Sample interview questions: How do you ensure proper insulation and protection of hydronic system piping in seismic zones?
Sample answer:
Proper Insulation and Protection of Hydronic System Piping in Seismic Zones
Ensuring Seismic Resilience:
- Use Flexible Piping: Install flexible piping materials such as corrugated stainless steel or PEX tubing to absorb seismic vibrations and prevent damage to joints and connections.
- Provide Anchoring: Secure piping at regular intervals with seismic-rated supports, clamps, and hangers to prevent excessive movement and potential ruptures.
- Isolators and Sway Braces: Install seismic isolators beneath piping to reduce vibrations and sway braces to prevent lateral movement.
Insulation and Protection:
- Insulate Piping: Cover piping with thermal insulation to maintain water temperature, reduce heat loss, and prevent condensation. Use materials that are flame-retardant and moisture-resistant.
- Use Protection Jackets: Protect piping from external damage by installing protective jackets made of durable materials such as PVC or metal.
