When do you use cast iron piping?

• A. When temperature and pressure are not critical
• B. When temperature and pressure are not high
• C. When corrosion resistance is required
• D. When vacuum conditions exist

Answer: (A)

Cast iron piping is chosen for services where temperature and pressure are not critical. It’s well-suited to low-pressure, modest-temperature applications such as drainage and sewer lines, where the conditions don’t demand high-temperature resilience or tight pressure containment. Cast iron is economical and strong in compression, but it’s brittle and does not handle high heat, high pressure, vacuum conditions, or aggressively corrosive fluids as well as some other materials. So the best-fit scenario is when the service conditions aren’t demanding in temperature or pressure.
