Sample interview questions: Are you knowledgeable about gas system corrosion prevention methods and materials?
Sample answer:
-
Galvanization: A common and effective method of corrosion prevention for gas systems. Zinc is applied to the surface of steel or iron pipes and fittings, forming a protective coating that prevents corrosion.
-
Cathodic Protection: This method involves connecting a sacrificial metal to the gas system. The sacrificial metal corrodes instead of the system’s components, extending their lifespan.
-
Protective Coatings: Epoxy, polyurethane, and other protective coatings can be applied to the exterior of gas pipes and fittings to prevent exposure to corrosive elements.
-
Stainless Steel: Using stainless steel pipes and fittings eliminates the risk of corrosion due to its inherent resistance to rust and oxidation.
-
Corrosion-Resistant Alloys: Alloys such as copper-nickel and Monel are highly resistant to corrosion and can be used in gas systems exposed to harsh environments.
