Gas leak detection in gas pipes in the heated environment

Gas leak detection is the elementary testing of gas pipe parts for existing leaks. A gas pipe is considered leak-proof when there are no gas leaks from the exposed parts. This means that exposed gas pipes in particular are checked for external leak tightness. Leaks are detected by testing a connection point; e.g. at fittings, flanges, screw fittings and gas control valves. It is also important to check ducts entering buildings and gas pipes concealed in cavities at the air outlets. The application can be operated in different ways. A procedure that is still used despite its inherent danger is using a lighter to check the gas pipes. The definitely more usual and safer option is to use foaming media (leak detection foam) which produces bubbles as soon as there is a leak. The most up-to-date way to detect gas leaks is to use an electronic gas detector otherwise known as a “sniffer”.
