Hot Dipped Hot Dipped Galvanized Iron Pipe, Galvanized Steel Pipe for Pipeline
Galvanized Iron Pipe, Galvanized Steel Pipe
Galvanized steel pipe is a welded steel pipe with a hot-dip or electroplated galvanized layer on its surface. Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized pipes have a wide range of applications. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially in marine oil fields. They are also used as pipes for oil heaters, condensers, and coal tar wash oil exchangers in chemical coking equipment, as well as pipes for support structures in wharf piles and mining tunnels.
Hot dip galvanized pipes produce an alloy layer by reacting molten metal with an iron substrate, thereby bonding the substrate and coating together. Hot dip galvanizing is the process of first pickling steel pipes. In order to remove iron oxide from the surface of the steel pipes, after pickling, they are cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to a hot-dip galvanizing tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. The hot-dip galvanized steel pipe substrate undergoes complex physical and chemical reactions with the molten plating solution, forming a corrosion-resistant and tightly structured zinc iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate, so its corrosion resistance is strong.
We also supply other pipeline steel pipes to meet diverse project demands, including anti-corrosion coating steel pipe and seamless steel tubes. These pipes are widely used for oil, gas, water transmission and industrial piping systems.

FAQ
Q: What is the difference between hot dipped galvanized pipe and electro-galvanized pipe?
A: Hot dipped galvanized pipe has thicker zinc coating and better corrosion resistance, which is the common choice for long-term outdoor and underground pipeline projects. Electro-galvanized pipe features thin coating for indoor light-duty use.
Q: What size range do you supply for galvanized iron pipe?
A: We supply DN6-DN150 galvanized steel pipe, wall thickness from 1.0mm to 10mm. Custom length and threaded processing are available.
Q: Can we customize the surface treatment?
A: Yes. We can provide PVC coating, painting, anti-rust oil and other surface treatments according to customer requirements.
