What is the purpose of deburring a tube after cutting?

Deburring a tube after cutting serves primarily to remove sharp edges that can develop during the cutting process. When a tube is cut, the edges often become jagged or sharp, which can pose a safety hazard to anyone handling the tube. Sharp edges can also lead to difficulties when connecting fittings, increasing the risk of improper sealing or connection failure. By deburring the edges, you not only improve safety but also facilitate a better fit between the tube and fittings, ensuring a more effective and secure connection in fluid systems.

While ensuring proper fitting, enhancing appearance, and polishing the surface may be secondary benefits, the main intent of the deburring process is to eliminate those potentially dangerous sharp edges. This crucial step in the preparation of fluid lines and fittings helps maintain overall integrity and reliability in fluid transport systems.
