Hydrostatic Pressure Testing

Hydrostatic or hydraulic pressure testing of pressure vessels, pipework, components and systems may be required following manufacture, to prove the design, material quality / strength and / or sealing arrangements, to ensure longevity and reliability of manufacture.

For pressure vessels in use, hydro testing may be needed:

At periodic intervals
Following a statutory inspection where significant corrosion is identified
Where you have concerns about performance of “older” equipment
Following an incident, damage or repair to the pressure vessel

After extended periods of service, pressure vessels may experience excessive corrosion of the parent material resulting in a loss of wall thickness which may reduce the vessel’s strength.

Ultrasonic thickness measurement tests can be used to measure wall thickness and identify whether the pressure vessel can still perform at its required safe operating pressure.

By performing hydrostatic testing, ISI’s test engineers can assess the vessels suitability for future service.

Hydraulic & Pneumatic Pressure Testing

Hydraulic testing and implosion testing, on-site or at ISI’s test house to a maximum pressure of 10,344 bar / 150,000 p.s.i. on an infinite range of pneumatic and hydraulic equipment:
