Solid-Wall Pipe Skeleton Plastic Composite Pipe (SPCP-PE)
I.Pipe introduction
The solid-wall pipe skeleton plastic composite pipe is a new pipe with a kind of high-density polyethylene as its main raw material, and the pipe contains solid-wall internal pressure pipe of integral forming, reinforced layer and over-cladding layer from inside to outside. The said internal pressure pipe is a thin-walled pipe of integral forming, and it is of pure solid-wall extrusion forming. The wall of internal pressure pipe is uniformly cladded with a reinforced layer, and the outsides of internal pipe and reinforced layer are uniformly cladded with an over-cladding layer.
The reinforced layer of solid-wall pipe skeleton plastic composite pipe is wave-shaped steel strip with its inner and outer surfaces coated with a layer of special resin adhesive, or a hollow spiral pipe rib structure with its inner wall as single-wall polypropylene corrugated pipe; the reinforced layer and over-cladding layer ensure the external pressure bearing capacity of pipe. Under the condition of the same pipe diameter and weight, the external pressure bearing capacity of pipe is greatly enhanced and the pipe has a stronger serviceability and wider range of application; its maximum ring stiffness is SN16. The internal pressure pipe of composite pipe is of extrusion integral forming, so the whole pipe has no weld joints.
The solid-wall pipe skeleton plastic composite pipe is a kind of environment-friendly and secure product, and it is advantaged by light weight, high ring stiffness, strong full-flow resistance, high connection quality, long service life, corrosion resistance and convenient construction. It is widely used in urban drainage, long-distance water delivery and farmland irrigation, water conservation and so on. With the pipe diameter within the range of DN300-DN2400, light weight and good overall flexibility, it is the first choice of pipes for underground sewage and drainage and low-pressure water delivery.II.Pipe specification
