Q235 Hot dipped Galvanized steel Pipes and tubes for water
1)The internal and external surface color bright, uniform; (2) The weld line is uniform, and each tube is tested by eddy current inspection; 3)The hot dip galvanizing process of steel pipe adopts high grade 99.995% no. 0 zinc ingot (highest purity), with strong anticorrosion ability; ④ The appearance of each finished hot-dip galvanized steel pipe is treated with special anticorrosion, thus further prolonging the service life of hot-dip galvanized steel pipe; ⑤ Zinc layer thickness enough; Outer diameter size standard; Good ellipticity; The length of the foot; Rolling groove does not crack; Hot-dip galvanized pipe, in order to improve the corrosion resistance of steel pipe, the general steel pipe is galvanized. Galvanized steel pipe is divided into hot dip galvanized and electric dip galvanized, hot dip galvanized layer thick, electric dip galvanized cost is low, the surface is not very smooth.
