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.

Tube size and material

Use millimetres. The calculation is theoretical and excludes mill tolerance, end finish and packing.

Nominal density 8 g/cm³

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.

The quote form opens with this size and material context. Junda confirms the applicable standard, tolerance, heat treatment, test programme and delivery terms in the written quotation.

Stainless steel pipe schedule reference

Outside diameter and wall thickness in millimetres. Calculated mass per metre uses the density selected above. This is a practical subset of ASME B36.19; verify the current standard edition before ordering.

How to use the result in an enquiry

Send the grade or UNS designation, outside diameter, wall thickness, length, quantity, applicable ASTM/ASME standard and inspection scope. If the tube is for a heat exchanger, add the U-bend radius, leg lengths and centre distance. Junda reviews the drawing and returns a technical quotation with the applicable mill test certificate and inspection documents.
