Corrosion Resistant CPVC Pipe Extrusion Line for Industrial Piping

What is C-PVC

CPVC stands for Chlorinated Polyvinyl Chloride. It is a type of thermoplastic produced by chlorinating PVC resin. The chlorination process improves the portion Chlorine from 58% to 73%. The high chlorine portion makes the features of C-PVC pipe and production processing significant different.

In the extrusion process of cpvc pipe, which points should be careful

During the extrusion process of CPVC (Chlorinated Polyvinyl Chloride) pipes, several points require careful attention to ensure the production of high-quality pipes. Here are some key points:

1. **Material Handling and Mixing**:

- Ensure proper handling and mixing of CPVC resin and additives to achieve uniform dispersion and consistency in the material. Proper mixing is crucial for maintaining the desired properties of the CPVC compound.

2. **Temperature Control**:

- Monitor and control the extrusion temperature carefully, as CPVC material has specific temperature requirements for processing. Maintain the temperature within the recommended range to prevent degradation of the material and ensure proper melt flow.

3. **Screw Design and Configuration**:

- Use extruder screws designed specifically for processing CPVC material. The screw design should provide adequate mixing and homogenization of the melt while minimizing shear heating to avoid material degradation.

4. **Die Design and Calibration**:

- Ensure the die design is suitable for CPVC pipe extrusion, with proper dimensions and geometry to produce pipes with consistent wall thickness and diameter. Calibrate the die properly to achieve uniform pipe dimensions.

5. **Cooling and Quenching**:

- Implement effective cooling and quenching systems to rapidly cool the extruded CPVC pipe and set its dimensions. Proper cooling is essential for preventing warping or distortion of the pipe and ensuring dimensional stability.

6. **Pulling and Sizing**:

- Control the pulling speed and sizing of the CPVC pipe to achieve the desired dimensions and surface finish. Proper pulling and sizing ensure uniformity in pipe diameter and wall thickness throughout the length of the pipe.

7. **Monitoring and Quality Control**:

- Implement a comprehensive monitoring and quality control system to detect any defects or inconsistencies in the extruded CPVC pipes. Conduct regular inspections and tests to ensure compliance with specifications and standards.

By carefully managing these points during the extrusion process, manufacturers can produce high-quality CPVC pipes that meet the required specifications and performance standards.

Extrusion line details:

Twin screw extruder machine

The extruder are crafted with top brand components to ensure production stability, efficiency and machine durability. Due to the stick feature of the CPVC material, we adopt 45kw for the extrusion line to ensure the pushing force. Meanwhile our screw and barrel is specially designed to deter to the high corrosive characters.

Vacuum calibration & cooling tank

The vacuum calibration tank adopt two chamber structure: the vacuum calibration and cooling parts. Both of vacuum tank and spraying cooling tank adopt stainless 304 steel. The excellent vacuum system ensures precise sizing for pipes. We lengthen the vacuum and cooling tank to 8m. With much longer cooling process, the CPVC pipe can be well cooled and have better surface.

Haul-off Unit

We adopt three caterpillar on the haul-off machine ensures produced pipe running stably and steady. The haul-off units can make tailored hauling model based on certain production requirement by adjusting the general control.

Cutting Unit

The high accuracy encoder ensures a precise and stable cutting length. With PLC control system, it can be cut by manual operation according to the specific application. Due to the high corrosive feature of the CPVC material, all the surfaces of the cutting unit adopts stainless steel 304. It ensures the working lifetime of the cutting machine.
