Stainless steel is one of the most common materials for making pipes and tubes for a wide variety of applications. These tubes go through a number of processes to make them usable, one of which is tube bending.

Tube bending sounds like a simple technique, but there is a lot more to it. For any application, bending requires taking care of factors such as bend angle and bend radius so the tube fits the requirement perfectly.

Therefore, this article will discuss how to bend stainless steel tubing taking care of all the factors that matter.

What are the Different Ways to Bend Stainless Steel Pipes and Tubes?

There are many methods to bend stainless steel tubing. Some of these methods are:

Mandrel Bending

Mandrel bending is one of the most common types of bending methods. In this type of bending, a solid mandrel is inserted inside the tube, and pressure is applied to bend the tube. The purpose of the mandrel is to ensure the tube does not collapse on the application of pressure.

Three Roll Bending

Roll bending is also known as angle bending. In this type of bending, three rollers are placed consecutively to one another. The tube passes through these rollers, creating the required bend radius. The rollers can be placed in a horizontal or vertical position. Roll bending is used for stainless steel tubing when manufacturers require spiral bends.

Draw Bending

Draw bending is one of the simplest forms of tube bending machines. In this bending process, a tube is held stationary by a clamp die while a pressure die moves the tube to achieve the required bend angle. This bending is done without a mandrel. The bend die is placed to provide the circularity of the bend.

Compression Bending

In compression bending, the tube is held in position by a clamp die. Then it is bent around a stationary bend die while a compression die applies pressure on the tube. This type of bending method is used when symmetrical bends are required on the tube. The accuracy and bend quality achieved by this method is not very good.

What to Look for When Buying a Stainless Steel Tubing Bender?

When you are considering buying stainless steel tubing benders, there are certain factors you should consider. These factors are:

Budget

First things first, outline the price that you can pay for a stainless steel tubing bender. A higher price limit will allow you to get hydraulic benders that require little to no physical effort. If the budget is strict, you will have to settle with a mechanical tube bender which has a cheaper price. You can find a good quality one in any price range.

Bend Angle:

Every tube bender has a limitation on how much bending angle it is capable of. A higher range of bend angles greatly increases the possible application of the tube bender. Most tube benders have a maximum bend angle compatibility of 180 degrees. RogeuFab’s metal tubing benders can go very far beyond that.

Springback

When choosing a tube bender, it is important to go with a machine that has measures to eliminate springback. Springback is common in metal tubing, and can often cause the deformation of the bend, destruction of the tube, or even injury to the operator in some cases.

Material Thickness

Material thickness is another important factor that can vary among different tubing benders. As in the case of bend angle, going with a machine that can support a higher thickness increases the applicability of the product.

One Shot Angle

All tubing benders have a maximum bend angle they can achieve in one go. The higher this angle, the lesser effort is required to create any particular bend. It speeds up production speed and ease of bending significantly.

What are the Benefits of RogueFab Tube Benders for Stainless Steel Bending?

RogueFab makes some of the most high-quality tubing benders in the industry. Whether bending steel or aluminum, professionals choose these machines for a variety of reasons such as:

  • RogueFab benders come with support for a hydraulic conversion kit. This kit can transform any mechanical bender into a hydraulic bender, providing vast scalability in the future. This is a very useful feature if you are initially searching for a lower-price bender.
  • All tube benders in the RogueFab catalog have a bending capability of more than 180 degrees. The one-shot bending angle is 94 degrees, which is more than what any other alternatives offer.
  • These benders are very versatile, with the capability to create simple bends and complex bends such as the S bend. They can bend not only steel, but also brass, aluminum, copper, and even titanium tubes (limited wall thickness).
  • They support a maximum thickness of 2 1/4″, which provides the possibility to manufacture turbo manifolds in-house. This lowers the manufacturing price significantly and speeds up the manufacturing process.

Frequently Asked Questions (FAQs)

Here are the answers to some common questions about stainless steel tubing benders:

How hard is it to bend stainless steel tubes?

Without the proper equipment, stainless steel tubes can be impossible to bend, or might deform while bending. However, with high-quality benders such as the RogueFab, bending steel tubes is easy and possible with little physical effort.
