HDPE Structured Wall Pipe

About Rendifield HDPE structured wall pipe

HDPE Structured Wall Pipe offers the latest advancements in material and manufacturing technology. Raw material properties and product technology have been combined successfully to provide a light-weight engineered pipe for various gravity and non-pressure applications in the municipal, industrial, road construction, rehabilitation and marine pipeline applications.

HDPE Structured Wall Pipe is now considered the front runner in replacing traditional pipe system materials like concrete, CMP (corrugated metal pipe) and PVC (polyvinylchloride).

What is HDPE structured wall pipe?

HDPE Structured wall pipe is a type of plastic pipe that is made from high-density polyethylene (HDPE). It is characterized by its spirally wound construction, which gives it a high degree of strength and flexibility.

HDPE structured wall pipe physical properties

Rendifield HDPE structured wall pipe has a number of physical properties that make it a good choice for a variety of applications. These properties include:

  • High strength: HDPE structured wall pipe is strong enough to withstand a wide range of forces, including ground movement, soil pressure, and traffic loads.
  • Flexibility: HDPE structured wall pipe is flexible enough to accommodate changes in soil conditions and ground movement. This makes it a good choice for applications where the pipe is likely to be subjected to movement, such as in areas with seismic activity.
  • Chemical resistance: HDPE structured wall pipe is resistant to a wide range of chemicals, including acids, bases, and solvents. This makes it a good choice for applications where the pipe will be in contact with chemicals, such as in water and wastewater treatment systems.
  • Durability: HDPE structured wall pipe is durable and can withstand a wide range of environmental conditions, including UV radiation, extreme temperatures, and moisture. This makes it a good choice for applications where the pipe will be exposed to the elements, such as in outdoor drainage systems.
  • Lightweight: HDPE structured wall pipe is lightweight, which makes it easy to transport and install. This can save time and money on construction projects.

Overall, Rendifield HDPE structured wall pipe is a versatile and reliable material that can be used in a variety of applications. It is a good choice for projects where strength, flexibility, chemical resistance, durability, and lightweight are important considerations.

Here are some additional physical properties of HDPE structured wall pipe:

  • Density: 0.94 to 0.96 g/cm³
  • Specific gravity: 0.94 to 0.96
  • Tensile strength: 25 to 35 MPa
  • Yield strength: 15 to 20 MPa
  • Elongation at break: 400 to 600%
  • Coefficient of thermal expansion: 120 to 140 × 10⁻⁶ m/m/°C

HDPE structured wall pipe specifications

Pipes can be manufactured in different sizes – 300mm up to 1500mm – and in different ring stiffness’s.  All structured wall pipes are manufactured in accordance with SANS 21138 and forms part of ISO 9001: 2015 quality management system.

HDPE structured wall pipe dimensions

The dimensions of HDPE structured wall pipe vary depending on the manufacturer and the specific application. However, in general, HDPE structured wall pipe is available in diameters ranging from 300mm to 1500mm and ring stiffness of 4kN/m² or 8kN/m².

The following table shows some typical dimensions for HDPE structured wall pipe:

Diameter (mm) Ring Stiffness (kN/m²)
300 4
400 4
500 4
600 4
700 4
800 4
900 4
1000 4
1200 4
1500 4

It is important to note that these are just typical dimensions and the actual dimensions may vary depending on the manufacturer and the specific application. It is always best to consult with the manufacturer to determine the specific dimensions of the HDPE structured wall pipe that is required for your application.

In addition to the dimensions, there are a number of other factors that should be considered when selecting HDPE structured wall pipe for a particular application. These factors include:

  • The type of fluid that will be transported through the pipe
  • The pressure and temperature of the fluid
  • The soil conditions where the pipe will be installed
  • The environmental conditions where the pipe will be exposed

By considering all of these factors, you can select the right HDPE structured wall pipe for your application and ensure that it will provide many years of reliable service.
