Double-Wall Spiral Polyethylene Pipe

The double-wall spiral polyethylene pipe is one of the most advanced types of polyethylene pipe in the field of sewer networks, drainage, and the transmission of large-volume fluids. This type of pipe is manufactured from high-density polyethylene (HDPE) using the spiral (helical) method and, due to its special structure, is considered a very reliable option for high-flow, heavy-load projects.

In the double-wall spiral polyethylene pipe, the polyethylene profile is formed in a helical shape (spiral wound), and this creates very high strength alongside a suitable weight.

Payesh Gostar Behin Andish Co. is active in supplying various types of double-wall spiral polyethylene pipe for industrial and civil construction projects.

Structure of the Spiral Polyethylene Pipe

The double-wall spiral polyethylene pipe is made from polyethylene profiles that are wound helically around one another and welded together. This structure creates a very strong yet lightweight body.

In this type of pipe:

  • The main body is made from reinforced polyethylene
  • The spiral structure increases the ring stiffness
  • The completely smooth internal polyethylene surface is designed for smooth fluid flow

This combination gives the spiral polyethylene pipe very reliable performance in heavy-duty projects.

Features of the Double-Wall Spiral Polyethylene Pipe

Very High Strength with Reinforced Polyethylene

The use of polyethylene in the spiral structure gives this pipe very high resistance against external pressures, traffic load, and ground settlement.

Suitable for High Flow Rates

Due to its large diameters and smooth internal surface, the double-wall spiral polyethylene pipe is very suitable for transmitting large volumes of wastewater and surface water.

Stable Behavior of Polyethylene in Harsh Environments

Polyethylene is completely resistant to moisture, chemicals, and industrial wastewater, and it does not corrode over time.

Lower Weight than Concrete Pipes

Despite its large dimensions, the use of polyethylene significantly reduces the weight compared to concrete pipes and makes installation simpler.

Long Lifespan

If installed correctly, the spiral polyethylene pipe has a very long service life in infrastructure projects.

Applications of the Double-Wall Spiral Polyethylene Pipe

The spiral polyethylene pipe is usually used in large, heavy-duty projects:

  • Main urban sewer lines
  • High-flow wastewater transmission networks
  • Surface-water transmission channels
  • Industrial and urban drainage projects
  • Outlets of wastewater treatment plants
  • Highway infrastructure projects
  • Tunnels and underground structures
  • Industrial projects with a high fluid volume

In all of these applications, polyethylene plays the main role in the strength, durability, and performance of the pipe.

Advantages of Using the Spiral Polyethylene Pipe

  • Use of durable polyethylene in the pipe structure
  • Withstanding heavy loads in civil construction projects
  • Suitable for large diameters for wastewater transmission
  • Resistance to chemicals and corrosive materials
  • Reduced execution cost for large projects
  • Faster installation than concrete pipes
  • No need for heavy equipment during execution
  • Stable performance in various soil conditions
  • Reduced risk of failure in buried lines
  • Increased efficiency of sewer networks
