Answers:

1. Cement lined ductile iron pipe fittings are commonly used in water and wastewater systems because they offer superior durability and corrosion resistance. This makes them an ideal choice for applications where water quality and long-term performance are critical.2. The advantages of cement lined ductile iron pipe fittings over other materials include: - Corrosion resistance: The cement lining acts as a protective barrier to prevent the metal from coming into contact with corrosive elements in the water. - Abrasion resistance: The cement lining also provides a smooth interior surface, reducing the risk of abrasion and minimizing friction loss in the pipeline. - Longevity: Ductile iron is a durable material that can withstand the high pressures and stresses commonly found in water distribution systems. - Cost-effectiveness: While initial costs may be higher than other materials, the long service life and low maintenance requirements of cement lined ductile iron pipe fittings make them a cost-effective choice in the long run.3. The cement lining in ductile iron pipe fittings works by forming a protective layer on the interior surface of the pipe. This layer acts as a barrier between the corrosive water and the metal, preventing damage and extending the lifespan of the fittings. The lining is typically applied through a centrifugal spinning process, ensuring a consistent and uniform coating throughout the pipe. This coating not only protects the pipe from corrosion, but also helps to maintain smooth water flow and reduce the buildup of sediment and debris inside the system.
