Introduction to the Freezing Method (Buried Related)

Introduction to the Freezing Method (Buried Related)

We respond to government offices nationwide! We will meet your needs with our unwavering and abundant track record and experience!

The "Freezing Method (Buried Related)" is a technique suitable for temporary water stoppage for replacement or rerouting of pipes. The frozen section can be temporarily used as a substitute for a valve, leaving nothing remaining in the piping. Additionally, it can shorten the time required for water outages. 【Features】 ■ Compatible with GX pipes ■ Supports DIP up to Φ500 ■ Enables reduction of water outage time and measures against red water *For more details, please download the PDF or feel free to contact us.

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

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

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.

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

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.

Introduction to "Frozen Method" for Plumbing Work in Firefighting Equipment Renewal!

Introduction to "Frozen Method" for Plumbing Work in Firefighting Equipment Renewal!

Firefighting equipment can be replaced with minimal water drainage! More people are utilizing the "freeze method" during the replacement of the deluge valves due to the revised inspection standards for foam firefighting equipment.

The "freezing method (for buildings)" is a technique that uses liquid air (nitrogen) to freeze the water in 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. 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.

New Ground Freezing Method "ICECRETE"

New Ground Freezing Method "ICECRETE"

Small amounts can extract a large amount of heat! A new ground freezing method that takes the Earth environment into consideration.

"ICECRETE" is a new ground freezing method that contributes to the mitigation of global warming by using natural refrigerants. By utilizing liquefied carbon dioxide (CO2) as a secondary refrigerant, the latent heat of vaporization of the liquefied carbon dioxide can be harnessed, allowing for cooling temperatures to be set as low as -45°C, compared to the -30°C limit of conventional brine. Additionally, it can shorten the overall construction period, including piping work. 【Features】 ■ Environmentally friendly ■ Capable of extracting a large amount of heat with a small quantity ■ Low power consumption ■ Realizes compact and lightweight piping ■ Possible reduction of construction period *For more details, please refer to the PDF document or feel free to contact us.
