Helium Testing in Large Welded Storage Tanks

Brown Tank was recently contracted by a customer to test a tank floor for leaks and guarantee it's service. While we normally utilize vaccum box testing after welding seams in the floor, Brown Tank used helium testing over 2 days to give the customer 100% satisfaction. Helium is the best choice of tracer gas to find leaks for a number of reasons. It is non-toxic, inert, non-condensable, non-flammable and not normally present in the atmosphere at more than trace amounts. (5 ppm). Due to its small atomic size, helium passes easily through leaks. The only molecule smaller than Helium is Hydrogen, which is not inert. It is also relatively inexpensive and is available in various size cylinders. Brown Tank has the industry experience to perform this level of service for our customers.

"Brown Tank gives us the highest quality tanks and service. We wouldn't call anyone else."
