Abstract:
The present invention concerns a light weight composite pressure container for fluids adapted to hold fluids under both high and low pressures, such as H 2 , industrial gases, CNG (compressed natural gas) and LPG (liquefied petroleum gas), as well as a method of manufacturing the same.
Abstract:
A boss (1) for a composite pressure container for fluids is disclosed. The structure of the boss comprises depressurisation means securing that internal pressure built up inside the boss is avoided.
Abstract:
A boss (1) for a composite pressure container for fluids is disclosed, in which the radial thickness of a lip (23) of the boss arranged between the coupling or valve member (5) and an imbedded member (2) is especially adapted to the intended pressure inside the container.
Abstract:
A boss (1) for a composite pressure container for fluids is disclosed. The structure of the boss secures that a user trying to open the container by removing a coupling or valve member (5) is warned of a remaining pressure before the coupling or valve member is fully released from the boss.
Abstract:
This invention concerns an inlet/outlet system for a composite pressure container for fluids. The inlet/outlet system comprises a boss with a valve member and/or means for reducing build-up of electrostatic charges, which system is designed to be used in a composite pressure container designed to hold fluids of both low and high pressures, such as LPG (liquefied petroleum gases), CNG (compressed natural gases), H2, and industrial gases.
Abstract:
The invention relates to a means for preventing build-up of electrostatic potential in a fluid container (10) during filling and/or discharging. The fluid container (10) comprises electrical insulating materials and a valve means (18) through which filling and/or discharging occurs. Means for reducing and/or eliminating electrical and/or electrostatic potential build-up during filling or discharging of the container (10) is arranged in conjunction with the container walls. Such means may for example be arranged in conjunction with the valve means (18), reducing and/or changing the flow velocity of the fluid and/or the flow direction of the fluid during the filling operation. The invention relates also to a method of avoiding build-up of electrical and/or electrostatic potential, the method comprising changing the direction of fluid flow at least once at the top end of the container, so that the flow of fluid into the container preferably becomes laminar and/or is depressurized and wherein the fluid flow velocity into the container (10) is reduced.
