Large-diameter HDPE plastic steel winding pipe
HDPE plastic-steel winding sewage pipe is made of rigid-plastic composite special-shaped strip through spiral winding welding (extrusion welding on the lap surface), and its inner wall is smooth and flat, and the specification is dn200-dn3000mm. This kind of pipe has the advantages of corrosion resistance, light weight, simple installation, large circulation, long life (50 years), etc. It can replace pipes made of high energy consumption materials (cement, cast iron, ceramics, etc.), and is an environmentally friendly green product
The composite of each layer is carried out in the molten state of the plastic; it is completely different from the secondary melting and molding of the wound tube (hollow wall tube), so the layers are completely bonded and the fastness is very high.
The surface of the steel strip is specially pretreated to enhance the corrosion resistance of the steel and the adhesion between the steel and the plastic, and improve the peeling strength. When the plastic raw material is fully melted, it is wound and formed, and the overall structure of the pipe is firm and reliable. The use of special materials and processes not only solves the problem of steel plate anti-corrosion, but also solves the adhesion between steel plate and PE material, so that the service life of the pipe is the same as that of pure plastic pipe, which is guaranteed to be more than 50 years. Electric heat fusion connection, heat shrinkable tape connection, internal and external extrusion welding or a combination of multiple connections can be used to ensure a firm connection. Reliable connection can make the pipeline reach zero leakage.
