What is the primary benefit of using a sleeve for a pipe passing through concrete?

• A. It adds aesthetic appeal
• B. It helps to reduce thermal expansion
• C. It protects the pipe from damage
• D. It increases pipe durability

Answer: (C)

Using a sleeve for a pipe passing through concrete serves primarily to protect the pipe from damage. When pipes are encased in concrete, they can be subjected to various stresses, such as pressure from the surrounding material during curing, movements from thermal expansion or contraction, and other forces associated with the building structure. A sleeve creates a barrier between the pipe and the surrounding concrete, allowing for some movement without risking stress or damage to the pipe itself. This protective measure is essential in maintaining the integrity of the plumbing system and preventing leaks or failures that could result from the concrete's rigid properties. Though options like thermal expansion and durability may also have relevance in certain contexts, the definitive advantage of a sleeve in this scenario is its role in safeguarding the pipe against potential physical harm caused by the concrete.
