Tubes can buckle when bent

Everyone needs a reliable service if they require tube manipulation to adapt tubing. We happen to be a company that provides this. You may not believe that your industry is one that will need such services. However, it would surprise you to know just how versatile they are. We can create products for a range of uses.


When you bend a tube there is potential for different issues. You need to look closely at each piece of tubing to determine what they are. You may see deformation, distortion, or collapse of the material.

Because bending problems all have their own causes, they each demand unique solutions. It is even possible to come across a myriad of complications at once in a single bend. To keep things simple, we are going to focus on buckling.

Why does a tube buckle?

A buckled bend as some call it happens because the substance you are bending is especially hard. When bent, these materials may not compress correctly on the bend’s inner radius. This can result in deformations.

What can you do about it?

Like with most bend troubles, examining your tools should be the initial step. You need to set your tooling appropriately for a bend to succeed. Even if you think everything is in order, it would be worth your time to do some checks.

Plug mandrels

Normally, when you organise your tooling properly, you can resolve a buckled bend by using a plug mandrel. You can use one to create decent quality bends in tubing that is 3/8î diameter and smaller. An exception to this would be a centre line radius lower than 2 x tube O.D. Another would be thin wall tubing. There are also restrictions in place for tubes that exceed 3/8î diameter.
