What precaution should be observed during the deburring process?

During the deburring process, it's crucial to ensure that the wall thickness at the end of the tubing is not reduced. This is because excessive deburring can compromise the structural integrity of the tubing by thinning its walls. Maintaining the original wall thickness is vital for ensuring that the tubing can handle the pressures and stresses it will encounter in service. A tubing wall that is too thin may lead to failure under pressure, leaks, or compromised flow characteristics.

The other considerations in this context emphasize practical aspects of the deburring process that may not enhance safety or performance effectively. Using power tools for deburring can increase the risk of overworking the material, which could potentially cause damage. Increasing tube diameter does not relate directly to the deburring process; instead, it pertains to designing systems for better flow, which is a different aspect of fluid mechanics. Lastly, maintaining an excess of tubing length isn't directly relevant to deburring and typically pertains more to accommodating fitting tolerances and ensuring sufficient material for connection purposes.
