A leak test is performed to identify weak spots as well as to improve product design. The test is performed by using high pressure to check if there is a pressure drop caused by an unintended crack or hole.

Goals of the tests:

·         Improvement of seals

·         Identify the weak spot of a pressure component

·         Determine min and max burst pressure

·         Defining the product specifications

Leak tests are often performed before the distribution process in order to meet the safety and quality standards. Although most leak tests are destructive tests, there are also types of leak tests which are not leading to out of use parts:

·         Test on leaks of repaired parts

·         Check of leak tightness on connections

·         Check of seal alignment

The pressure drop can be recorded with our recorder systems or computer controlled systems and the test results are presented on certificates.

Another method of leak testing is pressurizing with gas. The gas leakage can be detected with a gas detection sensor or to look for bubbles by submerging the pressurized object in water.
