Final answer:
The burred ends of pipe and tubing should be cut off to remove the rough or uneven edges.
Step-by-step explanation:
When dealing with burred ends of pipe and tubing, the correct action is to cut off the burrs.
Burrs are rough or uneven edges that can occur after cutting or machining operations. They can interfere with fittings, cause leaks, or affect the flow of fluid or gas through the pipe or tubing.
The burrs should be carefully removed by cutting them off using appropriate tools like a pipe cutter or a deburring tool.
