About International Flow Technologies (IFT)
Pipe freezing is a non-intrusive, cost-effective, and quick method to perform pipeline leak testing or maintenance modifications without draining the system. Using liquid nitrogen, International Flow isolates your problem area in the pipeline or vessel by freezing the product inside the pipeline to form a solid plug.
This allows for very little drain-down or refill and, in many cases, no system downtime.
Standard freeze plugs range in size from 1/2" to 36" OD and can be performed on most fluids including petrochemicals.
Once the work is complete, the plug or plugs are thawed and the line is restored to operation.
Freezes can be placed on pipes to isolate pressures in excess of 3000 psi.

Pipe Freeze Plug Videos:
Jeff Maichel of in Watford City, North Dakota completing a 16" freeze plug looking for freeze fractures within a 5 mile stretch of crude oil pipeline. IFT used its 400 gallon nitrogen freeze truck to access hard to reach areas on this job.
International Flow Technologies (IFT) Completed a freeze plug on a was in Wichita, Kansas on a project with SemCrude and with Gore Nitrogen working on a 12" steel pipeline freeze job and we are going to cut a section of pipe out to add caps to hydro-static test in each direction.
This job was 4- 8inch pipe freezes completed at the Washington D.C. at the Dulles International Airport. The pipeline modification was on the data cooling lines.
