Pipeline Renewal Insertion Method "SDF Method"

Can be inserted without selecting the bending angle of existing pipes! Long pipes can be manufactured, reducing construction time!

The "SDF Method" is a new construction technique that allows for the insertion of stainless steel flexible pipes into existing aging pipes of small to medium diameter, including those with bends, which cannot be done with traditional insertion methods. Since it can be inserted regardless of the angle of the bends in the existing pipes, the need for construction of vertical piles is reduced compared to other methods. Additionally, because it allows for the production of long pipes, construction time can be shortened, and both the starting and reaching vertical piles can be made smaller compared to other methods, resulting in less area for road surface restoration, less construction-generated soil, and reduced generation of industrial waste. 【Features】 ■ Can be inserted regardless of the angle of bends in existing pipes ■ Shortened construction time due to the ability to produce 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 document or feel free to contact us.
