A series of mechanical tests 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.

We have designed, developed and engineered high pressure, high-temperature autoclaves with highly 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.

Pressure vessels with mechanical testing mechanisms provide the ability to action testing on components in environments that replicate real-life service conditions; especially vital in sectors such as energy, aerospace and nuclear.

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 components 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.
