Cathodic protection (CP; / k æ ˈ θ ɒ d ɪ k / ⓘ) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. [1] A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes ...
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 ...
Within a cathodic protection system there are a multitude of connection requirements for anode cables, measuring posts etc., being extremely versatile, the pin brazing system is ideally suited to this. Attachments can be made vertically, horizontally or even overhead.
The company's business activities include engineering, construction, safety, turnaround and maintenance services, manufacturing, distribution, cured-in-place pipe (CIPP), installation, coating and insulation, cathodic protection, research and development and licensing.
Damage to the pipeline coating can result in the steel being exposed to the soil or water possibly causing localised corrosion. If the pipeline is buried, cathodic protection is used to minimise corrosion by maintaining the steel at a negative potential with respect to the ground. The operating potential is determined from the electro-chemical ...
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.
Various methods are used to prevent and protect against corrosion, such as cathodic protection, selection and injection of chemicals such as corrosion inhibitors or other ways to prevent corrosion. However, in order to see the results of these methods and how effective these measures are, corrosion monitoring should be done and, if necessary ...
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.
