Galvanized Steel Pipe Weight Coefficient
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.
Note: The mechanical properties of steel are important indicators to ensure the final performance (mechanical properties) of steel, which depend on the chemical composition and heat treatment system of the steel. In the steel pipe standards, according to different usage requirements, tensile properties (tensile strength, yield strength or yield point, elongation), hardness, toughness indicators, and high and low temperature performance required by users are specified.

Usage of Galvanized Steel Pipes
Instructions for Use of Galvanized Steel Pipes
The commonly referred galvanized pipes, the type of iron pipes used for gas and heating, are also galvanized pipes. As water pipes, after using for several years, a large amount of rust scale is produced inside the galvanized pipes. The yellow water flowing out not only pollutes the sanitary ware but also contains bacteria that breed on the rough inner walls. The rust corrosion causes the content of heavy metals in the water to be too high, which severely endangers human health
