PE Gas/Water Supply Drain-Pipe Extrusion Line

Diameter Scope: (ID)￠20-￠800mm

PE gas/water supply pipe extrusion line introduction and features:

HUASU Machinery designed and developed HDPE/MDPE water supply drain-pipe and gas pipe production line by itself. This 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. Its have many features of low power consumption, high output, high automation and reliable production,special structure, high degree automation, and easy operation, continuous produce stable and reliable and so on. It is also applicable for high speed extrusion of PE, PP, PPR, PERT, ABS etc. 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.

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: Optimized spiral die ensure the melt distribution uniform to make the pipe wall uniform and guarantee the pipe pressure.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.

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.

Vacuum calibrating water tank: All of vacuum tank and water cooling tank is made from stainless steel, dual water supply pipe line with filtration system, water level and temperature control system and optimized positioning of the bayonet-type spray nozzles. 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.  

Control system: We can offer Siemens PLC controlling system which is intelligent controlling system. Also we can offer ordinary controlling system which use Siemens electrical parts, Omron temperature controller. Intelligent control makes the operation simpler. 

Haul-off machine: The twin or multi caterpillar haul-off unit is equipped with high quality rubber block or rubber belt(for high speed production) accuracy driving and control system ensure the speed stable and running reliable.We can offer two tracks, three tracks, four tracks, five tracks and six tracks Haul-off machine 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. 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. Large –diameter pipe uses full-automatic planetary cutting machine. It is synchronization with the whole production line. The flexibility adjustment for the blade place and cutting depth assures cutting machine reliability.
