High Ring Stiffness: Made from high-modulus polypropylene with an elastic modulus of up to 1850 MPa. The combination of winding structure and inner wall ensures a scientifically rational design with excellent sealing and zero leakage. Hot-Winding Forming Process: Ensures high quality of melt seams. The socket and spigot are integrated with welded joints, using electric fusion welding to form a sealed plastic pipe system, preventing any harmful substances from contaminating the soil. We focus not only on cleanliness above ground but also on environmental protection underground.
