The "freezing method (for buildings)" is a technique that uses liquid air (nitrogen) to freeze the 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 the water supply to the entire building. 【Features】 ■ Minimal water drainage - Allows for replacement even with integrated valves - Reduces construction time ■ Foam extinguishing is also compatible with freezing! - Numerous construction achievements using foam extinguishing agents - Reduces both chemical and processing costs ■ Water pressure resistance up to 1.4 MPa Due to an increase in inquiries from across the country, we established a Kyushu sales office in the spring of 2022. <Main achievements in Kyushu (partial list)> - Hotel New Otani - Comfort Hotel - NHK Fukuoka Broadcasting Station - Asahi Beer Hakata Brewery - Lala Place Atago - Nippon Steel Oita Steelworks, among many others Of course, we can respond anywhere in the country. *For more details, please refer to the PDF materials or feel free to contact us.

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. Recently, due to the revision of inspection standards for foam fire extinguishing systems, more companies are utilizing this method when replacing open valves. It can also reduce construction time and the cost of chemical disposal, so if you are interested, please feel free to consult with us. 【Features】 ■ Minimal water drainage - Possible to replace even with integrated valves - Reduced construction time ■ Foam extinguishing is also okay with freezing! - Numerous construction achievements using foam extinguishing agents - Reduced chemical and disposal costs ■ Water pressure resistance up to 1.4 MPa *For more details, please refer to the PDF materials or feel free to contact us.

• Special Construction 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.

The "freezing method (for buildings)" is a technique that uses liquid air (nitrogen) to freeze the water inside pipes, allowing for branch pipe work, valve replacement, and 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. To ensure that you can use the "freezing method" with even greater peace of mind, we have introduced a new "guarantee system." There are no cumbersome procedures or additional costs; it will apply simply by placing your order as usual. *For more details, please refer to the PDF document or feel free to contact us.*

The "freezing method (for buildings)" involves using liquid air (nitrogen) to freeze the water inside pipes, allowing for the replacement or addition of pipe branches and valves 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. A paper on the continuous water freezing method has been published in Science Advances, a globally recognized scientific journal. (We received assistance from Professor Yoshiyasu Muto of Keio University, Faculty of Environmental Information.) ■ The frozen section can temporarily serve as a substitute for a valve, leaving nothing behind in the pipes. ■ It can shorten the time required for water outage work. *For more details, please contact us or download the PDF.

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.

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.

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.

The "freezing method (for buildings)" is a technique that uses liquid air (nitrogen) to freeze the water in pipes, allowing for branch work, valve replacement, and 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. In the April 2020 issue of the Daiyu Freeze Newsletter, we introduced our construction achievements at a certain beer factory in Kyoto and a long-established inn in Oita Prefecture.

As a professional in renewal construction, Daiyu Freeze continues to protect the city's lifelines by conducting buried water supply pipe work. Here, we introduce a case of the DSP method for sealing the base of a dual-receiving T-pipe. 【Construction Example】 ■ DSP method for sealing the base of a dual-receiving T-pipe 【Construction Explanation】 ■ The branch side of the dual-receiving T-pipe was no longer needed, so it was removed using the DSP method and sealed at the base. ■ Even if there is a curved pipe attached to the branch side of the dual-receiving T-pipe, the combination with the freezing method made it possible to implement the DSP method. *For more details, please refer to the PDF materials or feel free to contact us.
