Seamless Pipe Weight Calculator
Calculate the theoretical mass of a round seamless stainless steel or nickel-alloy tube from outside diameter, wall thickness, length and nominal density. Then send the size directly to Junda for a technical quote.
Theoretical mass
- Weight per metre
- 16.383kg/m
- Weight per piece
- 98.296kg
- Total for 1 piece(s)
- 98.296kg
m = π × WT × (OD − WT) × ρ / 1000. Mass is in kg per metre when OD and WT are in mm and ρ is in g/cm³.
