The PE double wall corrugated pipe production line adopts special designed high efficiency screw which is specially used for polyolefin,it has the features of stable performance and high effiency.The double wall corrugated pipe production line has two independence extruders,which can realize both inside and outside layer with different material and colors.
Material of screw and barrel: 38CrMoAlA Nitriding treatment
Temperature instrumentation: ABB
Contactor: Schneider
The wall thickness adjustment of die head can be adjusted while machine is running.
Mould structure pattern: spiral split structure design, disassembling convenient
Mould style: Spiral mould
Mouth mould: 38CrMoA1A
Mould block material: Aluminum LY12
Online pipe expansion.
Mould base: 38CrMoAlA Nitriding Treatment
Corrugator is used to place and move corrugated mould. Vacuum is created to absorb outer layer into corrugated mould to form corrugate shape.
Cutting pattern: ring form cutting
Equipped with precise inspection device ensures the cutter accurately placing at the correct position of double wall corrugated pipe.
Whole cutting process is accurate and fully automatic.
The HDPE double wall corrugated pipe is generally connected by the expansion socket and the sealing ring. This can effectively prevent the impact of thermal expansion and contraction. The double wall corrugated pipe is widely used in the fields of highway, railway roadbed, subway engineering, waste landfill, tunnel, green belt, sports field and high water content caused by the slope protection and other drainage areas.
1. The double-layer on-line flare of the extruder head is designed as double screw co extrusion feed, which is extruded respectively through the double-layer die with adjustable gap.
2. PE/HDPE double wall corrugated pipe production line adopts extruding and forming process, it has the features of reliable quality and high efficiency.
3. This PE pipe making machine can achieve on-line belling.
4.The HDPE corrugated pipe making machine has the function of automatic demoulding when power is off.
5.The extruder adopt high-efficiency screw, the die head adopts double-layer spiral structure, mould die and core die being nitrided.
6.The pipe can be cut by on-line cutting machine automatically.
