Hydraulic Tube Bender Comparison Guide

Hydraulic Tube Bender

In the manufacturing or metal processing industries, hydraulic tube benders are required to achieve precise bending without wrinkles. You can set the desired bending angle through specific settings in this device. They can help you create accurate elbows. These hydraulically driven bending tools can provide you with different sockets so that you can produce electrical or metal pipes that are bent to the desired angle.

Whether you need to bend metal pipes, pipes, or conduits, hydraulic tube benders are your ideal tool. But what type of pipe bender do you need? The answer depends on what you want to bend and how to bend it. In this article, we will take a look at different types of tube benders.


Differences between pipe, tube, and conduit benders

  • Pipe Bender: So how do pipes differ from tubes? According to common wisdom, a pipe is determined in referring to its inner diameter vs. its outer diameter, and its wall thickness. A pipe is round and has walls usually thicker than a drain.

  • Tube bender: A tube bender bends tubing and is mostly the same method as a bender for pipes. And how do tubes differ from pipes? A tube is defined by its outer diameter and is typically smaller and less rigid than a pipe, according to the same conventional wisdom. It may be round, or not.

  • Conduit bender: A conduit bender is built to bend angles in the conduit, a tube through which electrical wiring is performed. It is necessary to understand the difference between a pipe and a tube to select a compatible bender and die, former or bender roller of the right size.

Hydraulic, electric, manual, and mechanical

The four most common types of pipe benders are hydraulic tube benders, electric, manual, and mechanical. The hydraulic unit is extremely durable and strong and can produce precise angles with thick walls in large pipes. Electric pipe benders have electric gear drives and are usually programmable, making them ideal for producing multiple iterations of the same bend. Manual or manual pipe benders are cheap, easy to transport and manipulate, and can complete many bending tasks with sufficient elbow grease. Manual bending is an art form. It requires some skill but allows you to make custom shapes. In terms of bending angles, mechanical benders are between hydraulic benders and manual benders.

Applications of hydraulic tube benders

The highly versatile hydraulic bender can be used in many fields, from automotive hydraulics to interior design. Some examples of finished products that can be produced using 1 to 12 axis pipe benders, depending on the degree of automation required. Some of the applications include:

  • Hydraulic connections and systems
  • Fuel pipes for diesel motors
  • Motorbike and scooter accessories
  • Iron, steel and aluminum furnishings and accessories
  • Furnishings for shops, office buildings, hospitals, etc.
  • Children’s playgrounds & gym equipment
  • Exhausts
  • Handles
  • Equipment for the food industry

How to operate a manual hydraulic tube bender?

The manual bender is a relatively simple tool that can provide precise and reliable bends on different pipes including copper pipes, steel pipes, and pipes based on aluminum. Although there are many automatic pipe benders that can be driven electrically and hydraulically, these machines are bulky and not suitable for field applications where proper power connections may not be available. The following are the main steps to operate a hydraulic tube bender:

  • Set Up Your Bender: All manual benders are recommended to limit the pipe or pipe size that can be effectively bent. The limit can vary depending on the material of the tube and the cross-section and thickness of the tube. Your bender will have an adjustment dial that needs to be set based on the radius you need in the tube and the total number of degrees you need to bend. You may need to adjust the calculation according to the radius you want to reach to get the desired result. Another factor that you need to remember is whether you can use a vise. Most manual pipe benders can be fitted with a vise, and if you want to bend thicker-walled pipes, you must use this environment.
  • Mark Bend Directions & Reference Points: Since you may make multiple bends on a single test tube, you should mark your test tube with a longitudinal line for reference. The line should always stay in the direction opposite to the direction of bending to be achieved. The reference and measurement marks on the test tube will ensure that you get the results you need and can monitor your progress.

  • Align & Insert the Tube Into The Bender: You must swing one of the two bending arms up to insert the tube into the bending mold while ensuring that the reference mark is always visible. After inserting the tube, the latch mechanism can usually be used to lower the second arm to hold the tube in place while making minor adjustments.

  • Start the Bending Process: You can start the bending process by firmly holding the roller support arm and lowering it until the required degree mark is reached on the bending mold. You should note that most pipes tend to have a certain degree of rebound after bending. Copper pipes typically have lower strength compared with steel pipes. Make sure spring back is paid during this process.
