PPR pipe extrusion line
PPR pipe, also known as polypropylene pipe, is a new type of plastic pipe material with good corrosion resistance, high temperature resistance, impact resistance and long service life. It is widely used in building water supply and drainage, hot and cold water transportation, floor heating system and other fields.
| Model | Pipe Diameter (mm) | Output (kg/h) | Main Motor (kW) |
|---|---|---|---|
| PPR63 | 16–63 | 150–260 | 45–75 |
| PPR63 (Dual Output) | 16–63 (double output) | 250–450 | 75–132 |
| PPR110 | 20–110 | 200–330 | 55–90 |
| PPR160 | 50–160 | 250–400 | 75–110 |
The production process of PPR pipe mainly includes the following steps:
- Raw material preparation: Add PPR pipe raw material (usually polypropylene random copolymer) into the hopper.
- Feeding: Feed the raw material into the barrel of the extruder by vacuum suction or manual feeding.
- Plasticization: Under the thrust and heat of the extruder screw, the raw material melts and plasticizes into a uniform flowing melt in the barrel.
- Extrusion: The melt is extruded from the extruder die by the thrust of the screw to form a tubular blank.
- Vacuum Shaping: The tubular blank is placed in a vacuum cooling tank or a water spray cooling tank for cooling and shaping, so that it is shaped into a pipe with a certain size and shape.
- Traction: The shaped pipe is pulled out at a specified speed by a traction machine.
- Cutting: Use a cutting machine to cut the pipe into the required size according to the specified length.
- Inspection: Perform appearance inspection, size inspection, performance inspection, etc. on the cut pipe, and pack it into the warehouse after passing the inspection.
The production process parameters of PPR pipes have a great influence on product quality, mainly including the following aspects:
- Screw speed
- Barrel temperature
- Mold temperature
- Tractionspeed
- Cooling temperature
Precautions for PPR pipe production process：
- During the production process, the quality of raw materials should be strictly controlled to prevent the use of raw materials with excessive impurity content.
- Equipment such as extruders and molds should be inspected and maintained regularly to ensure that the equipment is in good working condition.
- The monitoring of production process parameters should be strengthened, and parameters should be adjusted in time to ensure stable product quality.
- Product inspection should be done well and unqualified products shall not leave the factory.
Unit specifications of PPR Pipe Extrusion Machine
Best laser printer machine
- Suitable products: Metal, plastic, ceramic, glass, wood and etc.
- Printed letter size: adjustable.
- Option: UV laser and fiber laser
There are two types of laser priter machine, one is called UV laser printer, another is called fiber laser printer. Due to the different wavelengths of light, two types laser printers are suitable for different materials and scenarios.
Clients can choose to use UV laser printer or fiber laser printer accordingly. In the extrusion field, many clients choose laser printer for their products.
Color Marking Machine Co-extruder Machine
The color marking machine in the pipe production line is a device used to add color marking lines on the surface of the pipe, which plays an important role in identification and differentiation.
PVC Pipe Belling Machine
The PVC Pipe Belling Machine plays an important role in the production of the PVC pipel ine and the installation of the pipeline system, which improves the sealing and reliability of the pipe line connection.
For example, in a building drainage pipe system, the expansion of the PVC pipe is expanded through the Belling machine, which can easily connect the pipes with the pipes such as elbow, three -links, and form a complete drainage pipe network.
