Comprehensive guide to steel pipe weight calculator
Includes two calculation tools: weight by foot and general steel pipe weight calculation, and their suitable application scenarios, as well as error control optimization, etc.
Pipe Weight per Foot Calculator
This scenario is only applicable to scenarios with inches and feet as units. It can quickly estimate the weight of each foot of steel pipe.
Calculation formula
General formula:
Weight (lb/ft) = (OD−t)×t×10.69Weight (lb/ft) = (OD−t)×t×10.69
Where:
ODOD: Outside diameter (inch)
tt: Wall thickness (inch)
Factor 10.6910.69: Simplified value based on steel density 0.2836 lb/cubic inch0.2836 lb/cubic inch.
Example:
For a steel pipe with an outside diameter of 2 inch and a wall thickness of 0.2 inch0.2inch, the weight per foot is:
(2−0.2)×0.2×10.69=3.85 lb/ft(2−0.2)×0.2×10.69=3.85 lb/ft
Scope of application
Applicable to some scenarios where the weight of each foot of pipe needs to be quickly estimated.
General Steel Tube Weight Calculator
This calculation tool is very suitable for calculating shapes such as round and rectangular tubes and any irregular shapes. It is also suitable for unit weight calculations and is suitable for situations where the calculation needs to be more accurate.
Based on outer diameter and wall thickness:
Weight (kg) = 0.02466×t×(OD−t)×LWeight (kg) = 0.02466×t×(OD−t)×L
Where:
LL: length (meter)
ODOD and tt units must be unified in millimeters.
Based on volume and density:
Weight (kg) = π4×(OD2−(OD−2t)2)×L×ρWeight (kg) = 4π×(OD2−(OD−2t)2)×L×ρ
ρρ is the density of steel (7.85 g/cm37.85g/cm3).
Rectangular tube calculation formula
Weight (kg) = 2×(a+b−2t)×t×L×ρWeight (kg) = 2×(a+b−2t)×t×L×ρ
a and b: outer dimensions of the long and short sides (mm).
Tool implementation method
Excel template: Input parameters such as outer diameter and wall thickness, and automatically calculate through formula.
Professional software: For example, SolidWorks can directly generate mass properties through 3D modeling.
Online calculator: After inputting parameters, output the results with one click, and support multiple unit switching.
Error control and optimization suggestions
Formula correction:
In precise scenarios, it is recommended to use the volume method for calculation, and the acceptable error range of the simplified formula is 1%∼3%.
The density of stainless steel needs to be adjusted to 7.93 g/cm37.93g/cm3.
Data verification:
Compare with manual standard values (such as ASTM, JIS specifications).
Use a high-precision electronic scale to calibrate the calculation results.
Tool selection:
For large tools, professional software should be given priority, and Excel templates are recommended for small projects.
