    FIT

    ASME B16.9 Fittings Size & Weight

    Reference dimensions and estimated weights for ½″–24″ butt-weld fittings.

    Choose the fitting specification.

    Dimensions follow ASME B16.9 reference geometry. Weight is an engineering estimate based on nominal wall and density; confirm final weight and availability against the manufacturer’s data before ordering.

    FLG

    Flange Size & Weight Library

    ASME B16.5 reference library for ½″–24″ flanges, Classes 150–2500.

    Choose the flange specification.

    ASME B16.5 reference OD with indicative thickness and calculated weight. Facing, hub geometry, bore, drilling and manufacturing tolerances affect commercial weight. Confirm against the applicable standard and manufacturer drawing before ordering.

    PIP

    Pipe Size & Weight Calculator

    ASME B36.10 / B36.19 reference sizes for ½″–24″ pipe.

    Choose the pipe specification.

    Weights use nominal outside diameter, wall thickness and selected material density. Confirm tolerances and commercial weight against the applicable mill standard before ordering.

    FST

    Smart Fasteners Centre

    Estimate weights, check common grade pairings and send a complete fastener RFQ.

    Size & Weight Calculator

    Select the fastener details.

    Grade Compatibility Checker

    Select a stud or bolt grade.

    Smart Fastener RFQ

    Calculated weights are engineering estimates based on simplified geometry. Pairings are common references only; verify dimensions, thread series, temperature, coating and project specification before ordering.
