Pipe Freezing
Pipe freeze plugging is a simple, cost-effective method to perform pipe maintenance or line modification without shutting down your plant process. Using liquid nitrogen, Freeze Service, Inc., a division of T.D. Williamson, Inc., can isolate the problem area in the line with SOLID freeze plugs of the fluid within the line. This allows the job to be done with very little draindown or refill, no loss of expensive process fluids, and in many cases, no system downtime. Once the work is completed, the plugs are thawed and the line is back in operation. Standard freeze plugs range in size from 1/2" to 48" OD.
Successful pipe freezing is accomplished by establishing solid freeze plugs and maintaining them during the duration of the project. Freeze Service's freeze plugs are constantly monitored and designed to withstand up to 8,000 psig 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.
