Galvanized pipes
Galvanized pipes are the pipes that a layer of protective zinc coating to pipe in order to prevent premature rust and corrosion. There are several different processes for galvanizing steel pipe,Hot-Dip Galvanizing and Electrogalvanizing are the most commonly used ways for steel pipes.To distinguish the Galvanized steel pipe and Electrogalvanized steel pipe,you should understand the manufacturing process of them.

1.The zinc layer
The thickness of hot dip galvanized zinc layer can achieved more than 50 microns, the maximum can reach 100 microns.Electro-galvanized zinc layer generally in the 3 to 5 microns, special requirements can also reach 7 to 8 microns.
2.Appearance
hot dip galvanization has dull, unpleasant finish.However, Electro-galvanization comes with excellent finish.
3.Life
Hot dip galvanized pipe is known to have very high life averaging between 20 to 50 years.But, lectro-galvanization has very low life, ranging from several months to some years only.
4.Costs
The cost is said to increase proportionately with higher coating thickness.hence the hot dip galvanized pipe with normal coat thickness about 40% expensive than electro-galvanizing pipe.
