Description:
- UPVC/CPVC Pipe extrusion line is a specialized manufacturing system designed for the production of cavity tubes made of unplasticized polyvinyl chloride (UPVC) or chlorinated polyvinyl chloride (CPVC). These materials are known for their durability, corrosion resistance and excellent performance in a variety of environments. Cavity tubes are commonly used in plumbing, drainage and irrigation systems.
- The extrusion line begins with the preparation of UPVC/CPVC materials. Raw materials are mixed and compounded to achieve the desired performance and consistency. The composite material is then fed into the extruder, which is the core component of the extrusion line.
- Inside the extruder, the UPVC/CPVC material is heated to a viscous state and pushed through the mold. The molds are specifically designed to shape the material into a PVC pipe structure.
- When the pipe leaves the mold, it goes through a series of cooling and calibration devices. These devices ensure that pipes maintain their shape and size as they cool and cure. The precision of the calibration process is essential to achieve the production of pipes with uniform wall thickness and smooth internal and external surfaces.
- After cooling, the cavity tubes are cut to the desired length. Additional finishing operations, such as sanding or polishing, can be applied to further enhance the aesthetics and functionality of the pipe.
- The UPVC/CPVC pipeline extrusion line offers several advantages. It produces pipes of consistent quality and precise dimensions, ensuring reliable performance in a variety of applications. The extrusion process is highly efficient and can be scaled up or down according to production requirements. In addition, the use of UPVC/CPVC materials has excellent corrosion and chemical resistance, making the cavity tubes suitable for use in harsh environments.
What’s the difference between UPVC pipe and CPVC pipe:
1. Material composition:
UPVC pipe: Made of unplasticized polyvinyl chloride, which is a type of PVC without plasticizers. This material is known for its chemical stability, durability, and corrosion resistance.
CPVC pipe: Stands for chlorinated polyvinyl chloride. It is a modified PVC that has been chlorinated, which enhances its heat resistance and chemical stability.
2. Heat resistance:
UPVC pipe: Has a lower temperature range and is generally suitable for use at temperatures around 60°C.
CPVC pipe: Has a higher temperature resistance, with a maximum use temperature of up to 93°C or even higher. This makes it suitable for hotter environments or applications that may encounter higher temperatures.
3. Pressure resistance:
UPVC pipe: Usually has a lower rated pressure and can be suitable for certain low-pressure applications.
CPVC pipe: Can withstand higher pressures, with a rated pressure usually above 25kgf/cm². This makes it a relatively good choice for high-pressure systems.
4. Applications:
UPVC pipe: Usually used in building drainage systems, water supply pipes, and other low-pressure pipe applications.
CPVC pipes: Due to their high temperature and pressure resistance, they are often used in hot water systems, industrial pipelines and other occasions with high performance requirements.
5. Cost:
In general, CPVC pipes may cost more than UPVC pipes due to their enhanced performance characteristics. However, the cost will vary depending on the specific application, size and other factors.
