What Is Galvanized Steel Pipe?
Galvanized steel pipe is a carbon steel pipe that is coated with a protective layer of zinc. The zinc layer served as a sacrificial layer, it will get rust before the carbon steel underneath it.
Galvanized steel pipe includes Two types: hot dipped galvanized steel pipe and cold galvanized steel pipe. The galvanized layer will strengthen the anti-corrosion performance of steel pipe.
Galvanized Steel Pipe Types
Galvanized steel pipe include two kinds:
1. Hot dipped galvanized steel pipe.
2. Cold galvanized pipe, also called electric galvanized pipe.
Why Use Zinc As The Coated Layer?
Why use zinc? Because zinc element is more active than steel element. On one hand, the zinc oxide of galvanized steel pipe surface is compact, it can stop oxidation(corrosion). On the other hand, when electric-chemical corrosion has occurred, the first kind of metal corrupted is zinc rather than steel. The zinc layer effect is stop corrosion speed and prolongs the life of steel pipe.
