When it comes to repairing your pipes in the winter with an epoxy pipe liner, you may be concerned about the freezing temperatures hindering the effectiveness of the liner while it is prepared and cures inside the pipe. Here at Nu Flow, we take cold weather epoxy pipe lining very seriously and implement cold weather protocols when installing liners and coatings in plumbing pipes that may be exposed to below freezing temperatures.

Common CIPP Cold Weather Installation Problems

Ideally, Epoxy pipe liners that are saturated with resin should be kept at a temperature at or above 70 degrees until installation for maximum results. In cold weather, maintaining the appropriate temperature through the preparation, insertion and curing phases can be problematic due to the temperature of the outside air and the temperature of the host plumbing pipe. If the temperatures are too cold, the epoxy and pipe liner could freeze, severely hindering the insertion and extending the curing time. When this happens, the pipe liner or coating may not adequately adhere to the host pipe, creating wrinkles and bulges.

Ways to Keep the Epoxy Pipe Lining Warm

In order to avoid the common problems with installing epoxy pipe liners and coatings in cold weather, several methods can be used to ensure the installation and curing of the liner are a success.

1. Practical Ways to Keep the Epoxy Warm

In order for the epoxy to thoroughly soak the liner, it must be mixed and held at the proper temperature. This can be accomplished by erecting a tent or temporary enclosed structure and heating the inside of with a space heater or salamander, providing proper precautions are taken when operating supplementary heating equipment. Once the desired temperature is reached, for both the interior area of the structure or tent and the epoxy has warmed, it can safely be mixed and the liner can be prepared for insertion. If a tent or temporary structure cannot be erected, the epoxy can be mixed in a heated outbuilding or the back of a utility truck or fully enclosed trailer that is heated or can be heated with supplemental heat cialis generico prezzo.

2. Heating the Host Pipe

In some instances, it may be necessary to increase the temperature of the host pipe in order to keep the epoxy saturated liner from cooling too quickly. This can be accomplished by blowing warm air into the pipe and erecting a temporary structure around the insertion point in order to keep cold air from coming into contact with the entrance of the pipe.

Epoxy Pipe Lining Curing in Cold Weather

When the temperatures are extremely cold, it can take longer for the liner to cure once it has been inserted and inflated inside the host pipe. In order to reduce the curing time, hot air, hot water or steam can be used to keep the temperature of the pipe constant. This will prevent the pipe liner and epoxy from freezing and reduce the curing time for cold weather installations.

Cold Weather Epoxy Pipe Lining with Nu Flow

Just because it’s cold outside doesn’t mean you need to hold off on your pipe repairs until spring. Here at Nu Flow, we can evaluate your plumbing pipes with a camera inspection to determine if they would benefit from the epoxy pipe lining process and install the liners in cold weather. This is because we have the tools, equipment and experience needed to safely and effectively perform CIPP in cold temperatures.
