The mandrel bending process is used to prevent the internal structure of the pipe from deteriorating during bending. This method performs the plastering process by staying inside and in the center of the pipe during the bending phase. In this way, spreading of the pipe is prevented and its form is preserved. It is ideal for bending operations in narrow radii and is preferred in situations requiring high precision. SBFM Makine's machines with 3 roll plate hydraulic system and 4 roll plate hydraulic system are ideal for performing mandrel bending operations.

What is Pipe Bending?

The pipe bending process allows the pipe to be bending to a certain angle. This process makes it possible to bend pipes into a specific shape and use them in various industrial and commercial applications. Pipe bending can be applied for pipes of different diameters and materials and is generally used in many sectors such as construction, automotive and aerospace.

How Many Times The Pipe Diameter Should The Diameter To Be Bent Be İn Pipe Bending?

In pipe bending processes, the curling diameter is determined according to the diameter of the pipe. As a general rule, the diameter of the pipe to be bending should be at least 3 times the pipe diameter. This ratio prevents distortion and deformation of the pipe structure during bending. For narrow bending diameters, the mandrel bending method is used.

What is a Hydraulic Pipe Bending Machine?

Hydraulic pipe bending machines are machines designed to bend pipes using hydraulic power. These machines facilitate pipe bending processes by providing high precision and repeatability. Hydraulic pipe bending machines have adjustable features for pipes of different diameters and materials and are often used in industrial production processes.

How to Bending Hydraulic Pipe?

The hydraulic pipe bending process is carried out in the following steps:

1. Preparation: The size and angle at which the pipe needs to be bending is determined. The pipe is placed in the bending machine.

2. Adjustment: The hydraulic bending machine is adjusted according to the bending angle and radius.

3. Bending: The hydraulic system completes the process by bending the pipe at the specified angle and radius.

4. Control: The bending pipe is subjected to size and quality control. Corrections are made when necessary.
