Galvanized Steel Pipe
China Galvanized Pipe Wuxi Tube square Carbon Steel Pipe
Product Description
Galvanized steel pipe is a steel pipe that is coated with a layer of hot-dip galvanizing or electro-galvanizing on the surface of welded steel pipe. Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for conveying water, gas, oil and other general low-pressure fluids, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, oil heaters, condensing coolers, coal distillation and washing oil exchangers for chemical coking equipment, and trestle pipe piles and support frames in mine tunnels.
Types of galvanizing processes for hot and cold water pipes
Hot-dip galvanizing
To make galvanized steel pipes, steel materials are placed in a 450-degree Fahrenheit zinc bath. This process is also called hot-dip galvanizing. In this process, the two metals are chemically bonded to each other so that they never separate, resulting in a more corrosion-resistant and longer-lasting steel. Hot-dip galvanizing is currently considered one of the best methods for galvanizing steel pipes due to its durability and corrosion resistance.
Electroplating
Electroplating is another popular method for galvanizing steel pipes due to its high quality gloss and relatively cheap cost compared to other methods such as hot dip galvanizing. Electroplating is the process of depositing a thin layer of chromium, nickel or zinc on an existing metal surface using an electric current. Cold galvanizing is electroplating of zinc. The amount of zinc applied is very small, only 10-50g/m², and its corrosion resistance is much worse than that of hot dip galvanized pipes.
