A construction method that allows for the replacement and expansion of piping branches and valves with minimal water drainage!
The "freezing method (for buildings)" is a technique that uses liquid air (nitrogen) to freeze the water inside pipes, allowing for branch pipe and valve replacement work, 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 the water supply to the entire building. 【Features】 ■ The frozen section can temporarily serve as a substitute for a valve, leaving nothing on the piping. ■ It reduces the time required for water outage work. *For more details, please refer to the PDF document or feel free to contact us.

The basic principle is to combine it with other construction methods! The effectiveness of the combined construction methods increases, leading to a reduction in construction time.
The "DOWS method" is a technique used to assist "freezing methods" and "DSP methods" by temporarily stopping the flow of water (temporary water stopping). This method is not used alone; it is fundamentally combined with other methods. By adopting the "DOWS method," it is possible to avoid complete water stoppage, enhance the effectiveness of the combined methods, and shorten construction time. 【Features】 ■ Freezing is possible without operating existing valves ■ No concerns about damage, leaks, or discolored water due to valve operation ■ When freezing methods are applied at both ends, the area of water stoppage can be minimized ■ Installed at the section of pipe removal, leaving no saddle after construction ■ If the valve does not work and does not freeze with the "freezing method," it is also possible to apply the "DOWS method" later *For more details, please refer to the PDF document or feel free to contact us.
When freezing methods cannot be used! Mechanically stop water at any location!
The "DCV method" is a construction technique that involves mechanically stopping water by installing a saddle at any location on existing piping, in order to minimize the range of muddy water and water outages. Since VP pipes and ACP pipes may be damaged by freezing methods, the "DCV method" is adopted as an alternative. This method can stop water flow, so if customers request to carry out work while in a leak state, we will accommodate this request using this method. 【Features】 - Compact and lightweight design reduces the burden on piping during work and after burial. - Combinations with methods such as "freezing method" and "DCV method" are possible according to the application. - If water stoppage is needed after construction, it can be re-stopped by excavating to the flange area. - This method does not accommodate hot water piping. *For more details, please refer to the PDF materials or feel free to contact us.
It is possible to carry out the "closure work on the T-shaped pipe for two receivers" without shutting off the main pipe!
The "DSP Method" is a technique used for branching pipes in T-shaped pipes, split T-shaped pipes, and welded piping, where it is difficult to apply freezing methods. When using freezing methods for branching sections, there are conditions and limitations, but with the "DSP Method," valve replacement and shut-off work can be done safely and without worry. 【Features】 ■ Allows construction related to branching sections of piping that are difficult with freezing methods. ■ Enables smooth construction related to branching sections from large-diameter pipes, which was previously challenging. *For more details, please refer to the PDF document or feel free to contact us.
