To bevel a tube means to reduce or to slim down the wall thickness of this tube at its edges. This needs to be done when the wall thickness is of more than 3 millimetres and allows therefore to prepare the assembly of the tubes/accessories.
Let us return to the question of the bevel, which will reduce the thickness of the tube in order to allow welding. Generally speaking, a tube with a wall thickness of more than 3 mm cannot be welded with only one layer in TIG welding.
Every country has its own designations for steels. The European standard EN10027 classifies four different categories of steels:
If you need a high quality weld, the preparation of the pipe is essential. Several steps have to be followed before welding and the preparation of the bevel is most important. A high quality bevel ensures a clean and perfect weld. There are two ways to prepare a bevel.
The research and development centre of AXXAIR has always addressed the research activities in order to provide you with an easy to use equipment, combined with high productivity standards and security levels. The quest of efficiency and perfection guides us every day.
How to align two tubes that have not been correctly cut? How to avoid imperfections?
In the food processing or pharmaceutical industry the use of < 3 mm wall stainless steel tube has an essential aspect: the orbital cutting. In order to do this, you have to take into account the relative fragility of these thin tube which need a meticulous care, for stability and fixation when you clamp them.
AXXAIR, founded in 1997 by Mr. Frédéric LEGRAND is specialized in orbital tube working machines. The beginning of the adventure became immediately international with the establishment of a solid worldwide distribution network.
Squaring your tubes can allow you to save money especially while working with microfittings.
Orbital cutting has perfect results in most cases. But sometimes it's not enough and you'll need to prepare your tubes before.
