Spiral Wound PVC Tube

About this product

Spiral-wound liner repair involves assembling specialized, modular winding equipment underground; prefabricated PVC-U strip profiles and stainless steel strips are then fed into the machine.

The winding machine simultaneously winds these materials together, locking them in place via specially designed seam interlocking clips to ultimately form a continuous new pipe within the original host pipeline.

The primary raw material for the spiral-wound strip profiles is high-molecular-weight PVC, featuring a high-strength structural design characterized by a double-interlock T-rib configuration. This method is particularly well-suited for the rehabilitation of large-diameter pipes or box culverts.
