Whenever pipe or sewage system work is on, one of the most difficult tasks to conclude is to stop the flow of liquid in the pipe. Earlier, it was an arduous task to conclude which used to take loads of time and money but with innovation in technology, it has become an easy deal now. Latest pipe freezing technology has brought in techniques that stops liquid flow in a pipe within seconds. The equipment used in Pipe freezing is known as
Pipe Freezer. It comes in a kit which is known as pipe freezing system kit.
Pipe freezing system uses dry CO2 ice to freeze contents in the pipe. Thus, the requirement to drain the system for any pipework has been faded away. Dry CO2 acts as a temporary ice plug which immediately stops the flow of liquid. This system works in almost every situation and offering greater benefit to users, it comes for much lesser price than you have assumed. Pipe freezers or freezing systems come is three sizes which allows them to freeze not only vertical or horizontal pipes but also pipes which are awkwardly placed.
Function of Pipe Freezers -
The main cooling agent or refrigerant used in pipe freezing system (PFS) is CO2. It lowers the surface temperature of pipe which freezes liquid in the pipe circumferentially. This icing process continues in inward motion unless the ice meets the center of pipe radius, which forms an 'ice plug.'
Now this ice plug keeps increasing along with the length of the pipe, making every content of the pipe solidified. With non-toxic and no-flammable nature, pipe freezing system or PFS is considered fully safe for pipework. Using this system you can freeze almost every metal whether it is copper, lead, alloy steel or iron pipe. And, most importantly, it is effective on plastic pipes too. Pipe freezers have the ability to solidify any liquid that converts in their solid version at a temperature of 25 degree celcius or below.
Pipe freezing system can be used diversified purpose, such as cooling systems, heating systems, fire protection systems, water treatment systems, chemical lines and many more. A normal pipe freezing kit includes Nylon zipper bag. This bag contains three different sized freezing jackets along with two high pressure hoses and one tee piece. Other ingredients of the kit are 5 wax fiber washers, safety glasses, hammer, gloves & illustrated instruction manual.
