Question 1 of 27070

Pure anhydrous ammonia is considered noncorrosive to what metal or metals?

🔍 Key Concepts

• Material compatibility of anhydrous ammonia with different metals • Typical piping and tank materials used for anhydrous ammonia cargo systems • Why copper and copper alloys behave differently in ammonia service than ferrous metals

💭 Think About

• Think about which metals are most commonly used for permanent storage tanks and pipelines that carry anhydrous ammonia in industry and on tank vessels. • Consider what happens when ammonia contacts copper or copper alloys over time—does it help prevent corrosion, have no effect, or can it cause stress and cracking? • Ask yourself: if you were designing an ammonia cargo system, which metals would you definitely avoid because of known compatibility problems?

✅ Before You Answer

• Verify which metals are standard and approved for anhydrous ammonia cargo piping and tanks in reference materials or regulations. • Double-check whether copper-bearing metals are recommended, allowed with restrictions, or specifically prohibited in ammonia service. • Confirm whether both iron and steel fall into the same compatibility category with anhydrous ammonia for being considered noncorrosive.
