Plastic Extrusion Equipment PP-R Hot Cold Water Supply Pipe
Extruder
extrude PPR (Polypropylene Random) pipes for both cold and hot
water applications, specialized PPR pipe extrusion equipment is
used. This equipment is designed to handle the unique properties
and requirements of PPR material. Here's an overview of the
process:
1. Raw Material Preparation: PPR raw material is typically supplied
in the form of PPR resin or granules. These materials are loaded
into the extruder hopper.
2. Extruder: The extruder is the central component of the
equipment. It consists of a barrel and a screw system. The PPR raw
material is fed into the barrel, where it is heated and melted by
the rotating screw. The screw conveys the molten PPR material
towards the die.
3. Die Head: The die head is responsible for shaping the molten PPR
material into a pipe profile. It determines the pipe's outer
diameter, wall thickness, and other specifications. The molten PPR
material passes through the die head, which imparts the desired
shape.
4. Cooling and Sizing: After exiting the die head, the newly formed
PPR pipe undergoes a cooling process to solidify it. A water
cooling system is typically used, where the pipe passes through a
water bath or spray cooling system. Sizing sleeves or vacuum tanks
may also be employed to control the pipe's dimensions and ensure
uniformity.
5. Haul-off and Cutting: Once the pipe is cooled and solidified, it
goes through a haul-off unit, which pulls the pipe at a controlled
speed. This helps maintain the desired dimensions and ensures
uniformity. The pipe is then cut to the desired length using a
cutting device, such as a saw or cutter.
6. Optional Processes: Additional processes can be incorporated
into the extrusion line based on specific requirements. These can
include pipe marking, printing, embossing, or surface treatment.
It's important to note that PPR pipes are typically produced using
a multi-layer extrusion process. The core layer consists of PPR
material, while the outer layers may include a different material
for added strength or UV resistance. The specific configuration of
the extrusion equipment may vary based on the manufacturer and the
desired specifications of the PPR pipes.
Always follow the manufacturer's guidelines and specifications for
the extrusion equipment to ensure proper operation and production
of high-quality PPR pipes.
