Question 1 of 27070

Coast Guard Regulations (46 CFR Part 56) permit copper pipe to be used for steam service subjected to a maximum pressure and temperature of __________.

🔍 Key Concepts

• 46 CFR Part 56 piping material limitations for copper pipe • How pressure and temperature limits are paired for specific materials in steam service • Difference between allowable working pressure and temperature ratings for nonferrous piping in power piping systems

💭 Think About

• First, compare which answer choices pair the higher pressure with the higher temperature, and think about whether that is usually allowed for nonferrous metals like copper in steam service. • Recall that copper has lower strength at elevated temperatures; which combinations seem more conservative and realistic for steam rather than for low‑temperature services? • Ask yourself: for safety, would regulations more likely restrict copper by pressure, by temperature, or by both in steam conditions?

✅ Before You Answer

• Check 46 CFR Part 56 tables for copper pipe specifically in steam service (not just general services). • Verify which maximum working pressure is allowed at the highest listed temperature for copper in steam service. • Confirm you are not mixing limits for water or air systems with those for steam systems; the steam limits are usually more restrictive.
