Liquid Nitrogen Pipe Freezing

Liquid nitrogen pipe freezing is a specialized service we offer to help commercial properties handle repairs without shutting down entire water systems. It is a fast, clean, and controlled method that keeps your building operating while we isolate a section of pipe for service. Many businesses cannot afford extended downtime, and pipe freezing gives us a safe alternative when traditional shutoffs are not practical.

What Liquid Nitrogen Pipe Freezing Is

Liquid nitrogen pipe freezing creates a temporary ice plug inside the pipe by applying liquid nitrogen to the exterior of the line. This freezes the water solid in a specific spot, forming a strong ice barrier that stops flow long enough for us to repair or replace valves, fittings, or sections of pipe. Once the work is complete, the ice plug melts and the system resumes normal operation.

When Pipe Freezing Is the Preferred Method

Commercial buildings often have complex plumbing systems with limited shutoff options. Pipe freezing is ideal in situations where shutting down the entire property would disrupt business operations, affect tenants, or create safety issues. We use it frequently in hospitals, offices, retail centers, multi unit buildings, and older structures with unreliable shutoff valves. It is also the preferred choice when the main shutoff is damaged or inaccessible.

Safety Considerations on Job Sites

Working with liquid nitrogen requires strict safety procedures. We ensure the area is well ventilated, use protective equipment, monitor pressure in the pipe, and follow controlled temperature application so the freeze plug forms correctly without stressing the pipe. Our team is trained to handle nitrogen safely, maintain a secure work zone, and protect both the plumbing system and the people in the building.

Limitations and Risks Building Managers Should Know

While pipe freezing is highly effective, it is not ideal for every situation. It works best on water filled pipes and specific pipe materials. Extremely old or compromised piping may not withstand the pressure changes during freezing. There are also size and temperature limitations that we review before recommending the service.

We evaluate the system carefully before starting so you know the method is safe and appropriate for your building. If pipe freezing is not the right approach, we provide alternative solutions that keep your operations running smoothly.
