Why should piping carrying catalyst, flue gas, or slurry be subject to careful scrutiny?

• A. Due to potential leaks in the system
• B. Because they are not hazardous materials
• C. Due to the highly erosive or corrosive nature of these substances
• D. Because they require less maintenance

Answer: (C)

Piping systems that transport catalyst, flue gas, or slurry require careful scrutiny primarily due to the highly erosive or corrosive nature of these substances. These materials can interact detrimentally with the piping material, leading to accelerated wear and degradation. For example, catalysts may contain aggressive chemicals that can corrode metal surfaces, while slurries, which are often a mix of solids and liquids, can create erosion through abrasion as particles scrape against the pipe walls during flow. Additionally, the corrosive properties of flue gases can lead to the formation of acids that attack metal piping. Excessive corrosion or erosion can compromise the integrity of the piping system, potentially leading to leaks or failures, which can have significant operational and safety implications. Therefore, ensuring that these piping systems are closely inspected and maintained is crucial to prevent accidents and maintain system reliability.
