FIELD: oil and gas industry.SUBSTANCE: proposed is a gas tank sealing member and sealing gas tank structure that will improve the flexural strength at low temperatures in areas with a cold climate, maintaining a high gas barrier property. Cylindrically formed sealing element (5) of the gas tank, placed between the inner peripheral surface of container (1) forming a gas tank, and the outer edge of absorber (3) the oscillations which rises and falls in container (1) with movable piston (2) which rises and falls in container (1), on the outer peripheral side of movable piston (2), both surfaces of at least located at container end (7) from a container at container end (7) on the side attached to the inner circumferential surface of container (1) and situated in damper end (8) on the side attached to the outer edge of absorber (3) fluctuations coated EPDM, and the part that is not located at container end (7) and situated in damper end (8) is not covered with EPDM.EFFECT: use of the invention can improve the flexural strength of the sealing element and the gas tank reduces the heat leakage of the gas tank, and from him.8 cl, 10 dwg |
