It is widely used in producing HDPE water supply pipes, gas supply pipes. It can make HDPE pipes with diameter from 16mm to 800mm. With many years of plastic machinery development and design experience, this HDPE pipe extrusion line has the unique structure, the design is novel, the equipment entire line layout is reasonable, the control performance is reliable. By different requirement, this HDPE pipe line could be designed as multiply-layer pipe extrusion line.
The extruder of HDPE pipe line adopt high efficiency screw & barrel, the gearbox is hardening teeth gearbox with self-lubrication system. The motor adopt Siemens standard motor and speed controlled by ABB inverter. The control system adopts Siemens PLC control or button control.
This PE pipe line is composed by: material charger+ SJ90 Single screw extruder + pipe mold + vacuum calibration tank + spraying cooling tank x 2sets + three caterpillar haul-off machine + no-dust cutter+ stacker.
The tank body of vacuum calibration tank adopt two chamber structure: the vacuum calibration and cooling parts. Both of vacuum tank and spraying cooling tank adopt stainless steel 304#. The excellent vacuum system ensures the precise sizing for pipes; spraying cooling will improve the cooling efficiency; Auto water temperature control system make the machine more intelligent.
The haul-off machine of this pipe line will adopt caterpillars type. With meter code, it can count the pipe length during the production. Cutting system adopt no-dust cutter with PLC control system.
SJSZ series conical twin screw extruder is mainly composed of barrel screw, gear transmission system, quantitative feeding, vacuum exhaust, heating, cooling and electrical control components Etc. The conical twin screw extruder is suitable for producing PVC products from mixed powder.
It is special equipment for PVC powder or WPC powder extrusion. It has advantages of good compounding, large output, stable running, long service life. With different mould and downstream equipment, it can produce PVC pipes, PVC ceilings, PVC window profiles, PVC sheet, WPC decking, PVC granules and so on.
Different quantities of screws, double screw extruder have two screws, sigle screw extruder only have one screw, They are used for different materials, double screw extruder usually used for hard PVC, single screw used for PP/PE. Double screw extruder can produce PVC pipes, profiles and PVC granules. And single extruder can produce PP/PE pipes and granules.
It is mainly used for extruding thermoplastics, such as PE, PP, PS, PVC, ABS, PC, PET and other plastic material. With relevant downstream equipment (including moud), it can produce various kinds of plastic products, for example plastic pipes, profiles, panel, sheet, plastic granules and so on.
SJ series single screw extruder has advantages of high output, excellent plasticization, low energy consumption, stable running. The gearbox of single screw extruder adopt high torque gear box, which has features of low noisy, high carrying capacity, long service life; the sccrew and barrel adopt 38CrMoAlA material, with nitriding treatment; the motor adopt Siemens standard motor; inverter adopt ABB inverter; temperature controller adopt Omron/RKC; Low pressure electrics adopt Schneider electrics.
