High-Pressure Processing (HPP) and Autofrettage Systems
Pilot units and ultra-high-pressure generation for process development and component manufacturing.
High-pressure processing (HPP) treats products with high hydrostatic pressure and is used at pilot scale to determine process parameters for pasteurization and sterilization. Autofrettage is a pre-stressing treatment that creates permanent residual stress in a cylinder or tube, raising its pressure capacity and fatigue life; it is used in the manufacture of high-pressure components.
Typical building blocks
- 1
Pressure generation
Pressure intensifiers and motor-driven pumps generate the required pressure.
- 2
Process vessel
The product or component is placed in a pressure vessel designed for the target pressure.
- 3
Measurement and control
Pressure transducers and gauges, with data acquisition, monitor and record each cycle.
- 4
Safety equipment
Safety heads, rupture discs and relief valves protect people and equipment.

Frequently asked questions
What is HPP used for?
HPP applies high hydrostatic pressure to products. At pilot scale it is used to determine process parameters for pasteurization and sterilization before production-scale equipment is selected.
Why is autofrettage performed?
Autofrettage creates permanent compressive residual stress in the bore of a cylinder or tube, increasing its pressure capacity and fatigue life.
What do you need to prepare a quotation?
Maximum pressure, vessel volume, medium, cycle time and your safety and documentation requirements. Exact specifications are confirmed from the manufacturer's documentation.
