1. Material Feeding and Melting

The extrusion process begins with feeding PVC resin pellets into the extruder’s hopper. The extruder’s screw and barrel system melt and mix the material under precise temperature and pressure control. The material is evenly plasticized to ensure a consistent and uniform flow of the melted resin, preventing material degradation and ensuring high pipe quality.

2. Extrusion and Threading

Once the material is melted, it is forced through the die head, which shapes the material into the desired pipe form. In the case of PVC threading pipes, the die head is designed to incorporate the threading system that forms a uniform thread pattern on the pipe’s outer surface. This threading pattern ensures that the pipes will fit securely with other components during installation.

3. Cooling and Calibration

After extrusion, the PVC pipe is cooled and solidified through water baths and air cooling units. The calibration system ensures that the pipe maintains its precise diameter and wall thickness. The pipes are carefully monitored during the cooling process to prevent any deformation, ensuring they meet the required specifications.

4. Haul-Off and Cutting

The haul-off unit continuously pulls the pipe through the extrusion line at a consistent speed. This pulling mechanism prevents any deformation of the pipe and ensures that the final product maintains its shape and integrity. The cutting unit then trims the pipes to the desired lengths with high precision, ensuring clean cuts with minimal material loss.

5. Quality Control and Packaging

After the pipes are cut, they undergo a quality inspection to ensure they meet the required standards for size, threading accuracy, and overall quality. Any defective pipes are rejected, and the remaining pipes are automatically packaged for shipment. The extrusion line can be integrated with an automated packaging system to streamline the process, ensuring that the finished pipes are securely packed and ready for delivery.

1. Electrical Conduit Systems

PVC threading pipes are widely used in electrical conduit systems for protecting wiring and cables. The pipes' excellent electrical insulation properties make them ideal for safely enclosing electrical wires and preventing electrical hazards. The precision threading ensures a tight, secure fit with other fittings, contributing to a robust and reliable electrical infrastructure.

2. Plumbing and Water Supply Systems

PVC threading pipes are commonly used in plumbing applications for both residential and commercial water supply systems. These pipes are resistant to corrosion, chemicals, and high-pressure conditions, making them a durable solution for delivering water and other fluids. The precision threading ensures easy connection with other plumbing components, reducing the risk of leaks.

3. Telecommunications and Data Systems

In telecommunications and data systems, PVC threading pipes are used to protect cables and wiring from environmental damage. Their insulating properties and resistance to external factors such as moisture, UV radiation, and chemicals make them ideal for safeguarding sensitive communication lines.

4. Industrial Piping Systems

PVC threading pipes are also used in various industrial applications, including the transportation of gases, liquids, and chemicals. The strong mechanical properties of PVC, combined with the precise threading, make these pipes suitable for high-pressure systems and environments where reliability and safety are critical.
