Inroduction of Pipe:

           HDPE Pipe that are produced by this line have excellent stiffness and  flexibility, heat resistance, aging resistance, high mechanical strength, resistance of environmental stress cracks, resistance to creep deformation, heat-linkage, and so on. So, it is a preferred gas and water pipe for ductwork system between city and its suburb, Large diameter HDPE pipes start to play very important role in the city water and gas supply systems.

Features of Line:

     HDPE Pipe Extrusion Line is a novel pipe extrusion line developed by FRIEND company through absorbing latest advanced technology. It is applicable for high speed extrusion of PE,PP,PB,PERT,ABS etc. This extrusion line is of beautiful appearance, high automation degree, stable and reliable manufacture. It is generally welcomed by vast consumers. This extrusion line is the finest choice for replacing imported extrusion line.

     High speed, high efficiency extrusion single screw extruder is specially designed for extruding PE etc. material, equipped with the lower noise, high speed and hard gear reducer. The Special grooved feeding bush with water cooling system results in increasing compression and filling factors. Specialised screw designs for high output, low melting temperature, good plasticization effection, lower energy consumption.

     Spiral diffluence type extrusion die is specially designed for PE extrusion. Unique design of low-pressure inclined flow passage spiral/lattice basket diehead, ensures low temperature and high plasticizing extrusion of PE pipes; Special designed die core spiral temperature control, ensures the performance of PE pipes; Multi-layer co-extrusion die offers the advantages of low cost and flexibility of layer structure with different material. it features in easy adjustment and even extrusion, ensures that melting pressure and flux are uniformity, the surface of pipe is smooth and shapely.

     Pipe marking line is extruded by smaller single screw extruder through the composited extrusion die.

Vacuum calibration water tank: it is equipped with two-stage vacuum system(for large diameter)advanced water recycle & high pressure cooling system, vacuum degree adjustment device and accurate water level & water temperature automatical control system. The accurate stannum bronze calibratation sleeve ensures fast cooling speed and molding of pipe. Its material is stainless steel.
