Flexible Polyvinyl Chloride (PVC) Secondary Containment Liners are more commonly used in the liquid fertilizer industry to satisfy many state secondary containment requirements for aboveground storage tanks.  Most secondary containment methods serve as catch containers and only come in contact with the product when it leaks from the tank.  A flexible PVC internal tank liner works differently and has added benefits beyond simply satisfying containment requirements.

Tank Liners are Primary Containment

PVC tank liners are situated inside the aboveground storage tank as opposed to most other secondary containment methods that are outside of the tank.

Extra Benefits of PVC Liners

The two main benefits of using a PVC tank liner are potential longer tank life and lower cost for required containment.  The life span of a tank in part depends on how long the shell material and welds are effected over time by exposure to product stored, the weather, and water.  Using a PVC liner creates a barrier between the potentially corrosive liquid product and the tank shell and floor.  This decreased exposure to liquid and corrosive products can increase the life of a tank.
