Press Unit selected for Los Alamos National Lab

Engineered Pressure Systems advanced technology in an ASME Div III coded Warm Isostatic Press Production Unit (WIP) has been selected for Los Alamos National Laboratory

Engineered Pressure Systems (EPSI), a world leader in custom-engineered high-pressure solutions, has recently completed a large order of a Warm Isostatic Press Production Unit (WIP) for Los Alamos National Laboratory: it will be installed in their 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 30 inch inside diameter, 25 inch inside length and a design pressure of 33,000 psi and temperature rating of ambient to 200degF.

Other features included; remote control operator station with indicators, thread-less 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 specifications prior to shipment, the entire system was assembled at the EPSI facility, and performance tests were successfully conducted.

The standard EPSI WIP is a press, with a high pressure vessel, and pressurised fluid heating to 250C.

Designed for high productivity and low maintenance, the EPSI WIP is 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 100,000 psi (approximately 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.

The EPSI 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 moulds.

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.
