Polyethylene (PE) is a durable, flexible plastic material used in plumbing for various applications, including water supply, drainage, and irrigation. It is resistant to corrosion, chemicals, and environmental stress, making it suitable for both indoor and outdoor installations. PE pipes are available in different types, such as high-density polyethylene (HDPE) and cross-linked polyethylene (PEX), each designed for specific pressure ratings and temperature ranges. PE is commonly used in cold water lines, gas distribution, and underground piping due to its flexibility and ease of installation. Proper joining, such as fusion welding or mechanical fittings, ensures leak-proof connections and long-term performance.
