How is hydrostatic testing done?

Hydrostatic testing is performed by filling a component with water and pressurising it to test its integrity. Appropriate connections are required to connect the pressure inlet of the product to the on-site instrumentation comprising pumps, regulators, accumulators, valves and pipework. This system is then used to increase the water pressure until the desired specification is reached. Calibrated pressure transducers are used to monitor the internal pressure as it rises. The pressure is taken up and held. If the pressure drops, this indicates that there is a leakage.

If there is a requirement to monitor visible leakage, submerged gas testing can be used as an alternative to hydrostatic testing as leak paths are identified through the presence of bubbles. Submerged gas testing can also be performed at Tyne Pressure Testing.

Hyperbaric Chambers

Our facility offers nine hyperbaric testing chambers ranging in size and pressure capability including the world’s largest, commercially available hyperbaric chamber which can simulate water depths down to 4,500 metres.
