GASOSTATIC EXTRUDER Russian patent published in 2010 - IPC B22F3/15 

FIELD: process engineering.

SUBSTANCE: invention relates industrial equipment intended for processing parts in gas atmosphere at simultaneous effects of high pressure (up to 500 MPa) and temperature. Gasostatic extruder comprises container with top and bottom plugs that form working chamber, load bearing base and gas system connected with working chamber. Said container represents a unit consisting of three thin-wall sleeves pre-assembled with interference fit to produce uniform distribution of compression strains therein in winding high-strength tape on sleeves unit outer surface to make a belt. Central sleeve outer surface has multi-start channels for cooling fluid. Note here that antirust coat is applied onto outer sleeve inner surface and central sleeve with cooling channels.

EFFECT: reliable design, higher safety, antirust protection, reduced weight of container and base.
