; and a step (b) of performing a process for thermosetting the fiber-reinforced resin layer of the tank intermediate product by induction-heating the fiber-reinforced resin layer using induction-heating means, in which: the induction-heating means includes first induction-heating means for induction-heating a trunk part of the tank intermediate product and second induction-heating means for induction-heating a dome part of the tank intermediate product; and a temperature of the trunk part of the tank intermediate product and a temperature of the dome part thereof are controlled independently.

Abstract: There is provided a high-pressure tank manufacturing method that ensures a shorten heating period compared with a conventional one and eliminates a need for taking out a material for heating after heating. A high-pressure tank manufacturing method includes: disposing a conductive heating material on an outer periphery of a resin liner; winding a conductive fiber with which thermosetting resin is impregnated around the outer periphery of the resin liner on which the heating material is disposed; and heating the heating material and the fiber on the outer periphery of the resin liner by induction heating to harden the thermosetting resin.

Abstract: Provided is a tank inspection method capable of efficiently draining water injected into a tank at the time of inspection. A tank inspection method TIM includes a supporting step, a water injection step, a pressure increasing step, and a draining step. The supporting step supports a tank with the central axis crossed with the horizontal plane such that openings provided at both ends in a direction along the central axis of the tank become upper and lower openings. The water injection step injects water into the tank from the lower opening and discharges air inside the tank from the upper opening. The pressure increasing step increases water pressure inside the tank to a predetermined pressure by pumping water to the lower opening, with an upper valve, which opens and closes an upper flow path, closed, and the draining step drains water from the lower opening of the tank.

Abstract: A mandrel has an outer peripheral member that shapes an outer peripheral surface of a mandrel, and a regulation member that regulates movement of the outer peripheral surface toward the radially inner side. A manufacturing device for a tubular member includes a radial movement mechanism that deforms the outer peripheral surface by actuating the regulation member into the outer peripheral surface in a winding shape and the outer peripheral surface in a separable shape, the separable shape being obtained by moving the outer peripheral surface in the winding shape toward the radially inner side and allowing the mandrel and the tubular member to be separated in the axial direction of the mandrel.
