1.Galvanization pipe classified into hot galvanized and electric-galvanized two kinds. The hot dipped galvanized pipe have very thick zinc coating and coating uniformity so that its adhesion very strong, service life also very long. Compared with hot dripped galvanized, electric-galvanized with the advantages of low cost and stronger corrosion resistance, though its surface is not very smooth.
2.Weight coefficient
1)Nominal wall thickness 2.0 2.5 2.8 2.8 3.5 3.8 4.0 3.2 mm
2)Coefficient c 1.064 1.051 1.045 1.064 1.036 1.034 1.032 1.051
3)Steel grades: Q215A;Q215B;Q235A;Q235B
4)Test pressure value/Mpa: D10.2 168.3 mm for 3 Mpa;D177.8-323.9 mm to 5 mpa.
5)Galvanized pipe theory weight formula: (diameter-wall thickness) * thickness * 0.02466 * 1.0599 = weight per meter (kg/m)

Galvanized Steel Pipe is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing. galvanized steel pipe price is also sometimes called galvanized iron pipe. Galvanized steel pipe has been coated with a layer of zinc. The zinc provides a barrier against corrosion so that the pipe may be exposed to the outdoor environmental elements.Galvanized Steel Pipe The protective barrier proves equally effective against damage from indoor humidity.galvanized steel pipe price is covered with a zinc material to make the steel pipe more resistant to corrosion.
