Abstract:
A plastic core container is reinforced with a fibre-plastic composite for storing pressurized liquid and/or gaseous media and includes one or more connecting parts located in the neck and/or base and/or cylindrical container part. At least one connecting part is configured to receive a screw-in cylindrical or conical pressure-line feed device. A cylindrical insert is mounted in a connection shank of the plastic core container and has an end collar that envelops or surrounds the end of the connection shank. At least two seals are positioned so that at least one seal lies between the insert and the inner surface of the plastic connecting shank and at least one additional seal lies between the insert and the pressure-line feed device to guarantee a tight and permanent impermeability in the vicinity of the connecting parts, even under extreme, fluctuating thermal and operational stresses.
Abstract:
The present invention relates to a pressure vessel for storage of solid, liquid and/or gaseous media under an operating pressure above atmospheric pressure, wherein the pressure vessel encloses a hollow space provided for storage of the medium, and is provided with at least one connector for loading and/or unloading. Because the pressure vessel is composed at least in part of a tube that in turn is manufactured from a fiber-reinforced thermoplastic, wherein the thermoplastic material contains more than 10% by volume of fibers with an average fiber length over 50 mm, the pressure vessel has a low weight and a very good resistance to corrosion and resistance to chemically aggressive media, yet it nevertheless withstands the mechanical stresses of the normal high operating pressures up to 25 Mpa.
