Galvanized Steel Pipe
Coated in zinc, galvanized steel pipes are protected from oxidation and rust, which ultimately prevents deterioration of the pipe. They are a great option when you need to protect your steel pipes from a corrosive environment. The protective quality of galvanized pipe is created through a hot-dipping process, where the zinc then provides a protective layer that will rust away before any of the steel is affected. In terms of durability, a galvanized steel pipe can last well over 100 years, depending on the amount of corrosion exposure.

Galvanized Steel Pipe
Coated in zinc, galvanized steel pipes are protected from oxidation and rust, which ultimately prevents deterioration of the pipe. They are a great option when you need to protect your steel pipes from a corrosive environment. The protective quality of galvanized pipe is created through a hot-dipping process, where the zinc then provides a protective layer that will rust away before any of the steel is affected. In terms of durability, a galvanized steel pipe can last well over 100 years, depending on the amount of corrosion exposure.
Galvanized steel pipe maintains a wide range of benefits, suitable for use in highly corrosive environments. The semi-smooth, zinc finish of galvanized steel pipe provides a layer of protection that is not seen in other types of protective materials. The galvanized coating process protects the underlying steel from encountering corrosive elements that could deteriorate the steel and ultimately weaken its structural integrity. Main advantages of galvanized structural pipe include:
⦁ Protects against corrosion and rust
⦁ Increased structural longevity
⦁ Overall enhanced reliability
⦁ Affordable protection
⦁ Easy to inspect
⦁ Less repairs
⦁ Rugged toughness
⦁ Easier to maintain than standard painted pipes
⦁ Protected by advanced ASTM standardization

Hot dip galvanizing process
Workpiece degreasing → washing → pickling → washing → drying solvent dip fluxing preheated hot dip galvanized → cooling → finishing → rinsing → drying → passivation test
Cold-galvanized process
Chemical degreasing → washing → hot water hot water electrolysis degreasing → washing → washing → strong corrosive galvanized iron alloy → washing → washing → light → → washing → drying passivation
APPEARANCE OF HOT-DIP GALVANIZING AND COLD GALVANIZING
Cold galvanizing looks more smooth, bright, color passivation process plating layer is yellow-green in color, was colorful. Plating layer was bluish-white or white with white passivation process was green, white coating passivation process and the sun was significant Colorful angle. The complex workpiece angular edges parts prone to “electrical burning” from gloomy, the parts of the zinc layer thick. Yin corner site is easy to form a current dead undercurrent gray area and the area zinc layer is thinner. The workpiece overall zinc tumor, caking phenomenon.
Hot dip galvanized look a little rough compared to the electro-galvanized, silvery white, look prone process waterlines and a few drops of tumor is more obvious, especially in the one end of the workpiece. Hot dip galvanized zinc layer than a few times of the electro-galvanized thick corrosion protection is several times that of the electro-galvanized.
