Tube and Pipe Basics: How to Get the Perfect Bend

Tube and Pipe

Tubes and pipes play a significant role in most engineering and construction projects. Whether the aim is to deliver fuel, fluids, or even gases, pipe and tube manufacturing helps a wide range of applications across many different industry sectors.

Achieving the perfect bend in a tube or pipe is an essential part of many projects. Whether you’re working with copper, PVC, metal, or any other material, knowing how to achieve this can save time and money as well as make your job easier. Here’s everything you need to know in order to bend a tube or pipe successfully.

Tube vs. Pipe: What’s the Difference?

Simply put, tubes are hollow cylindrical objects that are frequently used to transport or store liquids and gases. Pipes, on the other hand, are solid cylindrical objects that can be used for transporting those same fluids and gases, as well as electrical wiring and structural support.

Understanding the difference between tubes and pipes is important in order to know which type you’re dealing with. You should focus on the wall thickness as well as the actual material if you’re not sure.

Once that’s established, you can then take the necessary steps to bend it.

Factors to Keep in Mind to Bend a Tube or Pipe

How do you bend a tube or pipe? There are three significant factors when bending these materials – the material itself, the diameter of the tube or pipe, and how it is heated.

  • Each material has its levels of malleability and, as such, it’s important to select the best method for the task at hand.
  • The diameter is also a factor. Larger diameters typically require more heat. If you’ve got a large diameter tube or pipe to bend, make sure that you keep an eye on the heat throughout the process so as not to overheat it.
  • The final factor is how you actually bend the tube or pipe. Most commonly, this will be achieved by heating the length of the material until it’s pliable enough to put it into a position that you’re looking for. It’s important to note here that you cannot simply bend a tube or pipe at any point – you’ll need to heat the whole length for it to be malleable enough.

This complex process requires the utmost attention to detail and the best technology possible, so it’s important to work with a provider who has the necessary experience and expertise.

Tips for Bending a Tube or Pipe

Here are some of our top tips to help you on your way to being a tube and pipe bending pro.

  • Ensure that the material is as straight as possible before starting.
  • Check the outer diameter beforehand to work out how much heat will be necessary to bend it into position.  
  • Work from one end of the tube or pipe to the other to avoid trapping heat inside.
  • The heat transfer process will work best when you’re applying direct heat rather than using cool water or air which can slow things down.
  • A copper tube is particularly good for bending as it has a high malleability level, meaning that it won’t crack or break if you do bend it into the wrong position.
  • Make sure that you clean your tube or pipe before bending it to avoid contamination.

Using these tips, you should be able to bend a tube or pipe with relative ease successfully.

Where Can Tubes and Pipes Be Used?


Tubes and pipes are commonly used in the transportation of water, gas, or oil. They can also be found in buildings that use things like copper tubes to connect central heating systems. They are also used across a range of other industries, from medical to construction. Some of the most prevalent applications include:

  • Protecting and carrying electrical wires and cables.
  • Machine components.
  • Providing access to sewers and drains, by way of small pipes with inspection chambers attached at regular intervals.
  • Providing access to utility systems such as water, gas, and electricity.
  • Delivering fuel to cars.
  • Playing a structural role in buildings or homes, with things like ventilation systems often relying on copper tubing for strength and durability.  


Understanding how to bend a tube or pipe is an important skill for engineers and more general DIY enthusiasts. With the right know-how, you’ll be able to create whatever shape you need for your next project, whether it’s a water system or something else entirely.

As long as you focus on the material itself, the diameter of the tube or pipe, and how it’s heated, you should be able to achieve a good bend.
