Q: How are ductile iron pipes protected against internal corrosion?: Ductile iron pipes are protected against internal corrosion through a combination of various preventive measures. One of the primary methods is the application of a protective coating on the inner surface of the pipe. This coating acts as a barrier between the pipe and the transported fluid, preventing direct contact and minimizing the chances of corrosion. Another common method used is the application of a cement mortar lining. This lining further enhances the protective barrier, reducing the likelihood of corrosion even in aggressive environments.

Q: What are the different types of valves available for ductile iron pipe?: Ductile iron pipe offers a variety of valve options, each with its own unique purpose and function. Among the most commonly used valves are: 1. Gate Valves: These valves are designed to either fully open or fully close the fluid flow in the pipe. They feature a gate-like mechanism that permits or blocks the passage of fluid depending on the valve's position. 2. Butterfly Valves: Butterfly valves are quarter-turn valves that utilize a circular disc to control the flow. When open, the disc aligns parallel to the flow, resulting in minimal pressure drop. Conversely, when closed, the disc aligns perpendicular to the flow, effectively stopping the fluid. 3. Ball Valves: Ball valves consist of a spherical disc with a central hole, known as a ball. When the valve is open, the ball is positioned to allow fluid to pass through the hole. To close the valve, the ball is rotated to obstruct the flow. 4. Check Valves: Check valves are specifically designed to permit fluid flow in one direction only, preventing backflow. They incorporate a flap or disc that opens when the flow is in the correct direction and closes to halt the flow when reversal occurs. 5. Plug Valves: Plug valves feature a cylindrical or conical plug with a through-hole that can be rotated to regulate the flow. When open, the hole aligns with the pipe, enabling fluid to pass. Closing the valve positions the hole perpendicular to the pipe, blocking the flow. 6. Pressure Reducing Valves: These valves serve the purpose of controlling and reducing the pressure of fluid within the pipe. They employ a mechanism that adjusts the flow area to achieve pressure reduction. 7. Pressure Sustaining Valves: Pressure sustaining valves are utilized to maintain a specific pressure level within the pipe. They automatically adjust the flow area to sustain the desired pressure. 8. Air Release Valves: Air release valves are employed to eliminate trapped air within the pipe. They allow air to escape while preventing fluid leakage. These examples demonstrate the diverse range of valve options available for ductile iron pipe. The selection of a suitable valve depends on factors such as the application, flow requirements, and desired functionality.
