How Are PVC Pipes Made?
Overview of Agricultural Growth and PVC Pipe Industry
- Many countries have experienced agricultural growth and emerging infrastructure over the past two decades, with the global agricultural industry valued at $9.6 trillion in 2020, projected to reach $10.1 trillion in 2021.
- The availability of water through pipelines and a network of channels is crucial for this growth; plastic pipes play a significant role in both industrial and agricultural sectors.
- The global market for PVC pipes was valued at $54 billion in 2015, expected to rise to $85 billion by 2022.
Manufacturing Process of PVC Pipes
- The video explores the manufacturing process of plastic pipes, focusing on PVC due to its widespread use globally.
- Key raw material used is PVC resin, along with various additives such as processing acids, lubricants, colors, and fillers that are mixed together.
Steps in the Production Process
- Raw materials are loaded into a high-speed mixer where they are blended cold before being filtered to remove larger particles.
- The mixture is then heated between 150°C and 220°C in a screw cylinder until it becomes a paste; this paste is shaped into pipe form using a die head which determines the pipe's diameter.
Cooling and Quality Control
- After shaping, the pipe passes through a vacuum tank where it cools via water sprays to maintain its shape.
- Length measurement occurs during traction machine processing; pipes are printed with company name and type information before being cut automatically to required lengths.
