PURPOSE: Provided is a foam liquid for detection of gas leakage, which enables checker to easily and visually detect a gas leakage even though amount of leaked gas is small, and which enables checker to exactly and visually determine the location of gas leakage. CONSTITUTION: The foam liquid ...
In a method of detecting a leak in a hollow apparatus a continuous micro-crystalline film of a substance is provided on the surface of the leaking apparatus, gas is then introduced into the apparatus, and a soap or an anionic or nonionic surface active agent applied to the microcrystalline ...
(2) filling gas at a certain pressure inside the magnetic track brake electromagnet and keeping the pressure for a certain time; (3) coating liquid like liquid soap or cleanser essence which is easy to foam at welding seams of the magnetic track brake electromagnet, observing whether foam ...
in the case of generating a gas leak from whatever part of the container valve, this gas leak can be detected by the gas detection units 60, 80 in good sensitivity, as compared with in the case of applying soap and water solution by manual work, labor and time can be markedly reduced,...
