DOUBLE WALL CORRUGATED HDPE/PP PIPE EXTRUSION LINE
DOUBLE WALL CORRUGATED HDPE/PP PIPE EXTRUSION LINE
Double Wall Corrugated HDPE/PP Pipe Extrusion Line is designed for the efficient production of high-quality double-wall corrugated pipes made from HDPE or PP materials.
Advantages and selling points of high-speed lines
1. Fixed center height
No adjustment required when changing specifications, easy to operate
Changing specifications only requires loosening one screw
The module width, installation dimensions, and operation methods are the same. The modules are completely universal, the equipment investment and maintenance costs are lower, and the production organization is flexible.
2. Double gear drive, independent running track
The driving gear is changed from a single gear drive to a double gear drive, so that the upper and lower sides of the sliding seat are stressed at the same time, which reduces the uneven force during operation and makes the module operation more stable.
The two tracks operate independently, and the equipment can operate stably for a long time in any state.
3. Add a special tractor
The signal control of the tractor comes from the cutting machine, ensuring the synchronization and accuracy of the pipe cutting moment; reducing miscutting;
Provide forward force for the pipe, effectively reduce the load of the molding machine, and prevent the molding machine from over-current shutdown protection;
Prevent the backlog of pipes, effectively avoid the expansion and deformation of the produced pipes, and ensure the stability of production.
4. Cooling water circulation
The module is fully sealed with pressure water cooling, which prevents leakage and rust, extending the service life of the equipment.
The cooling water circulation system is changed from a single-row roller chain to a double-row roller chain, which makes the pipeline circulation more stable and the pipe socket no longer tilts.
5. Stacker weighing system
During the production process, individual pipes are weighed in real time and the meter weight of the pipe is monitored.
high-speed line model introduction

SN4、SN6.3、SN8、SN10、SN12.5、SN16
PE：SN4-8
Domestic SN8 accounts for 60-70%, foreign SN8 accounts for 80-90%
Replacement: module/sizing sleeve.
PP: SN8-16 more in Russia
Obtained by replacing materials.
Pipe specifications: (GB/T 19472.1-2019)
Generally speaking, the common specifications of PE and PP double-wall corrugated pipes are based on the inner diameter series:
ID100, ID200, ID300, ID400, ID500, ID600, ID800, ID1000, ID1200, ID1500, and ID125, ID150, ID225, ID250, and those less than 100 include ID50, ID75, ID90, etc.
Commonly used in Europe, America and Australia: ID225, ID300, ID315, ID375, ID450, ID525, ID600, ID700, ID900, ID1050.
Outer diameter series: commonly used OD110, OD160, OD315, etc., similar to PVC.
According to the model, it is divided into 150 molding machines and 1000 molding machines.
Production line specifications:
high-speed lines mainly include 150, 300, 600, 800, 1000, 1200 and 1500 models.
Models are named according to production range:
150 lines: ID50~ID150 Number of module pairs: 28 pairs Center height: 1050
300 lines: ID90~ID300 Number of module pairs: 36 pairs Center height: 1050
New 300 lines: ID50~ID300 Number of module pairs: 36 pairs Center height: 1050
600 lines: ID100~ID600 Number of module pairs: 36 pairs Center height: 1260
800 lines: ID200~ID800 Number of module pairs: 36/38 pairs Center height: 1410
1000 lines: ID300~ID1000 Number of module pairs: 38 pairs Center height: 1500
1200 lines: ID400~ID1200 Number of module pairs: 38 pairs Center height: 1600
1500 lines: ID600~ID1500 Number of module pairs: 38 pairs Center height: 1900
The modules are universal and all modules have the same width.
The production line consists of:
Extruder, mold, molding machine, spray box, tractor, cutting machine, turning frame.
Chain machine
The center height is not fixed
The maximum linear speed of the molding machine is 3 meters/minute
Changing specifications and re-adjustment makes operation inconvenient.
The module is open water-cooled, which relies on gravity to circulate slowly, and the cooling is correspondingly slow. It is cooled by water spray and is prone to overflow and splashing.
Main models: 250, 400, 500 and below specifications
High speed machine
fixed center height
The maximum linear speed of the molding machine is 7.5 meters/minute
No adjustment required when changing specifications, easy to operate
Closed pressure circulating water cooling
ID100~ID1500 specifications
Modules are equal in width
Ultra high speed machine
fixed center height
The maximum linear speed of the molding machine is 20 meters/minute
No adjustment required when changing specifications, easy to operate
