2016 factory supply new product Galvanized pipe 3/4" 1.5 2 stain less steel Q235 lowest price building materials / Hot-dip Galvanized steel pipes
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)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)
