For more than 40 years EPSI has been recognized as the leader in high-pressure field. Our engineers hold patents based on innovation, state-of-the-art designs and actively contribute to various code and regulatory agencies throughout the world. We can design and build high-pressure equipment in accordance with ASME, TÜV and PED.

EPSI offers vessel designs to suit our customers requirements, threaded, yoke, wire-wound yokes, and pinned closure, and forged on wire-wound vessels.

Advanced thermal insulating systems ensure optimum thermal gradient and properly balanced heat up and cool down rates for economical use of power in hot isostatic systems and warm isostatic systems. EPSI offers fully automatic temperature and pressure controls provided with various degrees of sophistication from simple PLC controls to fully integrated PLC processes.

Prior to 1992 EPSI was well known in the high-pressure world under the name National Forge Europe in Belgium, and National Forge Pressure Systems Division in Massachusetts, USA. Both companies were subsidiaries of the National Forge Co., Irvine, Pennsylvania, producing precision- forged components. Since April 1996 EPSI is an independent company with headquarters in Belgium and Haverhill, MA. USA.

Due to extreme stresses and accumulated energy, often combined with high cycling rates, experienced engineering is particularly important in the manufacturing of high-pressure vessels. Metallurgical experience allows EPSI to select the best combination of strength, elasticity, ductility, toughness and fatigue resistance for the materials from which pressure vessels are manufactured. This experience has been built-up for over 40 years.

EPSI has built a tradition of excellence in high-pressure engineering and technology worldwide. More than 1,100 pressure vessels have been manufactured to date, using unique application specific approaches to R&D manufacturing and testing.

EPSI provides the highest possible quality assurance throughout the entire process of construction of high-pressure equipment. EPSI Belgium is TÜV ISO 9001 certified and EPSI USA is ASME U2 and U3 Certified.

For over 40 years, EPSI has provided comprehensive quality control of a broad range of products. Our extensive capabilities allow you to depend on EPSI as a sole source for high-pressure quality needs.
