The UPVC/CPVC Pipe Extrusion Line is a specialized manufacturing system designed for the production of cavity pipes made from Unplasticized Polyvinyl Chloride (UPVC) or Chlorinated Polyvinyl Chloride (CPVC). These materials are known for their durability, corrosion resistance, and excellent performance in various environments. Cavity pipes are commonly used in plumbing, drainage, and irrigation systems.

The extrusion line begins with the preparation of the UPVC/CPVC material. The raw materials are mixed and compounded to achieve the desired properties and consistency. The compounded material is then fed into the extruder, the core component of the extrusion line.

Inside the extruder, the UPVC/CPVC material is heated to a viscous state and pushed through a die. The die is specifically designed to shape the material into the PVC pipe structure.

As the pipe exits the die, it passes through a series of cooling and calibration devices. These devices ensure that the pipe maintains its shape and dimensions as it cools and solidifies. The precision of the calibration process is crucial to achieving pipes with uniform wall thickness and smooth inner and outer surfaces.

After cooling, the cavity pipes are cut to the required lengths. Additional finishing operations, such as sanding or polishing, may be applied to further enhance the aesthetics and functionality of the pipes.

The UPVC/CPVC Pipe Extrusion Line offers several advantages. It produces pipes with consistent quality and precise dimensions, ensuring reliable performance in various applications. The extrusion process is highly efficient and can be scaled up or down based on production requirements. Furthermore, the use of UPVC/CPVC materials provides excellent resistance to corrosion and chemicals, making the cavity pipes suitable for use in harsh environments.

What’s the difference between UPVC pipe and CPVC pipe:
1.Material Composition:
UPVC pipe: Is made from unplasticized polyvinyl chloride, a type of PVC that does not contain plasticizers. This material is known for its chemical stability, durability, and resistance to corrosion.
CPVC pipe: Stands for chlorinated polyvinyl chloride. It is a modified version of PVC that has been chlorinated, enhancing its heat resistance and chemical stability.

2.Temperature Resistance:
UPVC pipe: Has a lower temperature range, typically suitable for use in temperatures up to around 60°C.
CPVC pipe: Offers a higher temperature resistance, with a maximum use temperature of 93°C or even higher. This makes it suitable for hotter environments or applications where higher temperatures may be encountered.

3.Pressure Resistance:
UPVC pipe: Typically has a lower pressure rating, making it suitable for certain low-pressure applications.
CPVC pipe: Can withstand higher pressures, with a pressure rating typically above 25kgf/cm². This makes it a good choice for high-pressure systems.

UPVC pipe: Is commonly used in building drainage systems, water supply lines, and other low-pressure plumbing applications.
CPVC pipe: Due to its higher temperature and pressure resistance, it is often used in hot water systems, industrial piping, and other applications where higher performance is required.

Generally, CPVC pipe may cost more than UPVC pipe due to its enhanced performance characteristics. However, the cost can vary depending on the specific application, size, and other factors.
