What is the weight calculation formula of seamless carbon steel pipe?

In modern industrial production activities, steel structures are important basic components, and the type and weight of steel pipes selected will directly affect the quality and safety of buildings. When calculating the weight of steel pipes, carbon steel pipes are generally used. So, how to calculate the weight of carbon steel pipe (cs pipe)?

1. Carbon steel pipe weight calculation formula:
kg/m = (Od - Wt) * Wt * 0.02466
Formula: (outer diameter - wall thickness) × wall thickness mm × 0.02466 × length m

Example: carbon steel pipe outer diameter 114mm, wall thickness 4mm, length 6m
Calculation: (114-4)×4×0.02466×6=65.102kg

Due to the allowable deviation in the manufacturing process of steel, there is a certain difference between the theoretical weight calculated by the formula and the actual weight, so it is only used as an estimation reference. This is directly related to the length dimension, cross-sectional area and dimensional tolerance of the steel.

2. The actual weight of the steel refers to the weight obtained by actually weighing (weighing) the steel, which is called the actual weight.
Actual weight is more accurate than theoretical weight.

3. Calculation method of steel weight

(1) Gross weight: It is the symmetry of "net weight", which is the total weight of steel itself and packaging materials.
The shipping company calculates the freight by gross weight. However, the purchase and sale of steel products are calculated by net weight.
(2) Net weight: It is the symmetry of "gross weight".
The weight of the gross weight of the steel minus the weight of the packaging material, that is, the actual weight, is called the net weight.
In the purchase and sale of steel products, it is generally calculated by net weight.
(3) Tare weight: the weight of steel packaging material, called tare weight.
(4) Weight ton: the unit of weight used when calculating freight based on the gross weight of steel.
The legal unit of measurement is ton (1000kg), and there are also long tons (UK 1016.16kg) and short tons (US 907.18kg).
(5) Billing weight: also known as "billing ton" or "freight ton".

4. The weight of the steel for which the transportation department charges the freight.

Different shipping methods have different calculation standards and methods.
Such as railway vehicle transportation, generally the marked load of the truck is used as the chargeable weight.
Road transport is charged according to the tonnage of the vehicle.
For railway and road less-than-truckload transportation, the minimum chargeable weight is calculated based on the gross weight of a few kilograms, and any deficiency is made up.
