Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the key chemical classes?Organic inhibitors (amines, imidazolines, quaternary ammonium salts) and inorganic inhibitors
2. What is the operational stages of use?Drilling fluids, production tubing, flowlines, pipelines, storage tanks
3. What are corrosion inhibitors and why do they help oil pipes?Corrosion inhibitors are special chemicals that stop metal from rusting. They create a protective film or block the reactions that cause corrosion, keeping oil pipes safe.
4. How do anodic and cathodic inhibitors protect metal?Anodic inhibitors make a film on the metal to block oxidation. Cathodic inhibitors either speed up or block the reduction reactions, slowing the overall corrosion.

Anodic Polarization: The process of increasing the potential of the anode, slowing down metal oxidation and corrosion.
Cathodic Polarization: The process of decreasing the potential of the cathode, slowing down reduction reactions and corrosion.
Asset Integrity: Ensuring that industrial equipment and infrastructure remain safe and functional throughout its operational life.
