Cathodic protection<\/a> protects underground propane tanks<\/a> and\/or metallic gas piping from corrosion or rust.<\/p>\n Corrosion is a natural process that can cause costly damage to your business or residence.<\/p>\n Cathodic protection is a simple method of protection that works by connecting the metal that we want to protect to a more easily corroded \u201csacrificial metal.\u201d The active, sacrificial method acts as an anode and the protected metal becomes a cathode. This means that the sacrificial metal corrodes instead of the protected metal.<\/p>\n Learn more about cathodic protection below.<\/p>\n Cathodic protection controls a metal surface\u2019s corrosion and is typically used to protect storage tanks, pipelines, offshore structures, and ships from corrosion. In some cases, cathodic protection can be used to prevent cracking from stress corrosion.<\/p>\n If you have metallic gas piping or an underground propane tank, it is critical to understand cathodic protection and how it can protect your equipment.<\/p>\n There are two main types of cathodic protection:<\/p>\n In this method, a more reactive metal, often zinc or magnesium, is connected to the structure. This sacrificial anode corrodes instead of the protected metal, thereby preventing the corrosion of the structure.<\/p>\n In this approach, an external source of direct current is used to counteract the corrosion process. This method is often used when the structure being protected is large or where the environment is too aggressive for sacrificial anodes to be effective.<\/p>\n Cathodic protection is a crucial technique for extending the lifespan of metallic structures and ensuring their safety and integrity, especially in environments where corrosion is a significant concern.<\/p>\n Some common applications of cathodic protection include:<\/p>\n There are several ways to protect your propane tank from metal corrosion and rust:<\/p>\n **With all the above protection measures, a cathodic protection test must be conducted by a professional with a reading of at least -0.85 volts**<\/b><\/p>\n Galvanization is also used for corrosion prevention of steel tanks. Cathodic protection is obtained by applying a layer of metallic zinc, by either hot-dip galvanizing or electroplating, to the protected object. Zinc is traditionally used because it is less expensive, it adheres well to steel, and it provides Cathodic protection to the steel surface in case of damage to the zinc layer.<\/p>\n Cathodic protection is a critical part of an underground gas piping system.
