Fresher Evolution HPP, LLC Engineers Have Designed a HPP Vessel That Greatly Increases the Current HPP Vessel Lifecycle

Fresher Evolution ASME engineers have designed Autofrettage vessels that will last hundreds of thousands of cycles, which is a significant improvement over the typical life time of current wire wound vessels in operation across the world.

Many companies have informed us vessels need replacing before the equipment is fully depreciated.

The HPP industry has been concerned with the life cycle of the current wire wound vessel technology. "Many companies have informed us vessels need replacing before the equipment is fully depreciated," says Eric Lockovitch - VP of Business Development.

Fresher Evolutions HPP's ASME certified P.E. engineers are utilizing Autofrettage manufacturing techniques to produce a vessel that is much stronger and more durable than current wire wound technologies. “The ASME U3 certified vessel has a three layer design and produces inward pressure of 300 MPa (43,511 psi) in a static state. That means the vessel will not stress outwards until the internal pressures exceeds 300 MPa, greatly reducing the Operating Pressure high stresses common with current designs,” stated Adrian Staruszkiewicz, ASME certified P.E. engineer.

Autofrettage is an elastic-plastic techniques to increase the pressure capacity of thick-walled vessels. When the vessel is subjected to an internal pressure, the internal portions of the part to yield and resulting in internal compressive residual stresses. The goal of Autofrettage is to increase the durability of the final product, while reducing the size and equipment cost. The technology is commonly used in the manufacture high-pressure pump cylinders, fuel injection systems for diesel engines, and battleship and tank cannon barrels.

Fresher Evolution is adapting this proven technology to improve a growing concern in the HPP equipment industry. As with all components in the Evolution Series the design improves current offerings while implementing proven technologies.
