How to Protect Exposed Pipes From Freezing

The Dangers of Exposed Pipes in Winter

Exposed pipes can be the biggest headache for plant managers and maintenance personnel in the harsh winter months. Any sort of pump, valve, or process pipe that is exposed to the harsh effects of the Winter is susceptible to freezing and bursting. As you can imagine, this can create havoc in critical systems.

Glycol Tracing: An Effective Pipe Freeze Protection Solution

There are many ways to heat these pipes, but in extreme climates, one of the most effective methods is to apply glycol tracing. Since glycol does not freeze and doesn’t require any special handling in environments that need to be explosion-proof, it makes it an ideal solution.

Glycol has a very low freezing point which allows it to remain in the liquid phase, even in very cold temperatures. The exceptional thermal transfer characteristics also make it the obvious choice for a cost-effective heating medium.

Valve Solutions for Glycol Systems

ThermOmegaTech manufactures many valves that control the flow of, and maximize the effect of glycol

through these systems. Our most popular valves for use in glycol tracing include HAT and TV/HAT.

Automatic, Electricity-Free Temperature Regulation

Our valves are not reliant on electricity to operate. To regulate the flow of glycol, each of these valves contains a thermostatic element inside that modulates open or closed to maintain a constant discharge temperature.

Each of them improves system efficiency by automatically varying the rate at which glycol is pumped through the system.

Protect Your Employees From Freezing with Thermostatic Valves

Thermostatic Freeze Protection: Winter is the time to protect your pipes and personnel.

Water-bearing piping must be appropriately winterized to keep temperature-sensitive processes and equipment functioning optimally throughout the freeze season. When water lines to cooling and condensate systems, safety showers, and eyewash or facewash stations are left exposed to the elements, or their heat tracing fails, freezing temperatures can cause frozen or burst piping. This can lead to overheated equipment and severely dangerous working conditions for your employees, which can interrupt systems, burst piping, and cause lengthy and costly repairs.

If safety shower, eyewash, or facewash station water lines freeze, personnel could be at significant risk of being unable to cleanse after contamination exposure. Condensate drain lines are also in danger of freezing even if it is electrically heat traced and the tracing malfunctions or the facility loses power.

ThermOmegaTech’s self-actuating temperature control valves are the ideal water line freeze protection solution.

HAT/FP Freeze Protection Valve

The HAT/FP valve is designed to sense the water temperature in the pipe or ambient temperature, depending on installation. The valve will gradually open to bleed off the cold water when temperatures approach the valve’s set point, typically 35°F (1.6°C).

Once the flow is initiated, the valve will remain open until the discharge water temperature is 5 degrees above that, typically 40°F (4.4°C). Once the freeze danger passes, the valve will modulate closed again to conserve water and reduce wastewater disposal costs.

These 100% mechanical valves require no power source to operate, eliminating the human errors associated with manual valves. They can also save you thousands on your water or energy bills.

Result: Guaranteed freeze protection and water savings because of the reliable and automatic HAT/FP thermostatic valves.
