Pipe bending is the process of modifying pipes so that they can achieve a desired angle or direction. These modifications are permanent and mean that the pipes can be used in a number of different applications.
There are a number of options when it comes to bending machines. Euromac bending machines are regarded as some of the best around. There are several suppliers who offer these machines (and others) – many of which have online resources such as the examples seen here: www.cotswold-machinery-sales.co.uk/euromac-bending-machines/horizontal-bending-machines/.
There are four main pipe bending methods: compression bending, roll bending, rotary draw bending and mandrel tube bending.
Compression Bending
This method relies on a pushing force to change the shape of the pipe material. This method is best suited to pipes that only need simple bending formations. However, it is not able to achieve complex bending formations.
Roll Bending
This method utilises a series of rollers to shape the pipes as desired. Different forces are applied on each roller. There are several different bending processes. There are roll bending machines that feature a number of continuously moving components. Roll bending is versatile and precise.
Rotary Draw Bending
The main downsides are that this technique needs a significant amount of tooling, and the initial setup can be time-consuming.
Mandrel Tube Bending
This method utilises a mandrel or rod which is inserted into the tube as it is being formed. Part of this is flexible, allowing the directional bend on the material to be achieved. This technique offers high precision, maintains the pipe integrity and allows for better flow within the pipe.
What systems might require these types of pipes?
Systems that may need pipes like this include HVAC systems, fluid transfer systems, pneumatic conveying systems and some plumbing systems.
