What is the main purpose of cement-lining a metallic pipe?

• A. Protect the pipe from corrosion
• B. Structural support
• C. Prevent slime growth
• D. Prevent scaling

Answer: (A)

The primary purpose of cement-lining a metallic pipe is to protect the pipe from corrosion. Over time, metallic pipes can degrade due to environmental factors and the nature of the fluids they transport, which can lead to rust, pitting, and ultimately a failure of the pipe material. Cement lining provides a barrier that shields the metal from direct exposure to corrosive elements, including water and chemical substances. This protective layer can significantly extend the lifespan of the pipe and minimize maintenance costs associated with corrosion-related issues. The other options, while they may address important aspects of pipe management, are not the primary goals of cement lining. This process specifically targets corrosion prevention, making it a critical consideration for ensuring the longevity and reliability of water distribution systems.
