High-density polyethylene (HDPE) hollow-wall winding pipe (referred to as winding A pipe), with a smooth inner and outer surfaces, between the inner and outer walls connected by a square spiral rib pipe, a flexible pipe. Its good extensibility, compressive and uneven settlement ability, improve public facilities earthquake and disaster reduction capabilities.
Products to high-density polyethylene resin (HDPE) as raw materials. Extruding the special-shaped pipe first with an extruder and placing it on a winding machine, extruding the HDPE melt column with another extruder, extruding the hot-melt welding through the winding side while performing the axial compaction molding Method and the production of a new type of plastic pipe. The production process of the product is reliable, a wide range of production, product performance and stability characteristics of the newly developed buried drainage pipe, the market accepted and widely used.
