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 one ore more 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 line freezes are thawed and the pipeline is back in operation. Standard pipe freeze plugs range in size from 1/2" to 36" 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 3,000 psi line pressure. Independent laboratory tests have documented that no physical change in the structural matrix of the pipe occurs due to the controlled freezing process.
Pipe freezing can be performed on a variety of pipes, including:
Titanium
1/2" to 48" (13mm to 1,220mm) OD
CoCast & Ductile Ironated & Lined Pipe
Vertical, Horizontal, Inclined
