The pipe-fixing freezing method uses bypass pipes to make it possible to work on a faulty area, while leaving the water supply system running. Whether it is semiconductor companies, modern buildings or hospitals, their main problem is to find a way to fix their waterpipes without shutting down their whole supply system. The consequence of shutting down the entire water distribution network to allow repairs and maintenance is the loss of money and time. Therefore, our efficient no-shutdown pipe-fixing freezing approach is designed to provide a fast and reliable solution to this problem. 

Pertaining to cost-effectiveness, conventional construction methods are labor-intensive and time-consuming. Even when the production line shuts down, the manufacturer must continue to pay the workers. When water supply resumes, large pipelines (≥500 mm) may cause possible damage to equipment. Pipe failures result in billions of liters lost from water networks each day, which wastes water, causes damage to infrastructure, and interrupts continuous service. Water losses and the associated financial losses represent a serious problem for water supply companies all over the world. Hot tapping does not induce the aforementioned problems and costs less. 

From the perspective of time efficiency, conventional construction methods create residual water that must be discharged. This lengthens construction time inasmuch as everything has to be confirmed. By contrast, hot tapping exempts factories from these concerns and requires less time to complete. For example, forming a 300-mm branch pipe from a 500-mm main pipe, conventional construction methods would take 4–7 working days, whereas hot tapping would require only 2–3 days, reducing construction time by at least 50%.

For safety purposes, conventional construction methods for pipe cutting involve risk factors such as water leakage. These can lead to relatively high production risk, particularly in cleanrooms in high-tech industries. On the contrary, hot tapping is safe and can completely circumvent the risk of water leakage during pipe cutting.  

The pipe-freezing method is not harmful to the environment since the liquid nitrogen concentration completely vaporizes into the ambient air at the exit area. For environmental protection, conventional construction operations require discharge of a large amount of water resources, whereas hot tapping does not. It reduces water pollution and loss.
