HDPE Gas Supply Pipe Extruder Machine

HDPE Gas Supply Pipe Extruder Machine

Description of PE Gas/Water Supply Pipe Extrusion Line:

Diameter Scope: 20-1200mm 
We designs and develops  HDPE/MDPE gas and water supply pipe production line by ourselves.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 outdoor 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.  
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. The extruder is equipped with low noise fan, ceramic heating ring, high speed hard gear reducer; full-automatic vacuum loader. This configuration assures good plasticization and mixing effect. It also assures high speed, stable production and great output. 
Pipe Marking Line:  It is extruded by single screw extruder SJ30/25 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. In order to fit the performance of PE material and assure the stability of pipe diameter and roundness when producing thick-wall pipe with high speed, we adopt water film lubricating and water (or oil) circulation cooling.
