What kind of pipe rupture occurs when the pipe has completely separated?

• A. Partial rupture
• B. Burst rupture
• C. Cracked rupture
• D. Severed rupture

Answer: (D)

This item tests how pipe failure is described by the extent of separation. When a pipe has completely separated, the correct term is severed rupture. That means the pipe wall has given way all the way through and the pipe breaks into two pieces, no longer connected. This has serious damage-control implications because you’ll have two exposed ends that can leak and require isolation and repair.

The other terms describe different conditions: a partial rupture means only part of the wall has failed while the pipe remains one piece; a burst rupture refers to a failure from internal pressure that can blow out a section but doesn’t necessarily imply complete separation; a cracked rupture indicates cracks without full separation.
