Double Wall Corrugated HDPE/PP Pipe Extrusion Line

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.

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:

JWELL 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
• Closed pressure circulating water cooling
• ID50~ID300 specifications
• Modules are equal in width

Jwell high-speed line can produce PE (mainly recommended)/PP/PVC. At present, we provide 36 high-speed lines for customers, including 9 high-speed lines for domestic customers and 27 high-speed lines for foreign customers.
