PRESSURE TESTING

Pneumatic testing, also known as functionality testing, is used to ensure the product will work as it is intended to. It tests for external leaks and internal leak paths. 

External leaks are leaks on the outer body of a component. This type of leak would result in the substance in use  escaping the vessel and the pressure dropping resulting in the part not functioning correctly.

Internal leak paths are faults in a product that would allow high pressure chambers to leak in to low pressure chambers. The chambers will typically be manufactured to have pressure resistance relative to their use, therefore a high pressure leak into a low pressure chamber can be a big problem.

Both external and internal leaks have the potential to be highly dangerous if commissioned into use, especially when used in the gas industry, making pneumatic testing critical. 

CBE+ can conduct functionality testing from 0-150bar. 

Hydrostatic testing, also known as strength testing, is used to check the integrity/ strength of a product to ensure it is suitable to be used under different pressures. 

During this process the part being tested is either submerged in water or filled with water. The water is then pressurised, this allows for safe testing. 

Hydrostatic testing also checks the porosity of the component.
