The main difference between elbow and carbon steel elbow is the material, which contains chemical components that maintain the surface of the elbow for a long time without rusting or corroding.

In piping systems, elbows are fittings used to change the direction of the pipeline. Commonly, there are three types based on angles: 45°, 90°, and 180°. Additionally, other non-standard angle elbows, such as 60°, are included according to engineering requirements.
