Sample interview questions: What measures do you take to ensure that piping systems are designed to minimize the risk of fluid contamination and pollution?
Sample answer:
- Material Selection: Choosing corrosion-resistant materials that are compatible with the fluids being transported and external environmental conditions helps prevent contamination.
- Surface Treatment: Employing surface treatments such as passivation, electroplating, or coating protects piping surfaces from corrosion and minimizes the release of contaminants.
- Proper Piping Layout: Ensuring proper drainage, avoiding dead legs, and providing sufficient slopes for self-draining reduces the risk of fluid stagnation and contamination buildup.
- Valves and Fittings: Selecting valves and fittings with leak-tight closures, corrosion-resistant materials, and appropriate surface finishes minimizes potential leakage and contamination.
- Welding and Fabrication: Implementing precise welding techniques, using qualified welders, and adhering to strict quality control measures ensures the integrity and cleanliness of welded joints.
- Flushing and Cleaning: Before commissioning, thoroughly flushing and c… Read full answer
