Final answer:
Sleeves are provided to protect all piping passing through walls. The correct answer is 1) Interior and exterior. Sleeves are installed to create a smooth penetration through the wall, maintaining the integrity of the structure and preventing any leakage. Option 1.
Step-by-step explanation:
According to engineering standards, sleeves are provided to protect all piping passing through walls.
The correct answer to the question is 1) Interior and exterior. Sleeves are used to provide a protective barrier around pipes that pass through both interior and exterior walls, ensuring that the pipes are shielded and sealed from potential damage or leaks.
For example, in a building, pipes for plumbing, HVAC systems, or electrical conduits may pass through walls. To avoid cracks, gaps, or structural issues caused by pipe movement, sleeves are installed to create a smooth penetration through the wall, maintaining the integrity of the structure and preventing any leakage.
Sleeves are provided to protect piping that penetrates through walls. According to building codes and construction standards, these sleeves are required for both interior and exterior walls. The correct answer to the question is 1) Interior and exterior. Sleeves help to prevent pipe damage from wall contact, allow for easier installation and future maintenance, and provide a barrier to fire and sound transmission. In some cases, they are also used to accommodate thermal expansion and contraction of the piping material.
