Comrise's Solid Wall Winding Pipe Machine, the culmination of two decades of extrusion innovation, is designed to produce seamless, leak-proof HDPE/PP pipes with uniform wall structure. Unlike hollow-wall designs, this system produces solid-wall pipes through continuous spiral winding and welding, resulting in improved pressure resistance and hoop stiffness.

Frequently Asked Questions
What is the difference between solid-wall winding and extrusion?
Filament winding builds the pipe layer by layer by fusing spiral strips of material together, creating a seamless structure with isotropic strength. Extrusion can produce pipes in a single pass, but the diameter is limited .
Can the Solid Wall Winding Pipe Machine process recycled material?
Yes. Our optimized screw design can accommodate 40% post-industrial regrind without compromising pressure ratings or weld integrity.
