Beveling is the process in which we form an angle between the edge of a pipe and a plane perpendicular to the surface to a certain degree, most commonly used to prepare the ends of pipes for welding. Beveling can also be used for deburring the cut tends for safety and aesthetic reasons. Beveling can be applied to the face of any size or diameter of a pipe.

What is the pipeline beveled end and why it is used?

In fact, it is processed prior to the welding of two pieces of line pipes, an angle formed at the edge of the end of the pipe by a beveling machine. The beveling of pipe or tubing is most commonly used to prepare the ends for welding. It can also be used for deburring the cut ends for safety and aesthetic reasons.

Subtract the pipe’s wall thickness from the pipe’s outside diameter. For example, if you had a pipe with a diameter of six inches and a wall thickness of two inches, you would subtract two from six to get four.

The reason why one pipe is beveled?

The beveling of pipe or tubing is most commonly used to prepare the ends for welding. It can also be used for deburring the cut ends for safety and aesthetic reasons.

Common types of beveled ends

Beveling ends can be made from various angles, achieving a better welding seam. Common beveled ends for butt joints are I—Type butt joint, single—V beveled end, double—V beveled end, and single U—beveled end.

The groove form of pipes, pressure vessels, and steel structures shall be processed in accordance with the design drawings. If there is no stipulation, the form and size of the groove should be selected according to the principles of ensuring the welding quality and filling less metal, improving labor conditions, facilitating operation, reducing welding profit and deformation, and adapting to the requirements of flaw detection. In practice, the commonly used groove has four forms, such as V type, U type, double V type, and X type. The processing method is divided into oxygen, acetylene flame cutting, carbon arc gouging, turning, manual file, etc.

V type is suitable for all kinds of pressure pipe, pressure vessels,s and thin parts bearing structures; U type is suitable for medium and thick wall soda pipe; Double V type is suitable for medium and thick wall soda pipe;

Points for attention when processing beveling by machine：

1. Before processing beveling, it is necessary to repair the uneven and inclined plane.

2, Beveling inside and outside the wall 15-20mm to remove rust, oil, and other debris, exposing metal luster.

3. When processing beveling, the feed should be slow. The amount of the knife is 0.2-0.3mm each time. Direct contact with the pipe is strictly prohibited.

4. The knife Angle should be consistent with the beveling Angle, and the beveling surface should be made evenly and in place.

5. When processing the pipe with the mouth up, it is necessary to put debris into the pipe.
