Core pulling and bending process of stainless steel circular pipes

Core pulling and bending process of stainless steel circular pipes can be done using the following steps:

1. Prepare the pipe by cutting it to the desired length and removing any burrs or sharp edges with a deburring tool.

2. Choose the appropriate mandrel size for the pipe diameter and insert it into the pipe.

3. Secure the mandrel and pipe in a bending machine or press, making sure the mandrel is centered and the pipe is clamped tightly.

4. Use the bending machine or press to bend the pipe to the desired angle. The mandrel will prevent the pipe from collapsing or flattening during the bending process.

5. Once the pipe has been bent, remove the mandrel by pulling it out of the pipe. This process is known as core pulling.

6. Inspect the bent pipe to ensure it meets the required specifications and is free of defects or cracks.

7. Repeat the process for any additional pipes that need to be bent.

Note: It’s crucial to use the appropriate mandrel size and bending machine or press for the pipe diameter to avoid damaging the pipe or mandrel. Also, follow all safety precautions when using bending machines or presses, such as wearing protective gear and ensuring the machine is properly calibrated.
