Question 1 of 27070

According to 46 CFR, which of the following statements is true concerning main boiler safety valve escape piping?

🔍 Key Concepts

• 46 CFR requirements for main boiler safety valve escape piping • Purpose of safety valve escape piping: protect the valve body and safely discharge to atmosphere or drain tank • Differences between support/installation requirements and routing (vertical/horizontal) requirements

💭 Think About

• Look at each option and ask: Does 46 CFR clearly require or prohibit this in the exact way it is worded? • Consider what could damage or affect the proper operation of a safety valve—would thermal expansion, weight of piping, or direction of piping matter most? • Think about why the regulations care about stress on the safety valve body and how that might be addressed in piping design.

✅ Before You Answer

• Verify in 46 CFR whether expansion joints or flexible connections are explicitly prohibited or allowed in safety valve escape piping. • Check if 46 CFR actually requires the piping to be led as near vertical as possible to the atmospheric drain tank, or if the rule is stated more generally. • Confirm whether there is a specific requirement that the escape piping be supported and installed so that no stress is transmitted to the valve body.
