Liquid nitrogen pipe freezing system is a technique which can be used to repair damaged pipes and maintain the flow of water through other systems. It is a highly effective method and is especially suited for large buildings. It involves pouring liquid nitrogen into a receptacle until the pipe's contents freeze solid. The freezing process can take anywhere from 3-5 minutes for a 25mm pipe filled with cold water.

The advantages of nitrogen pipe freezing are numerous. For one, it eliminates the need for a full shutdown of the system, which helps minimize the disruption of your service. It is also effective in hard-to-reach areas because liquid nitrogen freezes the fluid inside the pipe. Additionally, the process prevents the need for additional plumbing work, saving time and money.

The process is considered one of the best ways to prepare pipes for work. It eliminates the need to drain all fluid in the pipes, resulting in less time and money spent on refilling and cleaning. A liquid nitrogen pipe freezing solution is used to freeze the pipe's contents, which creates an ice plug which adheres to the walls of the pipe and prevents water from flowing.

The process is safe, fast, and completely effective. The first step is to wrap the pipe in copper tubing or an insulated jacket. Then, a patented control system measures the surface temperature and injects liquid nitrogen into the pipe through the wrap. The procedure is completely safe and can be done without shutting down the entire system.

The process also works for various types of pipes. For example, it can be used on large diameter pipes, such as sewers, and for pipes that are difficult to access. Besides, it does not require a lot of time and money, making it a convenient option for those with a busy schedule.

The process of pipe freezing can be temporary or permanent. It can be applied to pipes that are as small as 6mm in diameter and as large as 500mm. Larger pipes, such as air conditioning cooling towers, may need more clearance and access. Additionally, the pipe's proximity to freezing point can affect the quality of the freeze. It is also important to provide sufficient access for technicians to work on it.

One of the primary benefits of pipe freezing service is that it makes it possible to perform repairs without having to shut the entire system down. This is a critical factor when working with older buildings because shut off valves fail and vital plumbing work cannot be performed. Additionally, pipe freezing allows for repairs in difficult to reach areas. Using nitrogen pipe freezing, you can replace damaged pipes and modify your system without shutting it down completely.
