N-TWO Cryogenic - Pipe Freezing

Armed with more than 18 years of experience, N-TWO Cryogenic Enterprises Inc. confidently calls themselves the leaders in Ontario 's pipe freezing industry. Eliminate the inconvenience and cost of draining pipes by using this on-site service. Trained technicians visit your job-site to assess the work area, make recommendations, build a secure freeze plug and maintain it for the duration of the job, leaving you to do what you do best.

If you have to replace a valve, tie in a new line, repair a sprinkler system, pump, or damaged lines, trust the experts to avoid shutting down the system. Liquid nitrogen is fed into a containment unit placed around the pipe, which causes an ice plug to form, thereby holding back the fluid and avoiding the need to drain the system or store the liquid. Traditionally, pipe freezing was limited to carbon dioxide (CO 2 ) kits or refrigeration units. Carbon dioxide reaches a maximum cold temperature of -109°F (-78°C) whereas liquid nitrogen reaches upwards of -320°F (-195°C).

N-Two is able to freeze all metal pipes ranging from ½” to 48” and some plastics. They have the power to freeze most liquids including water, glycol, brine, organic solvents and some oils.

Just one of many examples includes a job done at Lester B. Pearson's terminal 3. Shutting down the cooling system to relocate a 6” line was not an option. Secure freeze plugs were formed in 2 separate areas of the line, which held 30% glycol. This allowed them to weld in four new joints. Moreover, it eliminated the need to displace thousands of gallons of glycol.

Don't drain the pipes - let N-Two freeze it!

Pipe freezing using liquid nitrogen is a simple and trustworthy process that saves time and money. It's as easy as 1, 2, 3.

1. When a Pipe is in need of repair,

2. Liquid Nitrogen is fed into a containment unit that isolates the area to be repaired.

3. A secure frozen plug is formed within the pipe and maintained until repairs are complete.
