Hydrostatic Pressure Testing

To ensure the highest quality of safety standards are maintained, ISI has a wide range of Hydrostatic Testing equipment and experienced specialist engineers available.

Hydrostatic or Hydraulic Pressure Testing of pressure vessels, pipework, components, and systems may be required following manufacture. These could be necessary to prove the design, material quality, strength, and/or sealing arrangements – to ensure longevity and reliability of manufacture.

For pressure vessels in use, a Hydrostatic Pressure Test may be needed:

  • white tick icon At periodic intervals
  • white tick icon Following a statutory inspection where significant corrosion is identified
  • white tick icon Where you have concerns about performance of “older” equipment
  • white tick icon 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.

Potential Risks of Not Carrying Out A Hydrostatic Pressure Test

Risk of Explosion

Pressure vessels which are not tested can fail causing, damage, injury, and death.

Corrosion

Can lead to increased damage over time.

Leaks

Can be dangerous if not rectified by specialist engineers.

Damage To The System

System can become damaged over time without regular inspection and testing.

Reduced Efficiency

Without a Hydrostatic Test, the system is likely to become reduced in efficiency and performance.
