Common Pipe Fittings Product Weight/Volume Table Instructions for Use

1. The weights of the fittings listed in this table are calculated based on the outside diameter and wall thickness specified in relevant standards

such as ASME B16.9/ASME B16.11, and taking into account the impact of manufacturing processes and material selection on product weight (such as thickness compensation).

Therefore, the weight listed in this table is an approximate net weight of a single item for reference only.

The weight of stainless steel fittings with an "S" in the fitting number is listed, and the weight of other carbon steel fittings is listed. When checking the weight of stainless steel fittings,

please note that the wall thickness value of the same fitting number for carbon steel and stainless steel may be different.

2. The weight calculation formula for a 90° elbow is: W = 9.685*10-6R(D2-d2)

W - weight of a 90° elbow, kg;

R - the curvature radius (structural size), mm;

D - outside diameter of the elbow, mm;

d - inside diameter of the elbow, mm.

The weight formula for elbows uses the specific gravity of carbon steel, i.e. 7.85 kg/dm3, for calculation.

The weight of a 45° or 180° elbow is calculated as 1/2 and 2 times that of a 90° elbow, respectively.

3. The weight calculation formula for a steel pipe is: W = 0.0 Q = Wt/T

Q - Estimated weight of welded fittings, kg;

W - Wall thickness of the same nominal size listed in the table, product weight, kg;

t - Estimated wall thickness of welded fittings, mm;

T - Wall thickness of the same nominal size listed in the table, mm.

5. The approximate volume shown in the table is the approximate volume of the package occupied by a single product for reference.
