Drop In Liners Need Protection in Cold Weather

Witt Liners ships tank liners all around the globe and often, they are heading into areas that are colder climes. Those climates bring about a different level of concern for drop in liners because they can crack easily when they are too cold. Luckily, we have found a way to ship them so that those risks are minimized.

Our flexible drop in liners are packaged in the best way possible so that we get the best shipping rate and so that they are safe from below freezing temps. When our drop in liners are in service, the colder temperatures are not a problem. But before they are placed in service, they can crack in cold temperatures during shipping.

Therefore, we have found ways that can prevent that, such as holding all shipments that will arrive in areas with temperatures below 32°F. We have found that by packing our drop in liners somewhat looser, the stress is reduced on the folded areas. We go one step further and place warning labels that the content will crack in cold. This serves as a reminder to the receiving party to allow the drop in liners time to warm up before unpacking.

It is our recommendation that when our drop in liners are received, the following precautions should be followed:

Do not remove drop in liners from their shipping container until they are at 70°F or above.

Install them in temps of 70°F or higher.

We have created this video that provides full instructions on installing you can view here.

Any drop in liners that has been subjected to cold cracking are repairable with either a flexible PVC adhesive or with a hot air gun. Each liner we ship out will have pieces of scrap material to be used for repairs.
