Utilizing existing pipes as they are! Stainless Steel Dynamic Flexible Pipe Insertion Method
The "SDF Method" is a technique that utilizes existing pipelines that have become difficult to use due to aging, allowing them to be repurposed. By inserting stainless steel flexible pipes into the existing pipelines, it has become possible to reuse pipelines that were previously deemed unfeasible for renewal. Additionally, since the length of a single pipe can be freely determined, the number of joints is reduced, which improves the quality of the pipeline. 【Features】 ■ Can be drawn in without regard to the burial angle of the existing pipe ■ Excellent durability, corrosion resistance, and pressure resistance ■ High durability and corrosion resistance due to the use of stainless steel materials ■ Achieves high seismic resistance through a flexible tube structure ■ High pressure resistance achieved through blade protection *For more details, please refer to the PDF materials or feel free to contact us.
