HDPE and PE pipes both serve similar functions, yet they differ in a few important ways. Here, we look at the differences between HDPE and PE pipe strength, service life, corrosion resistance, and more.

HDPE pipe is a type of plastic pipe that’s used to transfer fluids and gases or to replace ageing concrete or steel mains pipelines. HDPE pipe (which stands for high-density polyethylene pipe) is flexible, highly impermeable, and suitable for high pressure pipelines. Most commonly, HDPE pipe can be seen in use for water mains, gas mains, sewer mains, slurry transfer lines, rural irrigation, fire system supply lines, electrical conduits, communication conduits and drainage pipes.
PE pipe (which stands for polyethylene pipe) is a broader term that refers to any thermoplastic pipe made from ethylene gas. PE pipe comes in numerous styles including low-density, cross-linked, ultra-low-molecular-weight, high-molecular-weight, medium-density, ultrahigh molecular weight, chlorinated, and linear low-density.
HDPE is a type of PE pipe. However, HDPE pipes are more durable than other PE pipes because they come with high melting and impact points. HDPE pipe is tough, resistant to chemicals, resistant to corrosion, and light in weight.
When comparing HDPE pipe strength to PE pipe strength, it’s important to consider the material, thickness and quality of the specific PE pipe, since PE pipe comes in a range of styles. Generally, HDPE pipe is considered a highly durable pipe, especially when jointing is considered; HDPE pipe can be joined by butt welding, electrofusion welding, socket welding or extrusion welding. These welds create a homogenous joint that is at least as strong as (if not stronger than) the existing pipe, with no need for rubber seals or jointing chemicals. As a result, HDPE pipe has a longer lifespan and is less likely to be affected by root intrusion.
In addition to durability, HDPE pipe features low thermal conductivity, meaning it can retain the normal operating temperatures despite outside factors. Unlike the ordinary PE pipes, HDPE pipes are rust-resistant and highly reliable. HDPE pipes maintain the initial flow capacity despite the prevailing environmental factors, and little to no maintenance costs are needed to keep them working.
Unlike other piping systems that corrode over time, HDPE pipe does not rot, rust or corrode. It is resistant to chemicals and biological growth, meaning the pipe has a long service life and saves money on repairs and replacement.
The life expectancy for HDPE pipe can stretch between 50 to 100 years, depending on the application, design and installation. This makes it one of the longest-lasting pipes available.
Unlike other popular pipe systems, HDPE pipe can be joined by butt welding, electrofusion welding, socket welding or extrusion welding. These welds create a homogenous joint that is at least as strong as the existing pipe and are virtually leak-free.
Most PE piping systems must be installed by digging a ditch, which results in pedestrian, traffic and environmental disruptions. HDPE can be installed using an open-cut method, or through the use of eco-friendly trenchless technology. This technology can also be used to install HDPE pipes under creeks, rivers, lakes and roads with minimal environmental disruptions.
HDPE pipe has a smaller environmental impact than most other types of PE pipe. HDPE is lightweight and more cost effective to transport than metal pipes. Due to HDPE flexibility and the use of heat fusion joints, fewer fittings are required. During trenchless installation, smaller pipe can be used which results in less ground disruption. HDPE pipe joints negate harmful leaks, and HDPE does not emit toxins into the air during production or during use. For all of these reasons, HDPE is recognized for its minimal impact on the environment.

HDPE pipe is a type of plastic pipe that’s used to transfer fluids and gases or to replace ageing concrete or steel mains pipelines.

HDPE pipe has a wide range of dredging applications. Dredging is often used to remove the buildup of deposits underwater; to clear water pathways for ships to pass; to create enough space to construct bridges dams; and to remove silt and pollutants from the bottom of lakes and rivers. HDPE pipe can be used for these tasks, as well as for the removal of sediment and debris from the bottoms of lakes, rivers, harbors, and other bodies of water. Specifically, HDPE pipe can dredge both naturally deposited sediments and man-made debris such as rocks, bottom sediments, construction debris, refuse, plant matter, and animal matter on the bottom of shallow seawater and in freshwater bodies.
HDPE pipe has many advantages that make in an excellent choice for dredging. It’s low in weight, making it easy to maneuver and transport. It is durable with a lifespan of 50 to 100 years, ensuring a good service life and a higher return on investment. It is resistant to chemicals, rust, decay, abrasion, impact and biological growth, meaning the pipe saves money in the long term on repairs and replacement. It is flexible, ductile, and has excellent resistance to fatigue. HDPE pipe also has leak-free joints, which are connected by butt welding, electrofusion welding, socket welding, or fusion. These welds create a homogenous joint that is at least as strong as (if not stronger than) the existing pipe, with no need to use rubber seals or jointing chemicals (such as is needed with PVC pipe). As a result, HDPE pipe is more environmentally friendly and has a longer lifespan. For all of these reasons, HDPE pipe is a popular choice for dredging applications.
HDPE pipe has an extremely long lifespan that can stretch up to 100 years. Due to its longevity, corrosion resistance and durability, HDPE pipe is a good candidate for resale. Used HDPE pipe comes with the benefit of being more cost effective than pipe that is sold new. Furthermore, the pipe’s popularity means it can be found in a wide range of sizes and styles. Finally, due to its durability, used HDPE pipe often performs just as well as pipe that is purchased new. Before buying new HDPE pipe for your dredging project, consider exploring the used HDPE pipe market.
