Piping construction "Freeze construction method (building)" revolutionary thawing method for non-stop water freeze construction.

A groundbreaking non-flame thawing method has been developed that allows for plumbing branch and valve replacements and expansion work with minimal water drainage using a continuous water freezing method!

The "Non-Water Freezing Method" is a technique that uses liquid air (nitrogen) to freeze water inside pipes, allowing for the replacement of pipe branches and valves, as well as expansion work, with minimal water drainage. The frozen section acts as a stop valve, enabling plumbing work to be carried out without shutting off water supply to the entire building. After using the freezing method, it is essential to perform thawing work on the frozen areas, but a new thawing method called "DOWT" has been developed, which allows for thawing without the use of fire and in a short time! 【Features】 ■ The frozen section can temporarily serve as a substitute for a valve, leaving nothing remaining on the pipe. ■ Reduces the time required for water outage work. ■ Contributes to the longevity of pipes. ■ Can be thawed in the same time or less than using fire. * For more details, please refer to the PDF materials or feel free to contact us.
