As a buyer of industrial products, you want to ensure that you make an informed decision. This is especially true for pipes, a critical component in various industries. HDPE pipes are among the most versatile and widely used types of pipes. In this guide, you’ll learn everything you need to know about HDPE pipes, including their types, sizes, and uses.

What are HDPE Pipes?

High-Density Polyethylene (HDPE) is a type of plastic made from high-density polyethylene resin. HDPE pipes are strong, durable, and flexible, making them an ideal choice for many applications. These pipes are also resistant to corrosion, chemicals, and UV rays, making them ideal for harsh environments.

Grading HDPE Pipes

HDPE pipes come in various types, each designed for specific applications. The most common types of HDPE pipes include the following.

  • For lower pressure requirements, piping systems can be made using PE 32 or PE 40.
  • PE 63 grade HDPE pipe is used for medium pressure requirements.
  • PE 80-RC is made from a material resistant to crack propagation and used in applications prone to cracking, such as sewage systems and water distribution networks.
  • PE 100-RC: This type is made from a material that is resistant to crack propagation and has a minimum required strength of 100 N/mm2.

According to European standards, these pipes are classified based on the pressure-holding capacity, ranging from nominal pressure PN class to PN20, which holds up to 20 bar pressure. You can identify them with their dedicated colour codes- Yellow for PN4, Red for PN6, Blue for PN10, and Green for PN16.

Sizes of HDPE Pipes

HDPE pipes come in various sizes, ranging from 20 mm to 1200 mm in diameter. The size of the pipe is determined by its internal diameter and is measured in millimetres. When choosing the right size of HDPE pipe, consider the volume of fluid that needs to be transported, the pressure that the fluid is subjected to, and the length of the pipeline.

Uses of HDPE Pipes

HDPE pipes are used in a wide range of applications, including:

Water supply:

HDPE pipes are used in the water distribution. Depending on the supply area, distribution network, and other factors, you can select a suitable pipe. PN 10 grade pipe is suitable for water supply in a multistory apartment.

Gas distribution

HDPE pipes are used in the gas distribution industry for natural gas and propane gas. This requires high tolerance to pressure, which PN-16 to PN-2 grade pipes can fulfil depending on your operation.


HDPE pipes are used in the sewerage industry for sewage and stormwater. They are resistant to corrosion, chemicals, and UV rays, making them ideal for harsh environments.


HDPE pipes are highly used in the agriculture industry for irrigation and drainage. Depending on the pump used, you can select from a range of pressure gradient pipes.


HDPE pipes are used in the mining industry for dewatering and slurry transport. They are resistant to abrasion and impact, making them ideal for use in harsh environments.


HDPE pipes are used for cable protection in the telecom industry, as they provide a durable and cost-effective solution for protecting underground cables. General PN class pipes can be used for such purposes.

Advantages of HDPE Pipes

HDPE pipes have many advantages over traditional pipes made of materials such as concrete, steel, or PVC. Benefits of HDPE pipes include:


HDPE pipes are extremely durable and can last for decades without any maintenance. They are resistant to corrosion, chemicals, and UV rays.

Low cost

HDPE pipes are cost-effective compared to other piping materials.


HDPE pipes are much lighter than traditional pipes, making them easier to handle and transport.


HDPE pipes are extremely flexible, making them ideal for use in areas with a risk of soil movement or shifting. They are also easier to install compared to rigid pipes.

Easy installation

HDPE pipes can be joined together using heat fusion. They are easy to install and quick, without needing specialist tools or equipment.

HDPE pipes are a versatile and durable choice for a wide range of applications. They offer many advantages over traditional pipes made of concrete, steel, or PVC, including their low cost, lightweight, flexibility, and easy installation. Whether you are looking to install a water and sewage system, distribute natural gas, transport slurry in the mining industry, or irrigate crops, HDPE pipes are the ideal solution. Hope this article was a helpful guide to HDPE pipes for your business needs.
