Which of the following is commonly used as a material for distribution pipes?

PVC, or polyvinyl chloride, is widely used as a material for distribution pipes due to its favorable properties. It is lightweight, resistant to corrosion and chemicals, and has good tensile strength, making it suitable for transporting water and other liquids. PVC pipes are also cost-effective and easy to install, allowing for efficient and economical underground construction.

In addition to its practical applications, PVC's smooth interior surface minimizes friction loss, which enhances flow efficiency. Its resistance to UV light and various environmental factors also ensures a long service life, making it a popular choice in both residential and industrial settings for water distribution systems and sewage management.
