Summary of what we do.

We specialize in pressure vessel and pipe line testing. We conduct internal, external inspections and wall thickness tests. We ensure that the vessel has been prepared to our standards before pressurization takes place, water fill, pressurize, drain and vent the vessels. We see that the correct pressure gauge is fitted and that the R.V. is tested, fitted and sealed/locked. We confirm that a nameplate is fitted on the vessel and issue a detailed inspection report. In accordance with the Occupational Health and Safety Act or the Mines and Minerals Act.

Hydrostatic testing

Hydrostatic (Hydro) Testing is a process where components, such as piping or pressure
vessels are tested for strength and leaks by filling the equipment with liquid.

Hydrostatic testing works by completely filling the component with liquid (usually, but not always, water),
until a specific pressure is reached. The hydro test pressure often exceeds the designed working pressure
of the equipment, depending on the exact regulations and code requirements, as applicable. The pressure is
then held for a specific amount of time to inspect visually for leaks. The visual inspection can be enhanced
by applying either tracer or fluorescent dyes to the liquid, as required or needed. Strength is usually tested
by measuring permanent deformation of the container. Hydrostatic testing is the most common method employed
for testing pipes and pressure vessels.

Using this test helps maintain safety standards and durability of a vessel over time. Newly manufactured pieces are initially qualified using the hydrostatic test. They are then re-qualified at regular intervals using the proof pressure test which is also called the modified hydrostatic test.
