HDPE Water_Gas Pipe Extrusion Line

Description

The Introduction of HDPE Water /Gas Pipe Extrusion Line:
designs and develops HDPE/MDPE gas and water supply pipe production line. This pipe production line has many features, such as: special structure, high degree automation, easy operation, continuous produce stable and reliably and so on. It is also applicable for high speed extrusion of PE,PP,PPR,PERT,ABS etc. The outstanding characteristics of this production line is that it can not only produce the pure PE pipe complying with the international standard, but also produce the wire reinforcing composite plastic pipe. 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 and outdoo r water pipe.
The whole production line, from charging to stacking shall be controlled automatically by PLC, having high reliability, easy operation and maintenance. With this extrusion line, a layer or multi-layer high strength wire such as steel wire, glass fibre and polyester fibre may be winded do existing pure PE pipe to increase the pipe working pressure to 4MPA.

Main Parameters of HDPE Water /Gas Pipe Extrusion Line:

The Feature of HDPE Water /Gas Pipe Extrusion Line:

HDPE/MDPE pipe extrusion line mainly includes single screw extruder, molds, vacuum calibrating water tank, spray water cooling tank, haul-off machine, cutting machine and overturning bracket.

Extruder: HDPE/MDPE pipe extrusion line adopts high speed and efficiency of single screw extruder.The screw has barrier unit, special material mixing components and new style of barrel grooves.
Color Line Extruder: It is extruded by single screw extruder SJ30 through the composited extrusion die.
Die Head: The material of the die head is high quality 40Cr. It is the most advanced spiral or lattice die head in the world, which assures stable extrusion in the production process.
Vacuum Calibrating Tank: The body is made of high hardness and good quality stainless steel board. It has advanced water circulation and high pressure cooling system, vacuum adjusting equipment and accurate water temperature and water level automatic controlling system.
Spray Cooling Tank: The body is made of stainless steel and the ductcoat is transparent soft PVC curtain. Stainless steel float adjusts water level and electricity controls water temperature.
Haul-off Machinery: We can offer two tracks, three tracks, four tracks, five tracks and six tracks Haul-offmachine according to different diameter and wall thickness of the pipe. It adopts frequency conversion. Every traction frame transfers with chain which ensures every track moving simultaneously.
Cutting Machinery: Automatic dustless cutting machine. Smooth cutting section, synchronous frequency conversion drive, high accuracy and low noise. Large diameter pipe uses full- automatic planetary cutting machine. It is synchronization with the whole production line.
Control System: We can offer SIEMENS PLC controlling system which is intelligent contr, , , olling system. Also we can offer ordinary controlling system which use SIEMENS electrical parts, Omron temperature controller. Intelligent control makes the operation simpler.

The Working Process of HDPE Water /Gas Pipe Extrusion Line:
Raw Material—Mixing—Auto feeder and drier—Single screw extruder—Co-extruder—Mould Calibrator—Vacuum forming table—Water cooling tank—Haul-off machine—Cutting machine— Stacker(winding machine).
