China Big Plastic Pipe HDPE Structured Wall Pipe Weholite Extrusion Line

Big plastic pipe hdpe structured wall pipe weholite Extrusion line
Qingdao Huashida Machinery Co., Ltd. absorbs German advanced technology and developed the complete production line with independent intellectual property rights- spiral structured wall HDPE pipe production line
The performance of the HDPE structured wall pipe production line has reached the international advanced level.
The line is highly automated, controlled by Siemens PLC controlling system.

It can produce big plastic pipes ranging from 200-3000mm.
The HDPE spiral pipes are connected by using special pipe fittings (electric fusion sleeve, heat shrink sleeve), which are convenient and economical in construction.

Features of Weholite Structured Wall HDPE Pipe
1). High Ring Stiffness
2). High Brunt Intensity and low weight
3). Good creep deformation resistance.
4). Outer pressure resistance.
5). Erosion resistance ( such as acid, alkali and salt etc. )
6). Long life of approximately 50 years.
Applications of HDPE structured wall pipe:
- Storm Water Management./ Storm water Attenuation Application / Storm water pipelines.- Sewerage Pipelines
- Drainage Pipelines
- Culverts.
- Pipe rehabilitations.
- Landfill drainage/Leachate.
- Mine drainage.
- HDPE manholes. / Manhole Drops
- Floats
- Irrigation
Technical process:
Raw materials→Mixing→Vacuum feeding→Material drying→Single screw extrusion →Calibration→Spray cooling→Caterpillar traction→Single screw glue extrusion →Winding and forming→water cooling→cutter→pipe bracket→inspecting &packing.
The complete production line includes two parts:
1.The first part is PE Pipe extrusion line to extrude the PE/PP Square Shaped Pipe ( according to customers' requirements ).
Single Screw Extruder
Die Head (mold and mandrill)
Calibrator
Vacuum calibration&cooling Tank
Spray Cooling Tank
Haul-off
2. The second part is Spiral forming line to form and weld the big pipe.
Single Screw Extruder
Die Head
Spiral forming unit
Cutter
Bracket
High-efficiency single screw extruder
The extruder is equipped with the forced water-cooling feeding section and slotted barrel, which makes the power consumption of the main drive motor greatly reduced.

Spiral forming machine
Spiral spinning forming, exquisite structure, unique design, ensuring high product quality.
Control System
PLC computer control system with touch screen:
With super high speed and large storage capacity.
Multi points control: pipe extrusion, adhesive extrusion, winding and cutting process can be controlled synchronously or separately.
