WebBolt torque is calculated for a flanged assembly using the following equation. Applied Torque, T= (k∙f∙d)/12 in FPS Unit Where: T=Torque in ft-lb k=Dimensionless nut factor or tightening factor f=axial force in pounds d=Nominal bolt diameter in inches In the Metric System, Torque Applied, T = (k.d.f)/1000 where T = Torque in N-m f = Bolt load in N WebThe principle of a flanged connection is based on the load applied to the bolts, which causes the gasket to cover the macroscopic and microscopic imperfections of the flange face, managing to contain the fluid within the pressurized system.
WebJun 2, 2024 · The alignment of the flange bolts must be within 3 mm (1/8 inch) maximum offset. • Check if the flanges are co-axial or parallel before you insert the gasket in between the flange pipe.

WebA flange consists of three subcomponents: the flange ring, the gasket and the bolting. The successful operation of the flange depends on the correct choice, design and assembly of these subcomponents. The external bolted joints will require re-tightening in a uniform, diametrically staggered pattern. Challenge The sequence has been used for pipe flanges on both ASME B16.5 and ASME B16.47 flanges (NPS 26 inch and above), heat exchangers, and other applications like butterfly valves.
