Professional leak testing ensures the patency of aboveground tank systems. When there are no leaks and other disruptions, your organization is productive, your operation runs smoothly, and there are no environmental catastrophes to deal with.
There are a few more things you can do to ensure productivity and profits. One is choosing the right type of lining material during the storage tank fabrication. The other is the construction of secondary containment solutions.
Boosting fluid containment capability
The American Petroleum Institute established various standards for the installation and maintenance of aboveground storage tanks (ASTs). The guidelines include recommendations regarding interior coating or lining materials. Lining products continuously evolve in response to the changing qualities and properties of petrochemical and chemical products typically stored in huge ASTs in industrial complexes. The application methods and equipment requirements change with the times as well.
Secondary Containment Applications
Every single AST containing fuel is required by state and federal standards to feature a secondary containment application. The second container surrounds the first and is designed to contain the fluid contained in the event of a leak. The catch containers will only come in contact with the fluid once the protective structure of the trunk is breached.
One of the most popular products used for secondary containment is polyurethane. It is the preferred material for fuel because of its sealing characteristics, flexibility, and resistance to puncture. It is stable and strong and withstands possible degradation from ultraviolet radiation exposure. For containers used to store liquid fertilizer, the preferred containment liner is PVC or Flexible Polyvinyl Chloride. PVC meets the standards for containment as required by the American Petroleum Institute.
Liners helps increase the service life of ASTs. They are important for secondary containment. Some materials are affordable while others are more expensive. Make the best decision based on the unique needs of your setup.
