The process of manufacturing PVC pipes goes something like this:
- Preparation. The first step is prepare the ingredients for the pipes. PVC is a produced by the chemical bonding of vinyl and chloride (the 'V' and the 'C'). After this is completed, excess gas and water is removed using a centrifuge.
- Additives. In order to make the pipe different colours, and to produce PVC of different strengths and rigidity, additives are added to the basic PVC mix.
- When the mixture is complete, it is then heated to melting point before being rolled and shaped in the required pipe shape and thickness.
This is a very simple explanation of how the pipes are produced. Here is a more detailed flowchart for the entire process from design to completion of manufacturing:
