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.
Spray cooling water tank: Long cooling unit ensures high efficiency
cooling, Unique pipeline design shorten cooling length, its
material is stainless steel.
Haul-off unit: special integral transmission unit avoids asynchrony
of individual transmission, Various control method ensures more
flexible & accurate orientation, Accurate pressure regulating
system makes hauling power adjustable. It has unique structure
& flexible operation, its speed can be adjusted by motor
inverter.
Cutting unit: Full-hydraulic design of cutting unit ensures
flexible pressure in state of cutting pipes, Flexible adjust for
saw position & cutting depth, Unique power input system ensures
high reliability of planetary unit, With ultra silent &
enforced sucking system, Unique non-scrap cutting unit enusre clean
cutting section for 16mm to 315mm pipe.
Control system: Adopts the one of the most advanced plastic
extrusion machinery control systems----PLC. It can ensure much
higher quality extrusion, PLC system ensures high speed and
convenient internet function that much more accurate and flexible
control, intelligentized control order make the operation more
simple.
