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.

IFT remains committed and proud to offer 2” - 36” cryostop pipe freeze plugs nationwide. IFT as offers industrial pipe freezeplug services and we have a few jobs where we narrowed down a leak on a 12-mile stretch of crude oil to 600' of pipe. 300 feet of pipe was exposed and the leak was promptly located and repaired. Pipe freeze plugging is a cost effective alternative to our mechanical linestop services and is designed to isolate sections of pipe where valves are in tight areas, unavailable or inoperable. Through a combination of IFT’s hottap / wettap, line stopping, and pipe leak detection freeze plug services, we can guarantee that your pipe systems will stay in service.

Pipe freeze plug technology is a simple, cost-effective method to perform pipeline maintenance or modifications without draining. Using liquid nitrogen or CO2 to isolate the problem area in the pipeline by freezing the product inside the pipe to form one or more solid ice pipe freeze plugs. This allows for very little drain-down or refill, having to bleed problematic air out of pipes during refills, and in many cases, no system downtime. Once the pipe work is complete, the freeze plugs are thawed and are back in operation. Standard pipe freeze plugs range in size from 1/2" to 36" outside diameter (OD) and can be performed on most fluids. Pipe freeze plugs are constantly monitored and are designed to withstand up to 3,000 PSI line pressure. Independent laboratory tests have documented that no physical change in the structural integrity of the pipe occurs due to the controlled freezing process using liquid nitrogen. Another benefit of pipe freeze plugs over the mechanical services method is that there are no bulky fittings left behind on the pipeline system and can be performed in tight locations.

Pipe freezing can be performed on a variety of pipes, including:

1/2" to 36" (13mm to 914.4mm) OD
CoCast & Ductile Ironated & Lined Pipe
Vertical, Horizontal, Inclined
Out of Round Carbon Steel

Cast Iron
Internally / Externally Coated
