Causes of corrosion of liquefied gas storage tanks
① Crevice corrosion
Crevice corrosion or oxygen collection cell corrosion is corrosion that occurs when certain deposits or attachments occur on the metal surface.
② Etching and corrosion
There may be a stone clogged in the tube of the copper alloy condenser. At this point, turbulence will immediately occur in the downstream direction of the stone. This will cause corrosion or wear of the copper protective oxide film and expose unprotected copper alloy metal, causing further corrosion.
③ Pitting corrosion
Generally caused by defects in the metal surface. The reaction repeats and metal perforation occurs rapidly.
④Electrochemical corrosion
Galvanic corrosion occurs when two or more dissimilar metals touch and connect in the presence of a conductive liquid electrolyte. The above are all causes of corrosion of liquefied gas storage tanks.
