Types of HDPE Pipe Fusion

Types of HDPE Pipe Fusion

HDPE piping provides durable, long-lasting options for many piping applications. Highly customizable, HDPE piping can be applied using various pipe sizes and fusion techniques. These fusion techniques make HDPE piping unique, allowing long pipe stretches to connect and maneuver through complex spaces. US FUSION provides tailored solutions to meet your needs through HDPE pipe fusion. 

What is Pipe Fusion?

In most piping applications, a single section of HDPE pipe will not get the job done. When multiple pieces of pipe are needed, HDPE pipe fusion comes in. While there are many types of HDPE pipe fusion, each involves heating the pipe and applying pressure to fuse two pieces together. In doing so, HDPE pipe fusion ensures long stretches of pipe are securely fused, resulting in a continuous, sealed connection. 

At US FUSION, our on-site plastic fusion team is highly skilled in HDPE pipe fusion methods. Whether your piping is underground or exposed, we focus on safety for both our crew and for the environment. We’ll ensure your pipe connections are strong and sealed properly, keeping unwanted elements out of the environment — all while meeting the highest industry standards and environmental regulations. 

4 Types of HDPE Pipe Fusion

Not sure what fusion method is needed for your project? We’ve got you covered. Below we’ll break down HDPE pipe fusion and application methods.  

Butt Fusion

Butt fusion is used when two straight pieces of pipe need to be fused together. Butt fusion is the most common and best pipe fusion method. In this method, a fusion machine holds two pieces of pipe while the ends are heated with a heater plate. Once heated, force is used to push the two ends together where they are left to cool. After the cooling process is complete, the two pieces of pipe are firmly connected and sealed. The butt fusion weld will then be stronger than the pipe. 

Electrofusion

Electrofusion is used in tight spaces and with fittings where butt fusion cannot be used. Electrofusion couplers are needed to make this fusion connection. In this method, electrofusion couplers have copper coils inside the coupler that are then heated up to fuse to the pipe together to create a tight seal. 

Socket Fusion

When flexibility is vital, socket fusion is used. Socket fusion involves heating the outside of a pipe while simultaneously heating the end of a socket. Once each piece is heated to the ideal temperature, the socket is then inserted into the pipe. As the two pieces cool, the connection is sealed, and flexibility remains. 

Saddle Fusion

Saddle fusion connects the concave portion of a pipe to an inverse saddle fitting. To get a precise connection, both the concave portion of the pipe and the saddle fitting are heated. Once heated, the two pieces are joined together using force, and the piping is then allowed to cool under pressure. This heat/pressure method creates a tight seal at a complex connection point.

What Is HDPE Piping?

What Is HDPE Piping?

HDPE piping is one of the things we do best here at US FUSION — but if you’re not working with it every day like we are, you may have some questions about what it is and how it works.

Below, we’ll explore the answers to some of those questions, giving you an overview of everything you need to know about HDPE piping: what it is, what it’s used for, and how it can benefit your application.

What Is HDPE Piping?

First things first — HDPE stands for high-density polyethylene, which is a type of thermoplastic made from petroleum. It’s flexible, but that definitely doesn’t mean it lacks in strength or performance. Among other things, HDPE is known for its outstanding water, chemical, and impact resistance — all qualities that come together to make it a top material choice for a number of applications, including heavy-duty piping.

What Is HDPE Piping Used For?

HDPE piping is corrosion and abrasion-resistant, making it a great material for transporting various solids, liquids, and gases safely and effectively. You can find HDPE piping being used for many industrial applications, some of the most common being:

  • Municipal and industrial water and waste
  • Potable water
  • Wastewater and sewer
  • Drainage
  • Firewater
  • Oil and gas gathering systems
  • Methane recovery systems
  • Landfills
  • Water supply lines for oil recovery

The bottom line is, from firewater to hazardous waste, there is no system more effective at safely containing and transporting material than HDPE piping.

What Are the Benefits of HDPE Piping?

In recent years, HDPE piping has grown in popularity in various industries — and for good reason. Many have come to realize the countless benefits it brings, including:

HDPE Piping is Durable

Arguably the greatest benefit of HDPE piping is its exceptional durability. It offers water, temperature, and corrosion resistance — three things that other types of piping (galvanized steel, PVC, copper) just can’t do. Depending on how it’s applied, designed, and installed, HDPE piping can last an astounding 50-100 years.

It’s More Affordable Than Other Options on the Market

Since HDPE piping is made of plastic, it’s much more lightweight than other types of piping. This means that it usually costs less to manufacture, transport, and install. It can also help save money and resources in regards to reduced installation time and labor.

It Delivers High Performance Across Applications

One of the biggest issues you may face with other piping systems is leaks. However, HDPE’s installation and fusion process lends itself to unparalleled leak-free performance. The fusions create a monolithic connection and are even capable of handling the frequent surges common in water distribution and oil transportation.

Easy to Repair and Maintain

On the off chance that your HDPE piping does have performance issues, due to aging or normal wear and tear, repairs are simple. Electrofusion couplers and off carriage butt welds can be performed in tight conditions to repair HDPE pipe. With trenchless techniques and technologies, HDPE pipe can be used to repair failing steel, concrete, and ductile iron pipelines. If it’s time to replace or upsize your existing piping system, whether it’s an HDPE system or not, HDPE piping makes it easier than ever.

HDPE is a Sustainable Piping Option

For multiple reasons, HDPE piping is a fairly sustainable option. It takes less energy to manufacture than non-plastic pipes, requires fewer fittings due to its flexibility, and prevents hazardous toxins from escaping into the environment. It’s also capable of being recycled into non-pressure piping applications.

How Is HDPE Piping Installed?

HDPE pipes can be installed through two techniques: trenching and trenchless. Trenching involves digging deep trenches, then installing the pipe. It’s messier than the trenchless technique, but it works more effectively for certain applications.

Trenchless installation, as the name suggests, doesn’t require digging any trenches before the pipes can be installed. It makes use of many different techniques to get the job done, such as directional drilling, sliplining, and pull-in-place lining.
