High Pressure Mechanical Testing Systems

A series of mechanical tests under high pressures and variable temperatures are conducted to measure certain properties (elasticity, tensile strength, elongation, hardness, fracture toughness, impact resistance, stress rupture and fatigue); determining the characteristics and suitability of a material or component for a given application.

KW Designed Solutions has designed, developed and engineered high pressure, high temperature autoclaves with advanced mechanical testing devices incorporated into their design. These high pressure testing systems also allow for testing to be undertaken within an aggressive test media.

High pressure testing vessels with mechanical testing mechanisms provide the ability to perform action testing on components in environments that replicate real-life service conditions; especially vital in the energy, subsea, aerospace, defence and nuclear sectors.

This negates the need for separate mechanical testing machines to validate the performance of materials and joints in aggressive environments; measure the environmental effects on a component’s mechanical properties or determine flaw tolerance and provide accelerated ageing data.

Applications and Customer Uses

Our mechanical testing devices are incorporated into pressure vessels and autoclaves for customers, who provide testing services in materials research centres.

Testing is conducted to determine safe operating limits for materials, replicate extreme site conditions in laboratory conditions, perform accelerated age testing, validate materials and joining techniques to certify use in aggressive environments.
