How to calculate the weight of carbon steel pipe

How to calculate the weight of carbon steel pipe? In modern industrial production activities, steel structure is an important basic component, and the type and weight of the steel pipe selected will directly affect the quality and safety of the building. When calculating the weight of steel pipes, carbon steel pipes are generally used. So, how to calculate the weight of carbon steel pipe & tubing? 1. Carbon steel pipe & tubing 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 & tubing outer diameter 114mm, wall thickness 4mm, length 6m Calculation: (114-4)×4×0.02466×6=65.102kg Due to the allowable deviation of the steel in the manufacturing process, the theoretical weight calculated by the formula is somewhat different from the actual weight, so it is only used as a reference for estimation. This is directly related to the length dimension, cross-sectional area and size tolerance of the steel. 2. The actual weight of the steel refers to the weight obtained by the actual weighing (weighting) of the steel, which is called the actual weight. The actual weight is more accurate than the 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 transportation company calculates the freight according to the gross weight. However, the purchase and sale of steel is calculated by net weight. (2) Net weight: It is the symmetry of “gross weight”. The weight after subtracting the weight of the packaging material from the gross weight of the steel, 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 the steel packaging material, called the tare weight. (4) Weight ton: the unit of weight used when calculating freight charges based on the gross weight of steel. The legal unit of measurement is the ton (1000kg), and there are also long tons (1016.16kg in the British system) and short tons (907.18kg in the US system). (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 transportation methods have different calculation standards and methods. Such as railway vehicle transportation, generally use the marked load of the truck as the billing weight. For road transport, the freight is charged based on the tonnage of the vehicle. For the less-than-truckload of railways and highways, the minimum chargeable weight is based on the gross weight of several kilograms, and rounded up if it is insufficient. Post time: Feb-16-2023
