Finding leaks
Problem: You are pretty sure that a flange in gas service is leaking. How can you prove it?

Solution: Take a piece of 2-in.-wide masking tape and wrap it around the flange connection. Poke a pinhole in the center of the tape. If the flange is leaking, gas can only escape through that point.

Apply a soap and water solution to the pinhole. If bubbles or foam appear, the flange is leaking.
