Atmospheric pressure tanks vented directly to the atmosphere are designed for pressure not greater or lower than the atmosphere. Our above ground tanks are pressure tested to 1psi of air pressure to check for leaks.

 

We can also make salt-water brine tanks for oilfield use:

400 & 500 BBL Flat & Sloped Bottom Gun Barrels.

Vic Fittings also available for these.

Underground Storage

 These are designed to be buried. They are thicker, with added ribs for strength. These tanks are vacuum tested to 6.5Hg and 9.1Hg to test for stress of earth and leaks. The amount of vacuum depends on what type of back fill you are using. What will be in the tank is very important. We will need to know if you are putting in water, potable water, or chemicals and the temperature of the materials you're putting in so we can match the appropriate resin.
