Regarding the calculation method of carbon steel pipe weight, many people do not know the theoretical weight calculation formula of carbon steel pipe
Calculation formula for steel pipe weight: (outer diameter – wall thickness) × Wall thickness mm × zero point zero two four six six × Length m Example: steel pipe 114mm (outer diameter) × 4mm (wall thickness) × 6m (length) calculation: (114-4) × four × zero point zero two four six six × 6=65.102kg Extended data Screw thread steel weight calculation formula: Formula: Diameter mm × Diameter mm × zero point zero zero six one seven × Length m Example: deformed steel Φ 20mm diameter × 12m (length) calculation: 20 × twenty × zero point zero zero six one seven × 12=29.616kg Round Steel Weight Calculation Formula: Diameter mm × Diameter mm × zero point zero zero six one seven × Length m Example: round steel Φ 20mm diameter × 6m (length) calculation: 20 × twenty × zero point zero zero six one seven × 6=14.808kg square steel weight calculation formula: side width (mm) × Side width (mm) × Length (m) × 0.00785 Example: square steel 50mm (side width) × 6m (length) calculation: 50 × fifty × six × 0.00785=117.75 (kg) Weight calculation formula for flat steel: side width (mm) × Thickness (mm) × Length (m) × 0.00785 example: flat steel 50mm (side width) × 5.0mm thick × 6m (length) calculation: 50 × five × six × 0.00785=11.775 (kg) Weight calculation formula for hexagonal steel: diameter on opposite side × Opposite diameter × Length (m) × 0.00068 example: hexagonal steel 50mm (diameter) × 6m (length) calculation: 50 × fifty × six × 0.0068=102 (kg) Steel plate weight calculation formula: 7.85 × Length (m) × Width (m) × Thickness (mm) Example: Steel plate 6m (length) × 1.51m wide × 9.75mm thick Calculation: 7.85 × six × one point five one × 9.75=693.43kg Weight calculation formula of flat pass: (side length+side width) × two × thick × zero point zero zero seven eight five × Length m Example: flat pass 100mm × 50mm × 5mm thick × 6m (length) calculation: (100+50) × two × five × zero point zero zero seven eight five × 6=70.65kg square tube weight calculation formula: side width mm × four × thick × zero point zero zero seven eight five × Length m Example: square passage 50mm × 5mm thick × 6m (length) calculation: 50 × four × five × zero point zero zero seven eight five × 6=47.1kg weight calculation formula for equal leg angle steel: (side width+side width) × thick × zero point zero zero seven six × Length m (rough calculation) Example: angle steel 100mm × 80mm × 8 thick × 6m (length) calculation: (100+80) × eight × zero point zero zero seven six × 6=65.67kg Weight calculation formula for unequal angle steel: side width mm × thick × zero point zero one five × Length m (rough calculation) Example: angle steel 50mm × 50mm × 5 thick × 6m (length) calculation: 50 × five × zero point zero one five × 6=22.5kg [other nonferrous metals] weight calculation formula for brass pipe: (outer diameter – wall thickness) × thick × zero point zero two six seven × Length: 20mm brass tube × 1.5mm thick × 6m (length) calculation: (20-1.5) × one point five × zero point zero two six seven × 6=4.446kg Copper Tube Weight Calculation Formula: (Outer Diameter Wall Thickness) × thick × zero point zero two seven nine six × Length: 20mm copper tube × 1.5mm thick × 6m (length) calculation: (20-1.5) × one point five × zero point zero two seven nine six × 6=4.655kg Weight calculation formula for aluminum flower board: length m × Width m × Thickness mm × 2.96 Example: Aluminum flower board 1m wide × 3m long × 2.5mm thick calculation: 1 × three × two point five × 2.96=22.2kg Brass plate: specific gravity 8.5 Copper plate: specific gravity 8.9 Zinc plate: specific gravity 7.2 Lead plate: specific gravity 11.37 Calculation method: specific gravity × Thickness=Theoretical weight of steel per square meter The theoretical weight of steel is calculated based on the nominal size and density of steel (formerly known as specific gravity), which is called the theoretical weight
Due to the allowable deviation of steel during 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.
