Indoor Pipe Freezing Services
IFT’s indoor pipe freeze plug services enable critical pipeline systems to remain online and with NO costly shutdowns or system drainings!
For over 37+ years, IFT ranks nationally for our fast response time servicing indoor and outdoor critical pipe systems to prevent unwanted shutdowns. IFT remains committed and proud to offer 1/2”-36” Pipe Freeze Plugs Nationwide. Pipe Freezing 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 Hot Tap, Linestop, and Pipe Freezing 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 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. 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 line stopping method is that there are no bulky fittings left behind on the pipeline system and can be performed in tight locations.
Pipe Freeze Plug Limitations:
IFT can even perform pipe freeze plugs on flowing copper pipelines up to 2” with our innovative approach to problem-solving. Other pipe types with any flow cannot form freeze plugs using liquid nitrogen, therefore, we will use our mechanical Linestop service methods to isolate the pipeline system. Pipes that have a fast leak tend to have flow and in some cases cannot be frozen and will also require our Linstop services. Fluids containing glycol upwards to 20-30% and other petrochemicals with very low freeze points will also require our line stopping services.
