    Weight Calculation of Butt Weld Pipe Fittings

    1. Weight Calculation of Pipe Elbows

    The weight of 90D Elbow Long Radius(ASME B16.9) equals to:

    0.0387 x S x (D-S) x R / 1000

    S - Wall thickness
    D - Outside Diameter of the Elbow
    R - Center Line Radius(Height)
    *All units are in mm.

    The weight of 45D Elbow Long Radius is half of 90D while the weight of 180D is twice of 90D.
    The weight of 90D Elbow Short Radius is two thirds of 90D Long Radius Elbow.

    2. Weight Calculation of Pipe Tees

    The weight of Equal Tee(ASME B16.9) equals to: 

    0.02466 x (S+1.5) x (D-S-1.5) x (3C-D/2) / 1000

    S - Wall thickness
    D - Outside Diameter of the tee
    C - Center to End Length
    *All units are in mm.

    The weight of primary class reducing tee is 94% of its equal type.
    The weight of second class reducing tee is 91% of its equal type.
    The weight of third class reducing tee is 89% of its equal type.
    The weight of fourth class reducing tee is 86% of its equal type.

    3. Weight Calculation of Pipe Reducers

    The weight of primary class reducer(concentric or eccentric) equals to:

    0.02466 x S x (D-S) x H / 1000

    S - Wall thickness
    D - Outside Diameter of the larger end of the reducer
    H - Total height of the reducer.
    *All units are in mm.

    The weight of second class reducer is 94% of its primary class.
    The weight of third class reducer is 91% of its primary class.
    The weight of fourth class reducer is 89% of its primary class.
