How are PPR pipes produced?
PPR (Polypropylene Random Copolymer) pipes are produced through a continuous extrusion process. The process begins with raw material (PP granules) being mixed with additives, then heated and forced through a die to form the pipe shape. Finally, the pipe is cooled, cut, and quality tested before being packaged
Here's a more detailed breakdown: 1. Material Preparation: Raw PP granules are mixed with additives like stabilizers, pigments, and other chemicals to enhance properties and ensure the desired color.
2. Melting and Extrusion: The mixture is heated and melted in an extruder, a machine with a rotating screw that forces the molten material through a die.
3. Cooling and Forming: The molten material exits the die as a continuous pipe, which is then cooled, typically in a water bath, to solidify the shape.
4. Post-Processing:
The pipe is cut to desired lengths and undergoes quality control checks to ensure dimensional accuracy and other specifications.

Extrusion – The production process begins with the extrusion of the PP-R and color masterbatch. The raw materials are mixed together and fed into an extruder. The extruder melts the materials and pushes the molten mixture through a die to form the shape of the PPR pipe.
