The service life of galvanized steel pipe fittings is long, but the service life is different in different environments: 13 years in heavy industrial areas, 50 years in oceans, 104 years in suburbs, and 30 years in cities. The yellow water is directly caused by galvanizing. Due to the threaded connection, the galvanized layer will be damaged at the joint, and rust will occur, which is caused by the iron oxide produced by iron oxidation entering the water.
With the development of industry, hot-dip galvanized products have been used in many fields. The advantage of hot-dip galvanized is that it has a long anti-corrosion period and adapts to a wide range of environments. It has always been a very popular anti-corrosion treatment method. It is widely used in power towers, communication towers, railways, road protection, lampposts, marine components, building steel structure components, substation ancillary facilities, light industry, etc.
Galvanized steel pipe has a long corrosion-resistant life. The principle of spraying aluminum and zinc-sprayed anti-corrosion coating on steel structures is cathodic protection. In a corrosive environment, even if the anti-corrosion coating is partially damaged, galvanized steel pipe still can sacrifice itself to protect the steel effect.
Galvanized steel pipes are divided into two methods: arc spraying and flame spraying. Compared with flame spraying, arc spraying greatly improves work efficiency and work safety. The bonding force of the coating is also far greater than that of flame spraying, so the quality of the coating can fully meet the needs of long-term anticorrosion. In the United States, the cost of using arc spraying anti-corrosion construction is lower than that of heavy anticorrosion paint, so the most spraying technology is steel The most effective way to prevent corrosion of structures.
