Pipe Freezing Services
A simple, cost-effective method to perform pipeline maintenance or pipeline modifications without draining. Using liquid nitrogen, IFT, can isolate the problem area in the line by freezing the product inside the pipeline to form solid freeze plugs. This allows for very little drain-down or refill, and in many cases, no system downtime. Once the work is complete the plugs are thawed and the line is back in operation. Standard freeze plugs range in size from 1/2" to 48" OD and can be performed on most fluids including petrochemicals.
Our repeat customers include power plants, hospitals, industrial companies, mechanical contractors, hotels and manufacturing facilities. With the use of liquid nitrogen, pipe freezing is accomplished by establishing a secure and solid ice plug to isolate pressures in excess of 3000 psi.
International Flow Service freeze plugs are constantly monitored and designed to withstand up to 8,000 psi line pressure or 225,000 pounds force. Independent laboratory tests have documented that no physical change in the structural matrix of the pipe occurs due to the controlled freezing process.
