Pipe Freezing

About Rapid-Freeze

Founded in 2004 Rapid-Freeze has, over the years, established an impressive reputation for the provision of on-site pipfreezing within a wide range of residential, industrial and commercial situations.

With focus on customer service, training and Health and Safety, Rapid-Freeze is commitmed to the delivery of efficient and cost effective solutions on projects of all sizes.

Our success originates from the very high levels of technical expertise and professionalism that we employ to great effect in every commission we undertake. No two projects are the same of course, which is why our skilled engineers have to be resourceful, often using their experience of wider pipefitting issues to find the best solution to the challenge at hand.

On-site workmanship is of the highest calibre, and our operational flexibility enables us to work within clients’ tight and often shifting schedules.

This approach has helped to ensure the continual growth of Rapid-Freeze into the premier freeze company in Sydney and beyond.

What is pipe freezing?

A simple, cost-effective method to perform pipeline maintenance or pipeline modifications without excess draining.

Using liquid nitrogen, Rapid-Freeze can isolate the problem area in the line by freezing the product inside the pipeline to form a solid freeze plug. 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!

How it works

An effective means of system isolation, freeze plugs are developed within the pipe system through the application of liquid nitrogen. The cryogenic process begins with heat being drawn from the product inside the pipe until it reaches a temperature below its freeze point. Once an established freeze plug is formed, the Rapid-Freeze technicians will monitor the flow of liquid nitrogen to maintain the proper sized plug based on known system parameters.

Upon completion of the client’s work, we refill the downstream piping, equalize pressure on both sides of the Pipe Freeze Plug, turn off the nitrogen and let everything thaw out.
