Piping construction "Freezing method (building)" continuous water freezing method 'DOWS method'

Piping construction "Freezing method (building)" continuous water freezing method 'DOWS method'

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.
