Initial Bolt Torque given Bolt Load Solution

STEP 0: Pre-Calculation Summary

Formula Used

Initial bolt torque = Nominal Bolt Diameter*Bolt Load in Gasket Joint/11
m_ti = dn*F_b/11
This formula uses 3 Variables

Variables Used

Initial bolt torque - (Measured in Newton) - Initial bolt torque is defined as initial twisting force acting on bolt.A force that tends to cause rotation.
Nominal Bolt Diameter - (Measured in Meter) - Nominal bolt diameter is the size most commonly associated with screw threads is the nominal diameter.
Bolt Load in Gasket Joint - (Measured in Newton) - Bolt Load in Gasket Joint is defined as the load that is applied by the bolts onto the gasketed joint.

STEP 1: Convert Input(s) to Base Unit

Nominal Bolt Diameter: 2.8 Millimeter --> 0.0028 Meter (Check conversion here)
Bolt Load in Gasket Joint: 18150 Newton --> 18150 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

m_ti = dn*F_b/11 --> 0.0028*18150/11

Evaluating ... ...

m_ti = 4.62

STEP 3: Convert Result to Output's Unit

4.62 Newton --> No Conversion Required

FINAL ANSWER

4.62 Newton <-- Initial bolt torque

Bolt Load given Modulus of Elasticity and Increment Length

Go Bolt Load in Gasket Joint = Modulus of Elasticity*Incremental Length in Direction of Velocity/((Length of joint 1/Area of cross section at the inlet)+(Length of joint 2/Area of cross section at the throat))

Twisting Moment given Flange Pressure

Go Twisting Moment = (Flange pressure*Gasket Area*Torque Friction Coefficient*Diameter of Bolt)/(2*Number of Bolts)

Flange pressure given Twisting moment

Go Flange pressure = 2*Number of Bolts*Twisting Moment/(Gasket Area*Torque Friction Coefficient*Diameter of Bolt)

Flange pressure developed due to tightening of bolt

Go Flange pressure = Number of Bolts*Bolt Load in Gasket Joint/(Gasket Area*Torque Friction Coefficient)

Gasket Area given Flange pressure

Go Gasket Area = Number of Bolts*Bolt Load in Gasket Joint/(Flange pressure*Torque Friction Coefficient)

Number of Bolts given Flange pressure

Go Number of Bolts = Flange pressure*Gasket Area*Torque Friction Coefficient/Bolt Load in Gasket Joint

Bolt Load given Flange pressure

Go Bolt Load in Gasket Joint = Flange pressure*Gasket Area*Torque Friction Coefficient/Number of Bolts

Width of u collar given uncompressed Gasket Thickness

Go Width of u-collar = ((Uncompressed gasket thickness)*(100-Minimum Percentage Compression))/100

Uncompressed gasket thickness

Go Uncompressed gasket thickness = (100*Width of u-collar)/(100-Minimum Percentage Compression)

Minimum percentage compression

Go Minimum Percentage Compression = 100*(1-(Width of u-collar/Uncompressed gasket thickness))

Nominal Bolt Diameter given Bolt Load

Go Nominal Bolt Diameter = 11*Initial bolt torque/Bolt Load in Gasket Joint

Initial Bolt Torque given Bolt Load

Go Initial bolt torque = Nominal Bolt Diameter*Bolt Load in Gasket Joint/11

Bolt load in gasket joint

Go Bolt Load in Gasket Joint = 11*Initial bolt torque/Nominal Bolt Diameter

Initial Bolt Torque given Bolt Load Formula

Initial bolt torque = Nominal Bolt Diameter*Bolt Load in Gasket Joint/11
m_ti = dn*F_b/11
