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:
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, 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:
Method of blow moulding a container from a parison of a thermoplastic material comprising at least one opening, wherein the method comprises - placing the at least one opening of the parison on a blow pin - arranging a moulding cavity surrounding the parison, - simultaneously blowing pressurised gas from the blow pin into the parison and expanding the outer cross sectional diameter of the blow pin and a blow moulding pin for performing the method is disclosed.
