Galvanizing Process & Description
Hot dip Galvanized Steel Pipe is created through a reaction between molten metal and an iron matrix to produce an alloy layer, effectively combining the matrix and the coating.
The production process begins with pickling the steel pipe. It is then cleaned in a tank containing an aqueous solution of ammonium chloride, zinc chloride, or a mixed aqueous solution of both, before finally entering the hot dip plating tank.

Frequently Asked Questions (FAQ)
What are the size specifications for seamless pipes?
Seamless pipes are available in sizes ranging from 1/2” to 24”, with nominal diameters from DN15 to DN600, and outside diameters from OD 21.3MM to 609.6MM.
What are the size specifications for welded pipes?
Welded pipes are available in sizes ranging from 1/2” to 48”, with nominal diameters from DN15 to DN1200, and outside diameters from OD 21.3MM to 1219.2MM.
How is hot dip galvanized steel pipe produced?
The pipe undergoes a pickling process first, followed by cleaning in an aqueous solution of ammonium chloride, zinc chloride, or a combination of both. It is then immersed into a hot dip plating tank where molten metal reacts with the iron matrix to form an alloy layer.
What are the main advantages of hot dip galvanized steel pipes?
They offer strong corrosion resistance, high resistance to rust, a long service life, and a relatively economical price.
Which industries commonly use hot dip galvanized steel pipes?
They are widely used in greenhouses, construction, machinery, railway vehicles, the automobile industry, fire protection, electric power, and highway infrastructure.
What processing methods are available for these steel pipes?
The available production methods include hot rolled, hot expanded, cold drawn, and hot galvanized processes.
