Leak detection is a  process that identifies any defects that causes leaks and  will adversely affect the integrity of a component or process system.

All leaks need to be identified and repaired prior to commissioning of a process system or prior to putting the system back into operation after a shutdown.

Leak testing is of process systems must be carried out for the following reasons prior to introducing Hydrocarbons.

• To ensure that the process system’s start up can be planned.
• To prevent costly lost production time due to unplanned shut downs.
• To ensure that all leaks are detected and repaired under controlled conditions.
• To ensure that the health of personnel is not adversely affected by the escape of hazardous or poisonous gasses
• To ensure the safe operation of the customers equipment
• To ensure that the environment is not contaminated or polluted

Leak Detection Methods

• Hydrotesting with water or process fluids
• Soapy bubble leak testing with Compressed air or Nitrogen
• Nitrogen-Helium leak detection- Test medium consisting of 99% Nitrogen and 1% Helium gas

Why Helium Leak Detection

• Proven to be the best method for detecting hazardous hydrocarbon leaks before start up and operation.
• Accurate method of locating the leaks and quantifying system leaks in standard cubic feet per year (SCFY)
• Helium leak detection process can identify leaks as low as 0.1 scf of gas per year.
• If 100% Helium is used as the test medium, leak rates of 0.001 scf per year can be detected.
• The acceptable leak rate for the system is determined by the end client.
