Abstract:
The invention relates to a high-pressure device (1) having a cylindrical high-pressure vessel (3) and prestressing means in order to exert an axial pressure on the vessel. The vessel (3) can have been formed from a number of layers of composite material, such as glass, carbon or aramide fibres which are oriented in the peripheral direction and are embedded in a matrix of epoxy resin or polyurethane. By applying the axial prestress to the pressure vessel (3), the tangential stress is distributed more uniformly over the wall thickness of the high-pressure vessel (3), the stress decreasing at the inside of the wall and increasing at the outside thereof. As a result, the innermost fibres of a high-pressure vessel (3) made of composite material are subjected to appreciably less stress, which has a beneficial effect on the life of the high-pressure vessel (3), and all fibres of the wall are utilised effectively. Preferably, the prestressing means comprise a pressure ring (14) which can be brought into engagement around the pressure-generating piston (9) with one end face of the high-pressure vessel (3).
Abstract:
Method for the safety and extension of the operating life of pressure equipment comprising an internal chamber suitable for containing a process fluid, surrounded by a pressure-resistant body (1) equipped with weep-holes (2), consisting of a material subject to corrosion by contact with said process fluid during operation, coated inside with an anticorrosive lining (4) made up of several elements welded to each other, wherein said lining weldings (3) are completely isolated from contact with the process fluid of the normal operating run, by a coating with adjoining strips (or plates) (10, 10', 10", 10'''), of the same material as said lining (4) or other corrosion-resistant material weldable thereto, which are subsequently seal-welded on the edges to said lining (4) and to each other, characterized in that the arrangement and welding of the edges of these strips (10, 10', 10", 10''') are such as to create a network of underlying interstices (or meati) (9, 11), communicating with each other and with at least one weep-hole (2).
Abstract:
A high-pressure and a method for high-pressure treatment of substances. The high-pressure press comprises a high-pressure cylinder consisting of a number of concentrically arranged cylinder elements (1, 2, 3). The cylinder elements (1, 2, 3) are radially prestressed to a predetermined prestress and surround a high-pressure chamber (6) for accommodating a pressurized medium. A thin safety liner (3), which is intended to be placed in the high-pressure cylinder until a fracture arises on the safety liner (3), is arranged in the interior of the high-pressure cylinder. Further, means (14, 15) are provided to conduct at least part of the pressurized medium from the high-pressure chamber (6) when a fracture arises on the safety liner (3). The means (14, 15) comprise at least one channel (14) running essentially along the outer envelope surface of the safety liner (3). The method comprises using the high-pressure press without liner replacement until a fracture has occurred on the thin safety liner.
Abstract:
A device for helical arrangement of the bodies of high-pressure vessels comprises a frame (4) mounted movably along the axis of the body (1) of a high-pressure vessel. The lower part of the frame (4) carries a pressing mechanism (50 mounted movably along the radius of the body (1) of the high-pressure vessel in the vertical direction. A mechanism (6) for tightening the arranged steel strip (13) is mounted before the pressing mechanism (5) following the feeding direction of the arranged steel strip from a roll (9) of the steel strip (13) to the body (1) of the high-pressure vessel. The pressing mechanism (5) is provided with a beam (23) fixed on the frame (4) and provided in its turn with forks and rollers (20) oriented in the direction to the body. All rollers (20) are mounted in their forks (21) at a distance from each other which is equal to 10 to 50 thicknesses of the arranged steel strip (13) and are placed on the generatrix of the body (1) of the vessel along the whole width of the arranged steel strip (13). The mechanism (6) for tightening the arranged steel strip consists of a group of rollers (16). The last two rollers (18, 19) following the feeding direction of the steel strip are provided correspondingly with convex and concave surfaces facing the surface of the steel strip (13). Radius of curvature of those surfaces is determined by the thickness and mechanical properties of the steel strip (13) and by the value of plastic deformation needed for compensation of the bend of the edges of the steel strip (13) upon its winding on the body (1) of the vessel after the pressing mechanism (5).
