Types of Pressure Testing Performed at GTS:

Hydrostatic Pressure Testing

Hydrostatic pressure testing refers to pressure of liquids in static conditions.

Proof of Pressure Testing

This is a non-destructive test used to verify that a component or system is capable of withstanding pressure above the design or operating pressure without sustaining damage or displaying leakage.

Leak Pressure Testing

Basically a form of “Proof” testing where the component is pressurized and if leakage occurs it can be located through various methods and the amount of leakage can be measured. Many items are engineered to allow for some leakage and quantifying that leakage is a vital aspect of product testing.

Burst Pressure Testing

This is the destructive version of pressure testing. Burst testing is used to establish the point where a component or system sustains permanent deformation or failure. It is also instrumental in defining if a component or system will fail due to mass leakage or catastrophic explosion. This is the “you make it; we break it “test.

External Pressure Testing

Some items require external pressure testing such as parts used under water. External pressure testing is more difficult on large parts due to the need for pressure vessel large enough to accommodate the part. We have external pressure capability depending on the size of the part and the required pressure range. We are always ready to add capability to meet your needs if the requirement exits.

Pressure Testing at Temperature Extremes

Certain product characteristics may require one or all of the above types of testing while the part is being subjected to steady state or cyclic temperature extremes. We have test chambers and thermal shock chambers allowing us to perform pressure tests over a wide range of temperature environments.

Vacuum Pressure Testing

Vacuum testing involves either subjecting a part to internal pressure or placing the entire part in an environment below atmospheric conditions.

Differential Pressure Testing

This is testing relating to the difference between the internal pressure of an item and the external atmosphere. It may also refer to the drop or difference in pressure experienced during flow of liquid or gas through an object.

Cyclic Pressure Testing

Internal or external pressure in or around a part is raised and lowered on a time basis or a high low pressure setting. This testing may also involve temperature extremes during the pressure changes.
