  2. Cathodic protection - Wikipedia

    en.wikipedia.org/wiki/Cathodic_protection

    For pipelines, anodes are arranged in groundbeds either distributed or in a deep vertical hole depending on several design and field condition factors including current distribution requirements. Cathodic protection transformer-rectifier units are often custom manufactured and equipped with a variety of features, including remote monitoring and ...

  3. Zinc flake coating - Wikipedia

    en.wikipedia.org/wiki/Zinc_flake_coating

    Zinc flake coatings create what is known as cathodic protection: the less noble zinc 'sacrifices' itself in order to protect the underlying metal. Steel can be protected in this way. The coating thickness is often between 5 μm and 15 μm, with thicker layers also possible where there are special requirements.

    Both the legacy NACE and SSPC organizations were ANSI-accredited standards developers, which AMPP plans to continue.The merged standards program includes 25 standing standards committees that develop technical standards for industries including cathodic protection, coatings, defense, highways and bridges, rail, maritime, oil and gas, power and utilities, research and testing, tanks and ...

  5. Corrosion engineering - Wikipedia

    en.wikipedia.org/wiki/Corrosion_engineering

    Corrosion prevention measures, including Cathodic protection, designing to prevent corrosion and coating of structures fall within the regime of corrosion engineering. However, corrosion science and engineering go hand-in-hand and they cannot be separated: it is a permanent marriage to produce new and better methods of protection from time to time.

  6. Galvanic anode - Wikipedia

    en.wikipedia.org/wiki/Galvanic_anode

    A galvanic anode, or sacrificial anode, is the main component of a galvanic cathodic protection system used to protect buried or submerged metal structures from corrosion. They are made from a metal alloy with a more "active" voltage (more negative reduction potential / more positive oxidation potential ) than the metal of the structure.

  7. Copper–copper (II) sulfate electrode - Wikipedia

    It is used for measuring electrode potential and is the most commonly used reference electrode for testing cathodic protection corrosion control systems. [2] The corresponding equation can be presented as follow: Cu 2+ + 2e − → Cu 0 (metal)

  8. Stress corrosion cracking - Wikipedia

    en.wikipedia.org/wiki/Stress_corrosion_cracking

    Cathodic Protection: Cathodic protection is a technique used to protect metals from corrosion by applying a small electrical current to the metal surface. This technique can also help prevent SCC by reducing the corrosion potential of the metal. [7] Environmental Controls: Controlling the environment around the metal can help prevent SCC.

  9. DCVG - Wikipedia

    en.wikipedia.org/wiki/DCVG

    DCVG (direct current voltage gradient) is a survey technique used for assessing the effectiveness of corrosion protection on buried steel structures. [1] In particular, oil and natural gas pipelines are routinely monitored using this technique to help locate coating faults and highlight deficiencies in their cathodic protection (CP) strategies.
