What type of plastic pipe is approved for underground installation?

• A. Polyvinyl chloride (PVC)
• B. Polypropylene
• C. Polyethylene
• D. ABS (Acrylonitrile Butadiene Styrene)

Answer: (C)

Polyethylene is the correct type of plastic pipe that is approved for underground installation. This material is favored for its flexibility, resistance to corrosion, and ability to withstand a variety of environmental conditions. Polyethylene pipes are particularly suitable for underground applications, such as water service lines and gas distribution, due to their strength and durability. They can also handle ground movements and are less likely to crack or break compared to other materials. In addition, polyethylene has a smooth interior surface which reduces friction loss, making it efficient for fluid transport. Its performance under different soil conditions and temperate variations further establishes its reliability in underground settings. This is why polyethylene is widely utilized and recognized as compliant with industry standards for underground installations.
