1. Safety Precautions: As with any metalworking process, take safety precautions while bending stainless steel pipes. Wear eye protection, work gloves, and appropriate work shoes.

2. Pipe Selection: Choose the right stainless steel pipe for the job. The thickness and diameter of the pipe are crucial factors for the bending process.

3. Prepare Pipe Ends: Cut both ends of the pipe to be straight and sharp. There should be no rough or irregular edges inside the pipe.

4. Select Bending Machine: Use a suitable bending machine or drill press for bending stainless steel pipes. These machines allow you to bend the pipes precisely.

5. Prepare Pipe End: Place one end of the pipe into the bending machine, ensuring it sits properly.

6. Bending Process: Gently feed the pipe into the bending machine. Bend the pipe to the desired angle. Do not progress too quickly during the bending process, as it may risk cracking the pipe. Depending on the need, you may make several passes.

7. Finishing Steps: After bending the pipe to the desired shape, cut the end cleanly and, if necessary, clean it up. Smooth out any rough edges.

8. Quality Control: Visually inspect the bent pipe for any cracks, breaks, or other damage. 

By following these steps, you can safely bend stainless steel pipes. However, such processes require experience, and for larger or complex bending tasks, you may need the assistance of a skilled worker or engineer. Additionally, it's essential to carefully follow the user manuals of the bending machines when working with them.
