The pipe beveling process is aimed to shape the edges of pipes into a predetermined angle. In many cases, beveling is performed as a part of work piece preparation for welding. 37.5⁰ is considered as a standard bevel angle for welding purposes. Apart from welding, beveling is also performed to debur the cut edges. The beveling machines are also widely used to produce J-bevels.

Features:

When you move out to purchase pipe bevellers, check out for the following features:

• The device purchased should accommodate the sizes of pipes to be beveled.
• The cutter head should be adjustable and supplied with gauges for accurate machining.
• Prefer carbide tips for cutting purposes.
• Interchangeable grips can increase the range of application.
• For accurate speed control, electrical systems should be used to vary speeds.
• If the machine can enclose the cutting area completely, it ensures safety in the workplace.

Procedure of beveling:

• If the device doesn’t secure the pipe, use a towel to wrap the interface area. Using angle knob, adjust it to the desired position.
• Before initiating the machining process, ensure to calculate the angle with respect to the length of the pipe.
• Measure the length of the bevel. Remember that this length determines the material removed in the process.
• Using the device, carryout beveling process. If the rollers are absent in the workplace, you can opt for a vice.
• After completion of the machining process, inspect the quality of the process by checking out the angle made at various points.

Field of application:

• In the pipe welding applications, external pipe beveling machines are used for bevel of pipe ends.
• Operations like beveling and facing are performed on the pipe edges with the help of this device. Even a heavy walled pipe can be processed accurately in the least time possible.
• Depending upon the application, special tool holders have to be employed to support these devices.
• In general, they are designed and manufactured to be lighter in weight. Metals like aluminum are used in their construction. This makes the operator feel at ease and can be used in any complex work area.
• By employing special tool bits in the process of facing and beveling, we can produce pipes, headers and tubes economically.
• They are also extensively used in high pressure boilers to remove the membranes of boilers panel, repairing boiler tube panel and others.

Safety precautions:

• You could have inferred that, this method makes use of tools which can cause significant damage when handled by a novice person. The operation has to be carried out by the trained personnel.
• There are chances that the operator can be injured. Make use of the safety equipments like goggles, shoes and gloves.
• Understand the metallurgy of the pipe. A few metals emit toxic fumes when exposed to high temperature. The work area has to be prepared to face such challenges.

Have a close look at the specifications of the device before purchasing. This can let you to decide the perfect one for your requirement.
