This pipe extrusion line mainly includes single screw extruder, molds, vacuum calibrating water tank, spray water cooling tank, haul-off machine, cutting machine(or winder) and overturning bracket. 
Extruder: 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 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.
Vacuum calibrating water 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. The accurate bronze calibrating sleeve ensures cooling speed and molding pipe. It can be three-dimension adjusted up & down and left & right.  
Water spray cooling tank: The body is made of stainless steel and the shade is transparent soft PVC curtain. Stainless steel float adjusts water level and electricity controls water temperature. The nozzle material is ABS engineering plastic. The frame of the machine can be adjustable up and down. There is roller in the tank.
Haul-off machine: It adopts frequency conversion. Every traction frame transfers with chain which ensures every track moving simultaneously. It is pneumatic and mechanical combination clamping. The bearing has special structure which can effectively reduce the installation error.
Cutting machine: It is automatic dustless cutting machine. Smooth cutting section, simultaneous frequency conversion drive, high accuracy and low noise.
Control system: We can offer SIEMENS PLC control system which is intelligent controlling system. Also we can offer ordinary control system which use SIEMENS electrical parts, Omron temperature controller. Intelligent control makes the operation simple.
