5 Ways to Avoid Galvanic Corrosion

The Causes of Galvanic CorrosionWays to Avoid Galvanic CorrosionInsulationElectrolyte IsolationSelection of Appropriate Contacting MetalsCorrosion InhibitorsMinimizing The Area RatioThe primary driving force in galvanic corrosion is a property known as potential difference. When a metal is immersed in an electrolyte, it adopts an electrode potential. The value of the electrode potential for various metals is represented in a table known as the galvanic series. The potential difference between the two metals is, therefore, the difference between their respective electrode potentials as defined in the galvanic series.When twSee more on corrosionpediaCATHODIC PROTECTION OF STAINLESS STEEL 316L (steel) pumps.

Sacrificial Anode - an overview ScienceDirect Topics

Magnesium and zinc are the most often used galvanic anodes for the cathodic protection of pipelines. 1416 The corrosion potential difference of magnesium with respect to steel is 1 V, which limits the length of the pipeline that can be protected by one anode. Economic considerations have led to the use of aluminum and its alloys.(pipe) Some results are removed in response to a notice of local law requirement.

Cathodic Protection. Cathodic protection refers to protecting metals from corrosion by making the metal a cathode (as opposed to the anode) and either providing a sacrificial anode or a source of electrons to act as an anode. Cathodic protection is interesting in that the user can control the amount of protection from corrosion; it can be stopped almost completely or to a lesser, quantifiable level of protection

Steel Pipeline - an overview ScienceDirect Topics

N. Saeed, H.R. Ronagh, in Rehabilitation of Pipelines Using Fiber-reinforced Polymer (FRP) Composites, 2015 10.1 Introduction. Steel pipelines have become the main network of oil and gas transmission over the last 50 years. In Europe alone, the total length of the gas transmission system has increased from about 30,000 km to over 120,000 km between 1975 and 2004 (EGIG, 2005).(pipe) The Basics of Cathodic Protection - Corrosionpedia(steel) Understanding Galvanic Or Bimetallic CorrosionCathodic Protection (CP) and Its Method of OperationTypes of Cathodic ProtectionLimitations of Cathodic ProtectionTo understand how cathodic protection works, we must first appreciate the basics of bimetallic corrosion, also known as galvanic corrosion. Bimetallic corrosion, as its name implies, is a unique type of corrosion that occurs between the pairing of two metals. This corrosion is observed in several situations where dissimilar metals are in direct or indirect contact with each other. Bimetallic corrosion is usually characterized by accelerated corrosion in one metal while the other remains unaffected. In other wordsSee more on corrosionpediaHow Stainless Steel Pipes Are Made - Beall Industry Group(steel) Stainless steel pipes are long, hollow tubes that are used for a variety of purposes. They are produced by two distinct methods which result in either a welded or seamless pipe. In both methods, raw steel is first cast into a more workable starting form.(pipe) The Pin Brazing Process Farwest Corrosion Control Company(steel) As for steel pipes, pin brazing either in the form of threaded brazing pins with nuts or cable is used. It gets brazed directly onto the pipe by means of a lug. As we know, Cathodic protection controls the corrosion of any metal surface by simply transforming that particular surface into the cathode of an electrochemical cell.

Does Stainless Steel Pipe Need Cathodic Protection - Beall Does Stainless Steel Pipe Need Cathodic Protection Beall

Appropriate cathodic protection can protect the passive film of stainless steel and reduce the uniform corrosion of the sample surface. When the metal surface is polarized by the cathode, the adsorption of Cl - on the metal surface is blocked, which avoids the destruction of the passivation film and reduces the risk of local corrosion.
