Sevenstars Double Wall Corrugated Pipe Extrusion Production Line Drain-pipe Making Machine

The Sevenstars Double Wall Corrugated Pipe Extrusion Production Line is a high-quality machine designed to produce durable and reliable drain pipes. Made by Sevenstars Machinery, this equipment is perfect for factories and businesses that need to make double wall corrugated pipes efficiently and with consistent quality. These pipes are widely used in drainage systems, construction, agriculture, and other industries where strong, flexible, and long-lasting pipes are essential.

This production line uses advanced technology to create double wall corrugated pipes, which means the pipes have a smooth inner wall and a corrugated outer wall. The smooth inner wall helps water or other fluids flow easily without blockage, while the corrugated outer wall adds strength and flexibility. This design makes the pipes ideal for carrying water or drainage materials underground or in places where pipes must bend or withstand pressure from soil or heavy loads.

The Sevenstars Double Wall Corrugated Pipe Extrusion Production Line includes several important parts: an extruder, a corrugated mold, a vacuum tank, a haul-off machine, a cutter, and a stacking system. The extruder heats and melts plastic raw materials, usually high-density polyethylene (HDPE), then pushes the melted plastic through the die to form the pipe’s shape. The corrugated mold shapes the outside of the pipe while the vacuum tank cools and solidifies it quickly. The haul-off machine pulls the pipe forward at the right speed, making sure the pipe keeps its shape. The cutter then cuts the finished pipe into the right lengths, and the stacking system organizes the pipes for easy collection.

One of the main benefits of this production line is that it can produce pipes in different sizes and thicknesses, depending on the customer's needs. It is also designed to work steadily and with high precision, reducing waste and saving materials. The machine is easy to operate and maintain, helping businesses lower their operating costs and improve production efficiency.

Sevenstars Machinery is known for making reliable and durable equipment, and this double wall corrugated pipe production line is no exception. It uses quality parts and modern control systems to ensure stable performance over long periods. Whether you are starting a new pipe manufacturing business or upgrading your current equipment, the Sevenstars Double Wall Corrugated Pipe Extrusion Production Line is a smart choice to help you produce top-quality drain pipes that meet industry standards

Final product and application

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

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

Double-wall corrugated pipe has many advantages:

high strength,  lightweight, environmental protection, easy installation, strong adaptability

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
