What is Galvanizing in Steel Pipes

Galvanization is the most common hot dip process used for industrial applications; this process is done by applying a zinc coating to iron or steel to resist rust. Galvanization is a versatile and easy way to provide corrosion resistance to protect building materials from damage due to atmospheric conditions. This protection method can be applied in two ways: as a continuous barrier by protecting the substrate from contact with the corrosive electrolyte and as a galvanic protection by slowly destroying itself in a corrosive aqueous environment.
 

The hot dip galvanizing process is carried out in two stages. First, the steel pipe is prepared to accept the zinc coating. The pipe is immersed in a molten zinc bath in the second step. This process allows the zinc to form a series of alloy layers with the base steel thick enough to meet certain required weight specifications.
 

Benefits and Uses of Galvanized Water Pipe
 

One of the most common and popular types of pipes today, galvanized pipes, is used in many areas of residential and commercial buildings. Generally, these pipes transport water, gas, and other liquid substances. These pipes, made of solid steel and extra zinc coating, can be in many forms.
 

Galvanized pipe features can be listed as follows:
 

The galvanized water pipe can significantly increase the resistance pressure of liquid substances as the pressure degree increases. Calculating the pressure of galvanized water pipe compared to other pipe types is also easy. Although galvanized pipe prices are slightly more costly than other pipe types due to the extra coating, their benefits are pretty high. The extra zinc coating in the galvanized installation pipe ensures that the pipe is thick and homogeneous. This way, the chance of spillage and loss of liquids transferred with galvanized pipe is minimized.
 

The galvanized pipe can provide more strength to any structure. Galvanized pipe always offers better support, highest strength, and consistent performance throughout the year, regardless of what is carried.
 

In short, galvanization creates a barrier that prevents corrosive substances from reaching the steel or iron below. The zinc acts as a temporary anode so that even if the coating is scratched, the remaining zinc protects the exposed steel. The zinc protects the base metal by corroding it before it does and reacts with the atmosphere to form a compact, cohesive patina that is insoluble in rainwater.
