Although we ship tank liners all over the world, at this time of year, the majority of our liners go to areas that are experiencing colder climes. With that comes an increase in concern about cold cracking of a PVC liner. Fortunately it is a rare phenomenon and with some proper care can be avoided.

Grommets and a drawstring rope have always been the traditional method for fastening a tank liner to the tank. The drawstring rope is a fine method for small liners (under 3 ft. in any dimension) but the rope doesn’t securely fasten the drop in liner to the tank flange.

On occasion a tank containing a tank liner may be taken off line and stored for a period of time. Just as a tank liner can be stored on its own, if properly folded, there is no issue with storing a drop in liner in the tank itself.

With any type of lining system there is always the risk of damage to the liner due to objects falling in the tank. Even though drop in liners can be easily repaired it makes sense to try to avoid this issue in the first place.

Hard chrome plating solutions are notorious for breaking down tank liners at the area where solution and oxygen interact. This is because as the solution evaporates the fumes condensate back on the liner. That condensate is now at a concentration of chrome beyond which PVC can handle. This causes the liner to break down at this area while the rest of the liner that is under solution still has years of service life left.

One of the benefits of a drop in liner is that if it is damaged it can be easily repaired. However, that does require being able to locate the damaged area to know just where to repair the liner.
