The applied external load. To prevent slip, it is essential to ensure adequate bolt preload, select appropriate materials and friction coefficients, optimize joint design, use an adequate number of bolts, employ proper tightening techniques, and perform regular maintenance and inspectionPurpose of calculation: Determine force distribution in a bolted joint.Calculation ReferenceMachine Design JuvinallScahum's Machine Design 'Torque Pretension' worksheet also consult with the following references Validation Material and basic geometry geometryYoung's modulus of boltPoisson ratio of boltYoung's modulus of clamped platePoisson ratio of clamped plateupper clamped plate thicknesslower clamped plate thicknesstotal clamped plate thickness2) Bolting detailsbolt diameterbolt thread root diameterbolt clearance holebolt head diameter(note: could be increased using a flanged headed bolt or a washer)thickness of bolt headnut thickness(note: enter 0 if threaded into flange)bolt length assumed equal total clamped plate thickness + hnut3) Torque Tightening and Bolt PreLoad CalculationMethod of torque tightening determines accuracy of bolt preload obtained.It is not unusual to increase bolt size because the torque tightening method cannot guarentee a minimum preload.The effects of the torque tightening method are shown on the joint diagram below.Variation in preload (+ and -)Tightening Torque (to yield bolt see Eqn. 37)Bolt head dimension across flatsThread pitchouter thread radiusinner thread radiusmean thread radiusEffective radius of rubbing surface against which head/nut bearsCoefficient of friction between screw and nut threadCoefficient of friction at head/nut bearing collarThread Lead (equals thread pitch for single thread screws)Angle of thread at mean radiusThread angle at bearing surfaceAngle between tangent to tooth profile (on the loaded side) and a radial lineThread ConstantBolt preload (load parallel to screw axis)Efficiency of the screw mechanism (ratio of useful work out to work in)Torque to stretch BoltThread Torque (torsional load in the bolt to stretch the bolt and overcome thread friction)Torque to overcome thread frictionTorque to overcome collar frictionJoint pretension constants to compare with other threadsTypical K factors for comparison purposesSteel Thread Condition0.30 as received, stainless on mild or alloy 0.20 as received, mild or alloy on same0.16 cadmium plated0.14 molybdenum-disulphide grease0.12 PTFE lubricationOff Torque - torque required to loosen the nut (if negative then torque needs to be applied to hold nut still)Bolt Pretension and material propertiesBolt ultimate tensile strengthBolt yield stressForce on joint at which bolt yields (ignoring torsional effects)% of bolt yield stress used by bolt preload4) Stiffness of tensile loadpathTensile stiffness of a bolt shaftShear stiffness of a bolt headShear stiffness of a nutTotal stiffness of bolt5) Stiffness of compressive loadpathcone angle (normally 45° dispersion from bolt head/nut)Compressive stiffness of clamped plates (in series)Shear stiffness of clamped platesTotal stiffness of all compressive loadpath elements under bolt6) Calculate Basic Joint ForcesForce in bolt when preload is lost (joint separates and contact force between clamped plates = 0)Fbreak/Fleak: resulting safety factor7) Calculate

In your piping system.By selecting an ANSI-compliant flange, you can be sure it will integrate flawlessly with other ANSI-compliant parts, lowering the possibility of leaks and malfunctions. Additionally, various industries prioritize safety and regulatory compliance to adhere to these standards.What are ANSI Flange Dimensions?The ANSI flanges key dimensions include inner and outer diameter and bolt-hole spacing. Let’s explore these dimensions and why they are crucial: Inner Diameter (I.D.):1. It is a measurement of the bore or opening in the center of the flange.2. The inner diameter defines the piping system’s flow capacity, and the flange’s inner diameter must match the connected pipes.3. Adequate alignment of the inner diameters with the connecting pipe prevents turbulence and pressure drops, ensuring efficient fluid flow.Outer Diameter (O.D.):1. It is the measurement of the outside edge of the flange.2. It helps determine the flange size and the required gasket size.3. The outer diameter should be compatible with the dimensions of the adjacent components to ensure a secure and leak-free connection.Bolt-Hole Spacing:1. It is the distance between the bolt holes set in a circular pattern on the flange.2. The number of bolt holes and their spacing depend on the flange size and pressure rating.3. Proper bolt-hole spacing is essential for uniform distribution of the bolt load, ensuring a tight seal and preventing leakage.4. The spacing should also match the mating flange for a secure connection.These dimensions are crucial for several reasons:1. Interchangeability: With an ANSI-compliant flange, you can be sure it will integrate with other components effortlessly. It lowers the possibility of leaks and malfunctions. 2. Safety: Proper dimensions prevent pressure-related failure of the flange. It is essential for both the system’s and the user’s safety.3. Leak Prevention: Precise specifications, inner and outer diameters, and bolt-hole spacing are essential for a tight seal. It stops leakage that can cause product loss, environmental harm, or safety risks.4. Efficiency: The matched inner diameter of the flange with the pipe’s inner diameter reduces turbulence and pressure drops, optimizing the efficiency of the fluid handling system.5. Consistency: Standardized dimensions make replacing or upgrading components within a pipe system easier by promoting consistency in design and production.Accessing ANSI Flange DimensionsANSI B16.5 StandardASME B16.5 standard includes Steel Pipe Flanges and changed fittings from NPS 1/2 to NPS 24 Metric/Inch in Pressure Classes 150 to 2500. It covers materials, dimensions, tolerances, marking, pressure-temperature ratings, testing, and processes of designating openings for pipe flanges and flanged fittings.Weld neck and blind flanges are two crucial flanges frequently used in pipe systems. “B16.5” and “B16 5” are interchangeable and refer to the same standard. However, keep in mind that the ASME B16 5 (ANSI B16 5) standard only addresses sizes up to 24 inches, as sizes
