Warm isostatic press production unit was designed and stamped according to Los Alamos National Laboratory's technical specification
Engineered Pressure Systems (Epsi) has recently completed a large order for a warm isostatic press production unit (WIP) for Los Alamos National Laboratory that will be installed at its facility in Los Alamos, New Mexico.
The ASME Div III coded vessel was designed and stamped according to Los Alamos National Laboratory's technical specification to have a 76cm inside diameter, 63cm inside length and a design pressure of 227MPa and temperature rating of ambient to 93C.
Other features included a remote control operator station with indicators, threadless closures held in place with a restraining yoke, programmable pressure rate and programmable decompression rate.
To ensure the proposed system would perform to Los Alamos National Laboratory's specifications prior to shipment, the entire system was assembled at Epsi's facility and performance tests were successfully conducted.
Epsi's standard WIP is a press with a high pressure vessel and pressurised fluid heating to 250C.
Designed for high productivity and low maintenance, Epsi's WIP is said to be ideal for all applications requiring moderate temperature during the application of pressure and can be customised to suit application-specific needs.
The WIP is capable of operating at pressures up to about 700 MPa, with control of pressurisation and decompression which result in products of uniform density, reducing internal stresses, cracks, strains and laminations in the part being processed.
Epsi's WIP is available in a variety of sizes from pilot to large production units, and features top closure and load handling systems designed to meet the customer's production requirements.
The WIP is equipped with safety and alarm devices, adjustable pressure set-points, dwell time and fluid drain settings.
The WIP also features a hydraulically intensified high-pressure pump and a decompression circuit, allowing for low wear.
High product repeatability is obtained through the use of elastomer molds.
The WIP offers automated fast fill and drain circuit with a low-pressure transfer pump.
Configurations available on the WIP include a low-pressure decompression system, yoke frame or threaded closure system, and a vertical or gantry top closure system.
