PE Pressure Pipe Production Line High Ring Stiffness Extrusion Line
PPR Pipe Production Line
HDPE pressure Pipe Extrusion Line is a pipe extrusion line
developed by HSD company through assimilate and master technology
introduced from abroad. It is applicable for extrusion of PE, PP,
PB, PERT, ABS etc. This PE pipe production line can instead
extrusion line imported from abroad.
This pipe extrusion line mainly includes single screw extruder,
molds, vacuum calibrating water tank, spray water cooling tank,
haul-off machine, cutting machine and bracket.
Plastic Pipes produced by this line have excellent stiffness,
flexibility, high mechanical strength, resistance of environmental
stress cracks, resistance to creep deformation, heat-linkage and so
on. It has become the first choice for the city gas pipe, water
supply pipe, foundation pipe, landfill collection pipe, watermain,
geothermal heating etc.
Application
HDPE pipe extruding line composed of single screw extruder and
corresponding auxiliaries, can produce all kinds of small diameter
HDPE plastic pipes continuously. It also can be used to produce PS,
PP, HDPE plastic pipes after replacing the screw. HDPE plastic pipe
is widely used for liquid conveying in agricultural, chemical
industry, construction industry, etc.
Structure
HDPE pipe extruding line is mainly composed of single screw
extruder, die-head, vacuum forming tank, spray cooling tank,
haul-off device, cutting device, and pneumatic discharging frame.
Single Screw Extruder
Single screw extruder is composed of AC motor, hard toothed surface
reduction gear, extruding system, heating and cooling system, and
electrical controlling part. AC motor transfer the power to
reduction gearbox via V-belt wheel and make screw rotate at certain
speed to adapt to extruding all kinds of plastics.
Die-Head
Die-head is mainly composed of mandril, neck mold, spiral body,
cover, die-head body, bolts, and heating rings. The inside surface
touching with plastic materials is polished and chrome plated to
ensure plastic materials flow smoothly and to ensure no rusting.
The uniformity of pipe wall thickness can be adjusted by bolts. The
copper calibrating sleeve fixed in die-head is mainly used to cool
down the fresh pipe and to calibrate the pipe outer diameter.
II. Machine Advantages
---High-efficiency extruder gives larger output, stable
performance.
For example
SJ90/33---600-700kg/h
SJ120/33---800-900kg/h
SJ150/33---1000-1200kg/h
---Compared with inflating method (internal pressure method)
1. For 24 hours working, it reduces 2-3 workers for each shift.
2. There is much waste pipe and material, no need workers to crush
waste material.
3. High-effeciency. Take Dimater 960mm as an example, Output is
approximately 60 pcs of 11.6meters pipe, it is much higher output
than that of inflating method.
4. Pipe wall is average and smooth, to reduce waste of raw
material, and pipe thickness is adjustable.
5. No need trim edge, once forming.
III. Main machine- High-effeciency single screw extruder
---Single screw is with barreir & mixing head; Barrel is new model
with slotting (channel), Both make security of good jellification,
large output and stable performance.
IV. Controlling system
The complete line could be controlled by PLC, with good
human-machine interface, all technical parameters could be set and
indicated by touching screen. Controlling system is designed
according to the customer; S requirement, to be with PLC, or
without.
Electrical system
---ABB frequency converter or EUROTHERM speed controller
---Japan RKC temperature controller
--- SIEMENS AC contactors
Service
Seller provide the technical service with free, and training the
workers of buyers.
Installation and testing
The seller can send 2 technicians to the buyer’s company for
installation and testing the lines. The round trip ticket,
accommodation, transportation, medicine treatment and insurance
caused by the seller’s expert in buyer’s country and 150 US dollars
per person per day will be covered by the buyer.
