Abstract:
A device in the form of a pressure vessel for storing or transporting a fuel at a pressure in excess of 30 bar, wherein the pressure vessel has a ratio of the structural weight of the pressure vessel when empty over the certificated maximum transported fuel weight being in the range of 0.7 to 3.4.
Abstract:
The present invention relates to a method of rotational moulding where a heating structure is incorporated into the mould. Further aspects of the invention relate to a mould for rotational moulding comprising a heating element. In an embodiment, the mould is a pressure vessel for transporting and storing compressed natural gas. The heating element may be incorporated into the pressure vessel, or may be placed in contact with the pressure vessel for the duration of the rotational moulding process.
Abstract:
The present invention comprises a method of forming a thin metal layer on a dicyclopentadiene polymer surface and to constructs comprising the metalized layer.
Abstract:
The present invention is directed to a pressure vessel comprising a conductive composite boss wherein the composite boss is isolated from contact with materials with different electrical potentials so as to substantially eliminate the possibility of galvanic corrosion.
Abstract:
An internally coated pipe (10) for CNG distribution or delivery is disclosed, wherein the pipe is made of a thermosetting plastic material (3), and the internal coating is made of a metallic material (5). The thermosetting material (3) provides the required strength for the pipe (10), for handling the pressures to which the pipe will be exposed, e.g. up to 100 bar, whereas the metallic layer (5) provides the required impermeability to the component parts of the CNG.
Abstract:
A pressure vessel (10) for naval transportation of CNG comprises a vessel body adapted to receive and contain CNG, and an external layer (202) of a cushioning and thermally insulating material for insulating thermally at least a portion of the CNG. The thermally insulating material (202) is distinct from the vessel body. For example, it is a foam material. A rigid or semi-rigid skin or skirt (204) of a structural material can also be provided in contact with at least a portion of the cushioning and thermally insulating material (202), on the outer side thereof, to enable the pressure vessel (10) to be supported in a desired position on ships (301 ) or the like.
Abstract:
The present invention relates to a pressure vessel for containing or transporting pressurized gas. More particularly it relates to such vessels for containing or transporting compressed natural gas. The present invention also relates to a method of storing or transporting gas onshore or offshore. Moreover, the present invention relates to a vehicle for transporting gas, in particular compressed natural gas.
Abstract:
A CNG transportation vehicle comprising at least one vertially oriented, generally cylindrical, pressure vessel (10) of the type for containing and transporting CNG, the vessel having a generally cylindrical body and two ends and an opening in the form of a manhole at the top end thereof.
Abstract:
A gas loading or offloading system comprising, respectively, at least one loading or offloading arm, the arm having a pipe therein, the arm or the pipe, or both, having a hybrid metal-composite structure including a composite structural over-wrap.
