Which piping material is recommended to be used in extra heavy duty sizes in ammonia refrigeration system construction?

Question 1 of 27070

Which piping material is recommended to be used in extra heavy duty sizes in ammonia refrigeration system construction?

🔍 Key Concepts

• Compatibility of ammonia with common piping metals • Corrosion and embrittlement issues with copper and copper alloys in ammonia systems • Why industrial refrigeration systems often specify particular steel grades and wall thickness (extra heavy duty)

💭 Think About

• First, think about which metals ammonia attacks or weakens over time—especially copper-based alloys. • Then, consider which material is commonly used for high‑pressure, industrial piping where strength and wall thickness (extra heavy) are important. • Ask yourself: in real‑world ship or plant ammonia systems, what material do you most often see specified in class/USCG/ABS drawings and manufacturer manuals?

✅ Before You Answer

• Eliminate any metals you know are not compatible with ammonia, particularly those forming harmful compounds. • Focus on the one material that is standard for high‑pressure, industrial piping and can be ordered in extra heavy wall sizes. • Verify which of the listed materials is specifically avoided in ammonia systems due to chemical reaction with ammonia.
