Ice Plug Freezing Services

International Flow has developed state of the art Pipeline Freezing services for your most challenging pipeline retrofit and repair.

Pipe freezing is a non-intrusive, cost-effective, and quick method to perform pipeline 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 ice plug. This allows for very little drain-down or refill and, in many cases, no system downtime. Once the work is complete, the ice plug or plugs are thawed and the pipeline is restored to operation. Standard pipeline freeze plugs range in size from 1/2" to 36" OD and can be performed on most fluids including petrochemicals.

Our repeat customers include United States Department of Energy, Oakridge Nuclear Laboratory, Kaiser Permanente, Cedar Sinai, AT&T data centers, Raytheon data centers, Pfizer data center, Bank Of America data centers, Goldman Sachs London, Boeing Corp, Northrup Grumman, The Division of Homeland Security, and many more power plants, hospitals, industrial companies, mechanical contractors, hotels and manufacturing facilities. With the use of liquid nitrogen, pipeline freezing is accomplished by establishing a secure and solid ice plug to isolate pressures in excess of 3000 psi.
