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.
