Sevenstars 200-600mm DWC Production Line HDPE Double Wall Corrugated Pipe Plastic Pipe Extrusion Line

The Sevenstars 200-600mm DWC Production Line is a high-quality plastic pipe extrusion system designed to produce double wall corrugated (DWC) pipes made from HDPE (high-density polyethylene). Manufactured by Sevenstars Machinery, this production line is known for its efficiency, reliability, and ease of use, making it an excellent choice for companies looking to produce strong, durable plastic pipes for various applications.

This production line specializes in making double wall corrugated pipes, which are widely used in drainage, sewage, cable protection, and other underground piping systems. The pipes produced have a smooth inner wall and a corrugated outer wall, combining strength with flexibility. This design allows for resistance to heavy loads while keeping the pipe lightweight and easy to install.

The Sevenstars 200-600mm DWC Production Line covers a wide pipe size range from 200mm to 600mm in diameter. This flexibility means manufacturers can produce pipes suited for various projects, from small residential drainage systems to large infrastructure works. The production line is equipped with advanced machines that work together seamlessly. Key components include an extruder that melts and shapes the HDPE plastic, an extrusion die that forms the pipe's shape, a calibrator to maintain pipe dimensions, a vacuum system that shapes the corrugations, and a cutter to cut the finished pipes to the desired lengths.

One of the main strengths of this production line is its high production speed and stable operation. The Sevenstars Machinery brand ensures the production equipment is made with quality components and advanced technology, which helps reduce downtime and maintenance costs. The system is also easy to operate thanks to its user-friendly control panel and automated features. This allows even operators with basic training to run the production line efficiently.

Besides performance, the production line focuses on producing environmentally friendly pipes. HDPE is a recyclable material, and the manufacturing process uses less energy compared to traditional pipe production methods. Pipes made with this line have excellent resistance to chemicals, corrosion, and weathering, which guarantees a long service life.

The Sevenstars 200-600mm DWC Production Line by Sevenstars Machinery is a reliable and versatile solution for producing high-quality HDPE double wall corrugated pipes. Its combination of strong construction, efficient operation, and flexible output sizes makes it a valuable investment for plastic pipe manufacturers seeking to meet growing market demands

Double wall corrugated pipe Display

 1. Double-wall corrugated pipe is a new type of pipe with a ring-shaped outer wall and a smooth inner wall. It was first successfully developed in Germany in the early 1980s. After more than ten years of development and improvement, it has evolved from a single variety to a complete product series

 2. The production process and usage technology are already very mature. In China, the promotion and application of HDPE double-wall corrugated pipes are in an upward trend, and all technical indicators have reached the usage standards

 3. Double-wall corrugated pipe has many advantages: high strength, lightweight, environmental protection, easy installation and strong adaptability

 4. Double-wall corrugated pipe can be used for drainage pipes in municipal engineering, construction engineering, industry, agriculture, mines, etc. It can also be used as a protective sleeve for communication cables and optical cables. The perforated double wall corrugated pipe can be used as a seepage pipe and drainage pipe for saline alkali highways
