Hot dip galvanized pipe, in order to improve the corrosion resistance of steel pipe, the general steel pipe galvanized. Hot dip galvanized steel pipe and electric galvanized two, hot dip galvanized layer thick, electric galvanized low cost, the surface is not very smooth.

Nominal wall thickness: mm2.0, 2.5, 2.8, 3.2, 3.5, 3.8, 4.0, 4.5;

Coefficient: c1.064, 1.051, 1.045, 1.040, 1.036, 1.034, 1.032, 1.028.

Note: the mechanical properties of steel are important indicators to ensure the operational properties (mechanical properties) of steel, which depend on the chemical composition of steel and the heat treatment system. In the steel tube standard, according to different requirements, the provisions of tensile properties (tensile strength, yield strength or yield point, elongation) and hardness, toughness indicators, as well as user requirements of high, low temperature performance. Brand of galvanized steel tube: Q215A; Q215B; Q235A; Q235B

Test pressure /Mpa: d10.2-168.3mm is 3Mpa; D177.8-323.9 mm to 5 mpa.
