2). High Brunt Intensity and low weight
3). Good creep deformation resistance.
4). Outer pressure resistance.
5). Erosion resistance ( such as acid, alkali and salt etc. )
6). Production material low cost.
7). PLC computer control system with touch screen interface can realize automatic and reliable operation

Application of HDPE water/gas supply Pipe Extrusion Pipe:
It has been widely used for urban tap water network system; urban and rural drinking water piping system; Buried fire protection piping system; irrigation piping system for agriculture and forestry; civil building piping system; feed liquid conveyance piping system for chemcial insuatry, chemical fiber, food, printing and dyeing, pharmaceutical, light industry, papermaking, metallurgy and other industries. Its low cost of assembling, easy operation, easy connection and economical construction can make it wide foreground and market potential.

Features of Buried HDPE water/gas supply Pipe Extrusion machine:
1. Buried HDPE water/gas supply Pipe Extrusion machine designed with advanced technology includes one single screw extruder, extrusion die, vacuum calibration tank, water cooling tank, hual-off , cutter and stack unit. PLCcomputer control system.
According to customer demand we can supply two or three co-extruder.

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
