ABSTRACT:
A method to provide a high pressure press with a replaceable wear liner. The wear liner is first inserted into the cylindrical pressure chamber of the press and the pre-stressed by the application of an excess pressure above the yield point. The excess pressure is sufficient to increase the diameter of the wear liner and produce a residual radial compressive stress that holds the wear liner in place. When the wear liner is removed from the press it is dismantled. The advantage of the invention is that the replaceable wear liner, and a high pressure press comprising it, may be relatively inexpensive to produce and the replaceable wear liner may be quickly and simply replaced.
