1.PVC double wall corrugated pipe is a kind of outer annular corrugated smooth wall structure of a new plastic pipe.Compared with metal, ceramic, concrete and other pipes, double wall corrugated pipe has many advantages such as lower weight, lower cost, erosion resistance, smooth inside-wall, high intensity, abrasion resistance, easy connection and so on.
2.Features : double wall corrugated pipe extrusion line is configured with high-efficiency single screw extruder, laminar flow distributor, dual passage spiral composite extrusion die, corrugated forming system, spray cooling water tank, cutting unit and stack unit.High performance single screw extruder with special screw and grooved feed barrel can ensure good extrusion in high efficiency.The extrusion die surface is nitrided and polished. A wall thickness-regulating device is equipped in die lip to be suitable for production of different raw materials and ring resistance material. Special structure die make the thickness of the inner and outer wall even, and stable molding.
