Self-contained high pressure autoclave test systems are perfect for short and long-term materials technology testing, along with smaller pieces of subsea components and products such as buoyancy macrospheres.

KW Designed Solutions design and manufactures self-contained high pressure autoclave testing systems, where all elements are integrated within a custom-designed skid, platform or benchtop rig. Several self-contained test systems can also be combined to create a multi-user test environment.

Our customised high pressure test systems are designed with easy access connection points for services such as electrics, pneumatic air and mains water supply. In some projects, the test media is stored within locally positioned holding tanks, to negate the need for mains water.

We combine all types of high pressure equipment into a multitude of configurations to create a bespoke, fully operational testing facility; providing customers with a complete turnkey solution.

Self-Contained High Pressure Testing Systems - Project Examples

Pressure Testing Subsea Buoyancy Products

KW Designed Solutions designed and engineered this self-contained pressure testing system for a global engineering group focussed on buoyancy materials testing for simulating variable ocean depths for rigorous product and technology testing.

The fully automated control system accurately controls pre-defined test procedures to simulate harsh environmental conditions, monitoring the programmed pressure and temperature cycles, time and date for full test reporting data.

Long-Term Corrosion Testing with H2S Media at High Pressure and Temperature – HPHT

KW Designed Solutions has designed, manufactured and installed a series of self-contained autoclaves for scientific and technological research laboratory facilities. This particular autoclave was for a world leader of corrosion testing services following international testing standards such as ASTM, NACE and API.

Medium Pressure, Medium Temperature Long-Term Corrosion Testing with Gas/ Seawater Test Media

One of the world’s leading global providers of materials testing technology and services approached KW Designed Solutions for the design, manufacture, installation and commissioning of a suite of self-contained high pressure, high temperature autoclaves.
