摘要： A conformable pressure vessel including pressure vessel segments defined by a cavity disposed within a liner. The pressure vessel segments receive and store a gas in a compressed state. Each of the pressure vessel segments includes a first section of the liner having a first diameter and a second section of the liner having a second diameter smaller than the first diameter. The conformable pressure vessel includes a reinforcement layer surrounding the liner, and an inlet in fluid communication with the cavity of the liner. The inlet receives the gas from a gas source. The conformable pressure vessel includes an outlet in fluid communication with the cavity of the liner. The outlet outputs the gas from the pressure vessel segments. The conformable pressure vessel includes a connecting tube in fluid communication with the inlet and the outlet. The connecting tube receives the gas from the outlet.

摘要： This invention relates to a pressure vessel comprising a hollow body comprising endless fibers embedded in a thermoplastic polymer, in which the thermoplastic polymer comprises one or more polyamides containing one or more aliphatic monomeric units, wherein the one or more polyamides have a CH2-ratio of at least 5.5 and less than 10, calculated by □ identifying the number of different aliphatic monomeric units in the one or more polyamides; □ determining the number of CH2 groups per aliphatic monomeric unit for each of these different aliphatic monomeric units; □ calculating the sum of the so determined numbers of CH2 groups; □ dividing said sum by the number of different aliphatic monomeric units in the one or more polyamides; taking into account only the aliphatic monomeric units present in the one or more polyamides in an amount of at least 10 wt % with respect to the total weight of the one or more polyamides.

摘要： A pressure vessel includes a vessel main body, a first protective member, and a second protective member. The vessel main body is configured to contain gas inside. The second protective member is configured to exhibit performance that is different from that of the first protective member. One of the first protective member and the second protective member has recesses that the other one of the first protective member and the second protective member does not have at an end on a peak of a domical panel side provided with the one of the first protective member and the second protective member.

摘要： This disclosure relates generally to a storage tank for storing a fluid, such as water, having a wall defined by a plurality of panels which are retained by opposed side edges between adjacent support members. The support members have a base portion and a support portion and are free-standing on the base portion on an earthen floor allowing the tank to be constructed at sites without concrete foundations such as a concrete pad or ring. The tank also has a liner that lines the interior surfaces of the wall and the floor. The main embodiment of the invention is based on a design where the storage water tank is divided by a rubber membrane from the middle of the tank. This will divide the single tank to act as two separate tanks with the ability to operate independently in terms of storage, water/liquid intake and water/liquid output through an outlet. The concept is to provide each half of the tank as a full tank from input and output separated by a rubber membrane.

摘要： A large volume natural gas storage tank comprises rigid tubular walls having closed tubular cross-sections that are interconnected at opposing ends with two other rigid tubular walls such that interiors of the rigid tubular walls define an interior fluid storage chamber. The storage tank also includes bulkheads positioned in the interior fluid storage chamber across intermediate segments of the rigid tubular walls and closure plates connected between exterior surfaces of successive interconnected rigid tubular walls to define sides of the storage tank. Interior surfaces of the closure plates and exterior surfaces of the rigid tubular walls define an auxiliary fluid storage chamber. The storage tank also includes exterior support structures extending through the closure plates and between the exterior surfaces of the rigid tubular walls on some of the sides of the storage tank to reinforce the storage tank against dynamic loading from fluid in the interior fluid storage chamber.

摘要： A high pressure tank includes: a liner having a space in which a gas is sealed; and a reinforcement layer configured to cover a periphery of the liner. The liner has a cylinder portion in a cylindrical shape, and a pair of dome portions provided at both ends of the cylinder portion in an axial direction of the cylinder portion. A curved surface shape of each dome portion is an equally stressed curved surface shape when an internal pressure of the liner reaches a setting pressure set higher than the atmospheric pressure.

摘要： A method for manufacturing a high-pressure tank including a liner and a reinforcing layer covering an outer surface of the liner includes: forming a cylinder member made of a fiber-reinforced resin; forming a pair of dome members made of the fiber-reinforced resin; and forming a reinforcing body that is the reinforcing layer by joining the cylinder member and the dome members. When forming the cylinder member, a resin-impregnated fiber sheet is wound around an outer peripheral surface of a mandrel to form a cylinder body, and a resin-impregnated fiber bundle is then wound so as to overlap the cylinder body.
