A Bourdon tube-type steam pressure gage is fitted with a siphon loop to prevent damage from the direct effects of __________.

🔍 Key Concepts

• Bourdon tube pressure gage operation and what actually causes damage inside the tube • Purpose of a siphon (pigtail) loop in steam service piping • Difference between protecting against temperature effects vs pressure effects

💭 Think About

• Ask yourself: Is the Bourdon tube more vulnerable to sudden changes in pressure or to very high temperature from live steam? • Think about what collects in the loop of a siphon: is it normally filled with steam or with water, and how does that protect the gauge? • Which option describes the medium that the siphon is trying to keep away from direct contact with the gauge element?

✅ Before You Answer

• Identify what fluid (steam or condensate) is supposed to stay in the siphon loop under normal conditions — this is critical. • Decide whether the main danger to the Bourdon tube is excessive heat or excessive pressure in normal steam service. • Rule out any option that doesn’t match the actual function of a small water-filled loop in front of a steam gauge.
