Why is the distance between bends important?

The tubing work our team performs helps clients from a wide array of industries. With our tube swaging skills, we can create all kinds of products. Examples include heating components, furniture, and railings. We’re only scratching the surface here however; whatever you need, we are confident we can provide it.

Designing tubular components is rarely a simple process because you need to consider a myriad of factors. The trouble is that not everyone knows what they are. Fortunately, we are here to help.

How much distance between bends?

One of the most vital elements is the distance between bends. This is the quantity of straight material between bends that you can use for gripping. Expanding the grip length reduces the chances of the tube slipping in the bending operation. It also means you can bend with lower forces. As a result, this increases the machine life and decreases the frequency of replacement.

Clamping lengths

The bending tension increases as the bends become more severe. At the same time, the distance between bonds grows. For basic tube bending instruments, the minimum clamping length is as follows:

If the severity of the bend is < 2, 4 x OD is the minimum distance between bonds If the severity of the bend is > 2, 3 x OD is the minimum distance between bonds

The bend may not fall within these though. If this happens, don’t worry because there are options. However, a lot of them require to you sacrifice some quality. One example would be investing in extra features like a multistack bender. Remember to be careful when considering what to do.

At Multiform Tubes, we can obtain excellent surface finishes by using tube swaging. On the exterior, there will be smooth, circular finishes regardless of what the interior shape is. In addition, we offer short cycle times and no material loss.
