Summary for koroseal lining heat limit Discussion
Koroseal lining heat limitation is the key issue in this thread: Ezekiel Lyles asked whether a carbon bed tank lined with 1/8" Koroseal could be steamed or filled with hot water to kill bacteria and organics without damaging the lining. He had been warned that heat might deform the lining and cause it to detach from the tank walls, and he specifically asked whether 160°F would still be too hot. The reply advised getting a data sheet from B.F. Goodrich because Koroseal is a proprietary product. The answerer said the common application limit is not to use Koroseal above about 140 to 150°F, and added that Goodrich likely would not guarantee performance above 140°F. The practical takeaway is that 160°F appears to be beyond the commonly recommended range, so the user should verify the exact temperature limit with the manufacturer before using hot water or steam.
Q. I have a carbon bed tank for my water process system. The tank has a Koroseal lining 1/8″ thick. My carbon bed is filled with bacteria and I want to steam or fill the tank with hot water for a period of time to kill the organics in the tank. I have been informed that I cannot steam or use hot water as this will deform the lining and allow it to detach from the tank walls. Will hot water actually do this? What if the water temperature is kept at 160 degrees is this still too hot?
thank you for your feedback and help!

A. Hi, Ezekial. You must get a data sheet from B.F. Goodrich as this is a proprietary product. Common application is to not use Koroseal for greater than 140 to 150 ° application, and I think you will find that Goodrich will not guarantee it above 140 °.
