Pressure Testing Methods & Testing Procedures

We provide pressure testing services ranging from hydrostatic pressure tests in the deepest oceans to air pressure testing to altitudes of 30,000 m (100,000 ft).

We operate hydrostatic pressure tests that can determine if your product will withstand the crushing pressures at the ocean depths in the marine industry, and vacuum chambers that will test its response to high altitude or sudden loss of pressure. Hydrostatic pressure testing is a process used for testing tanks and pipes for leaks. A hydrostatic test is performed by filling (pressurizing) the vessel or piping being examined and subsequently monitoring the level of pressurization for changes. If there is a lowering of pressure, there is a leak somewhere in the system.

The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test pressure. Pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss.

We can test for leaks using a variety of test methods and standards. When you are under pressure to get it tested, call us.

Pressure Testing Facts

The purpose of a pressure test is to ensure the safety, reliability, and the leak tightness of pressure systems.

A pressure test involves filling the vessel or pipe systems with a liquid which may be dyed to aid in visual leak detection and pressurizing the vessel to the specified test pressure.

Hydrostatic testing is the preferred method of pressure testing because it generates less stored energy, leaving a lower risk to workers.

Our Clients

We have performed testing for some of the major Tier I companies in North America and many of the premier companies in Atlantic Canada.

Your tests, results and all documentation are treated with the utmost discretion and security. No one but you will know what tests we performed or what the results were. We are ‘Canadian Controlled Goods Certified’, and take that certification very seriously. Please read our Privacy Policy for more information.
