What should the wall thickness be at the end of the tubing after deburring?

The wall thickness at the end of the tubing after deburring should be reduced but must not fall below the minimum specification. Deburring is a process that involves removing sharp edges or burrs created during cutting or machining. This process may inadvertently reduce the wall thickness at the ends of the tubing, which is acceptable as long as the remaining thickness meets the standards and specifications necessary for structural integrity and functionality.

Maintaining a wall thickness above the minimum specification is crucial because it ensures that the tubing can withstand the pressures and stresses it will experience during operation without failure. If the wall thickness is allowed to drop below the specified minimum, there could be serious risks such as leaks or ruptures, which could lead to safety hazards or equipment malfunction.

On the other hand, keeping the wall thickness unchanged is not practical, as deburring naturally alters the end profile of the tubing. Similarly, suggesting that the wall thickness should be increased from the original thickness or reduced by a set percentage would not consider the necessary structural requirements that must be adhered to, which emphasizes the importance of the minimum specification.
