Drainage and sewer pipes are designed to efficiently transport wastewater and sewage from residential, commercial, and industrial facilities. These pipes must withstand continuous flow, external loads, and corrosive waste materials. Smooth internal surfaces help prevent blockages and ensure efficient discharge. Drainage pipes are commonly used in underground installations and municipal networks. Durability and leak resistance are key to preventing environmental contamination. These pipes support hygienic waste management systems. Proper installation ensures long-term performance with minimal maintenance.
