Can't it be rinsed off afterwards? Sounds like something the LDF suppliers come up with! How about the old cigarette lighter test?
Gas mains pressure and leaks
- Thread starter akist
- Start date
Guess it could be yes but wouldn't ever be sure to get it all off.
It's well known that some soaps contain salts/chlorine/ammonia that can certainly corrode copper/brass and s/steel. Nowt to do with the LDF suppliers.
Have you never heard of safety matches ?
In my work with chemical gasses, soapy water is a definite no-no!
Typical info from BOC here:
Leak Testing
Leaks may develop in any part of a gas system, particularly at joints

I always thought insulation tape was ok, as long as it's yellow?
My uncle worked for them , jeesh, it must be 20years ago now ... obviously it's always been the same approach for that stuff.
Why are we testing water pipes to 6 bar but gas pipes only to 30 millibar? Maybe 6 bar of water is similar to 30 millibar of gas in terms of ability to escape? I recently read that hydrogen escapes very easily for example.
As the smallest gas atom, it can find gaps that other atoms can't fit through!
Being so small, is one of the reasons why we use He for detecting leaks (down to 10¯6 mbar!) in UHV (ultra high vacuum) systems, it's also easy to detect, has a low concentration in normal air; and unlike H2, it doesn't explode!
