Leak Test

Leak testing is a method or process that identifies any defects that will adversely affect the performance or integrity of a component or process system.

With the full range of equipment fleet in country including N2 equipment, tanks, high pressure testing pump, instrumentation and testing accessories, TimEast will be able to support the various leak detection methods.

What is a N2 He leak testing?

Helium leak testing is used to find small leaks in larger volumes or larger leaks. Helium is used as a tracer gas and its concentration is measured.

Nitrogen leak testing is used to verify the integrity of the pipeline through which it flows.

Leak testing allows industrial facility operators to safely deliver their products while minimizing the risk of oil and gas or chemical spills through production channels.

Leak Test

Why do We Leak Test?

Health - To ensure that the health of personnel is not adversely affected by the escape of hazardous or poisonous gasses.

Safety - To ensure the safe operation of the customers equipment.

Environment - To ensure that the environment is not contaminated or polluted.

N2 He Leak Testing

Why use N2 and He for leak testing?

Nitrogen has many physical properties that make it uniquely suited for leak testing. It is an inert gas that is virtually unresponsive under normal industrial conditions. Gaseous nitrogen also prevents oxidation/corrosion reactions by eliminating water vapor and oxygen from sensitive equipment. These reasons make leak testing with nitrogen a superior choice over other methods, such as hydrostatic pressure testing.

Helium is one of the smallest gas molecules and is inert. Being inert, helium is relatively safe to use (as opposed to hydrogen) and does not react with any of the materials within the part to be tested. In most helium leak testing applications, mass spectrometers are used to detect helium. However, residual gas analyzers can also be used.
