Galvanized Steel Pipe

※   Cold galvanized pipe is electric galvanized, galvanized amount is very small, only 10-50g/m2, its own corrosion resistance is much different than hot galvanized pipe.

※   Hot-dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highways, Bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries.

※   Nominal wall thickness (mm) : 2.0, 2.5, 2.8, 3.2, 3.5, 3.8, 4.0, 4.5 Coefficient parameter (c) : 1.064, 1.051, 1.045, 1.040, 1.036, 1.034, 1.032, 1.028.
