How Much Do You Know About Galvanization?
Usually, the galvanization what people said is the hot dipped galvanization. The hot-dip galvanizing process is an efficient way to protect steel pipes from rust and corrosion. Galvanization is an alloy layer produced by the reaction between metallic zinc water and the body of steel pipes. There are some the below steps to hot dipped galvanize the steel pipes.
A. Surface cleaning of the steel pipe
The surface of the steel pipe must be free of oils, grease, and rust. Put the pipeline into a zinc chloride aqueous solution for cleaning.
B. Galvanizing
Once the steel pipes have been cleaned and prepared, it is dipped into a bath of molten zinc, which is typically maintained at a temperature about 460 deg C for a certain time. The thickness of the galvanized coating can vary depending on the requirements of the application. The mass we supplied is equal or more than 610g/sqm.
C. Cooling and coating passivation solution
Remove them from the bath and let them cool down. Passivation liquid can play an auxiliary role in anti-corrosion.
D. Inspection before shipment
After the steel pipes have been galvanized, it is inspected to ensure that the coating is uniform and meets the required specifications, any defects or irregularities are corrected before they are shipped to the customer.
This kind of the hot-dip galvanizing method produces high-quality, uniform layer and durable galvanized products. They are often used in fields such as fire protection, construction, drainage, irrigation, etc.
