Specification :

Pipe diameter: 16-1200mm besides we alo can supply double/ single wall corrugated pipe lines which can do pipe diameter: 4-1000mm.
Our company designs and develops HDPE water supply pipe production line and gas pipe production line by itself. They have 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. 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.
HDPE 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/ PPR 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/ PPR 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.
