Rico Steel manufactures and stocks stainless steel fittings across all standard sizes and grades. The Stainless Steel Fittings Calculator computes the theoretical weight of a fitting from its dimensions and grade density. Inputs cover fitting type, outside diameter, wall thickness or inside diameter, length and quantity. Output is unit weight in kilograms plus total consignment weight. Elbows, tees, reducers, caps and flanges hold different metal volumes at the same nominal bore, so the SS Fittings Weight Calculator applies a separate geometry factor to each type.

Theoretical weight from fitting dimensions and grade density. Results update as you type.
Results are theoretical weights. Actual fitting weight varies with manufacturing tolerances; verify against weighbridge figures.
How to Use the Stainless Steel Fittings Calculator
Select the fitting type first, then the grade. Grade selection sets the density automatically: austenitic 304 and 316 are set at 8.00 g/cm³, while ferritic 430 drops to 7.70 g/cm³. Enter outside diameter, wall thickness or inside diameter and the centre-to-end length in millimetres. Add the piece quantity last. The Stainless Steel Fittings Weight Calculator returns unit weight alongside total consignment weight, allowing you to cross-check both figures against the mill test certificate.
The formula describes a fitting as a hollow cylinder, then applies a geometry factor for curved bodies. Keep units consistent: millimetres for all dimensions, g/cm³ for density.
Volume: metal cross-section multiplied by developed length
Density: 7.70 to 8.00 g/cm³ across common stainless grades
OD: outside diameter measured across the body
ID: inside diameter, equal to OD minus twice the wall thickness
Length: centre-to-end or face-to-face dimension per ASME B16.9
Weight: theoretical mass, verified against actual weighbridge figures
SS Fittings Weight Calculation
Geometry determines the difference between fitting types. A 90-degree-long radius elbow uses a developed length of 1.57 times its centre-to-end dimension, because the bend follows an arc rather than a straight run. Reducers calculate the average of the large and small end diameters. Caps, stub ends and tees each carry their own form factor. Once you choose the fitting type, the correct factor applies automatically.
