The "SDF Method" is a new technique for renewing pipelines by inserting stainless steel flexible pipes into existing aged pipes of small to medium diameter, including those with bends, which cannot be constructed using conventional insertion methods. Since it can be inserted regardless of the bend angle of the existing pipe, fewer construction piles, such as vertical piles, are needed compared to other methods. Additionally, the ability to manufacture long pipes allows for reduced construction time, and both the starting and reaching piles can be made smaller than with other methods, resulting in less road surface restoration area, less construction-generated soil, and reduced generation of industrial waste. 【Features】 ■ Can be inserted regardless of the bend angle of the existing pipe ■ Shortened construction time due to the ability to manufacture long pipes ■ Reduction in road surface restoration area, construction-generated soil, and industrial waste ■ Excellent long-term corrosion resistance and durability ■ No occurrence of rust lumps or other issues due to corrosion, with no impact on water quality *For more details, please refer to the PDF materials or feel free to contact us.

• Renovation and repair methods

"Synapse Flex" is a piping component that allows you to freely bend pipes by hand to suit the conditions on site. There is no need to process straight pipes or combine curved pipes, which reduces the time and effort required for these tasks to almost zero. It makes it easy to bypass manholes and underground installations, align cores, and adjust angles, which have previously been challenging. Additionally, it allows for construction in narrow excavation widths, uneven surfaces, and steep slopes, significantly shortening construction time. [Features] - During installation, it can be bent by hand to bypass manholes and obstacles. - After installation, it acts as a flexible pipe that absorbs earthquakes and ground subsidence. - The ease of bending by hand reduces construction costs and time. - Fewer connection points reduce connection construction costs and leakage points. - Preventing leaks improves reliability of the pipeline and reduces maintenance costs. *For more details, please refer to the PDF document or feel free to contact us.

• Piping and electrical wiring materials

The "Synapse Joint" is a bellows-type expansion joint that has complete airtightness and does not require maintenance inspections. All materials that make up the pressure-resistant parts, including the movable components, are made of metal, eliminating concerns about material degradation during use and variations in strength that may occur during processing. Additionally, the movable part, the bellows, is covered with a steel outer tube, preventing the intrusion of soil and ensuring that it can withstand soil loads according to depth. 【Features】 ■ No concerns about material degradation during use or variations in strength during processing ■ Complete airtightness, no maintenance inspections required ■ Structure that prevents soil intrusion and can sufficiently withstand soil loads according to depth ■ High reliability against high pressure ■ Economical design suitable for usage conditions *For more details, please refer to the PDF document or feel free to contact us.
