Weight coefficient of galvanized steel pipe

How to calculate the price per metre of hot-dip galvanizing? The price of hot-dip galvanized steel pipe is not difficult to calculate. Just remember that the formula knows the price per ton, 3 inch galvanized steel pipe, then the price per metre can be calculated according to the formula given below. There will be fluctuations in the day, we should always pay attention to the price changes, in order to calculate the more accurate price of hot-dip galvanized steel pipe.

Galvanized steel pipe weight formula: [(outer diameter – wall thickness) * wall thickness] * 0.02466 = kg / m (weight per meter), welded pipe, ordinary galvanized welded pipe 1.2 inch weight is 3.13kg / m, 1.5 inch weight is 3.84kg/m; thickened galvanized welded pipe 1.2 inch weight is 3.78/m, 1.5 inch weight is 4.58kg/m;

Weight coefficient of galvanized steel pipe:

Nominal wall thickness mm: 2.0, 2.5, 2.8, 3.2, 3.5, 3.8, 4.0, 4.5;

Coefficients c: 1.064, 1.051, 1.045, 1.040, 1.036, 1.034, 1.032, 1.028;

Steel grade: Q215A; Q215B; Q235A; Q235B;

Test pressure values: /Mpa: D10.2-168.3mm is 3Mpa; D177.8-323.9mm is 5Mpa.

How to calculate the price per metre of hot-dip galvanized steel pipe? Example calculation:

Expand all (outer diameter – wall thickness) * wall thickness * 0.02466 = weight per meter, multiplied by 1.03-1.06 galvanized layer. Generally multiplied by the galvanized layer coefficient of 1.03 is more accurate, which is the weight per metre of the final galvanized pipe, for example, the diameter is 20, the wall thickness of the city 2.0, as follows (20-2) * 2 * 0.02466 = 0.89 kg, and finally multiplied by plating The zinc layer coefficient of 1.03 is the weight of the galvanized steel pipe per meter. A detailed explanation is: a seamless steel pipe with an outer diameter of 60 mm and a thickness of 4 mm, for each m weight. Weight per m = 0.02466 × 4 × (60 – 4) = 5.52 kg.

Weigh a steel pipe and weigh it. If the steel pipe weighs 10 kg and is 6 meters long, the weight per meter = 10 kg / 6 m = 1.6667 kg / m. Assume that the steel pipe is 4,000 yuan / ton, which is 4.00 yuan / kg, the price per meter = 4.00 / kg × 1.6667 kg / m = 6.6668 yuan / m. Calculation formula = steel pipe weight / steel pipe length × steel pipe number / kg = 10 kg / 6 m × 4.00 yuan / kg = 6.6667 yuan / m.
