ASME B16.5 Pipe Flange Bolt Load

Calculate ASME B16.5 pipe flange bolt load, bolt stress and flange pressure.

Select a suitable bolt diameter and material type. The bolt load, bolt stress and flange pressure can be calculated from either the bolt design stress, a user defined bolt stress, a user defined bolt load, or a user defined flange pressure. The flange pressure is calculated with no gasket preload, or external loads such as bending moment. The bolt load equals the bolt stress times the tensile area. Tensile area is calculated for either ANSI or ISO threads. The gasket outside diameter can either be taken as the flange hub diameter, or be user defined.

CALCULATOR : ASME B16.5 Flange Design Bolt Load And Design Flange Pressure [FREE]   ±

Calculate ASME B16.5 flange bolt design load, design stress and flange design pressure.

The bolt tensile area can be calculated for either ANSI threads based on threads per inch, or ISO threads based on thread pitch. The design load is equal to the design stress times the tensile area. The flange design pressure is calculated with no gasket preload, bending moment, or external loads. For flanges with gasket preload, bending moment, or external loads, the design pressure can be used as an equivalent pressure (there are various formula to calculate an equivalent pressure).
