Outside Diameter of Flange using Bolt Diameter Solution

STEP 0: Pre-Calculation Summary
Formula Used
Outside Flange Diameter = Bolt Circle Diameter+2*Nominal Bolt Diameter+12
Dfo = B+2*db+12
This formula uses 3 Variables
Variables Used
Outside Flange Diameter - (Measured in Millimeter) - The Outside Flange Diameter is defined as the sum of four-times the value diameter of driving shaft and two times the thickness of protecting rim.
Bolt Circle Diameter - (Measured in Millimeter) - Bolt Circle Diameter is the diameter of the circle on which the holes will be evenly distributed.
Nominal Bolt Diameter - (Measured in Millimeter) - Nominal Bolt Diameter is the diameter equal to the external diameter of the threads or the overall diameter of the part.
STEP 1: Convert Input(s) to Base Unit
Bolt Circle Diameter: 4.1 Meter --> 4100 Millimeter (Check conversion here)
Nominal Bolt Diameter: 1.5 Meter --> 1500 Millimeter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Dfo = B+2*db+12 --> 4100+2*1500+12
Evaluating ... ...
Dfo = 7112
STEP 3: Convert Result to Output's Unit
7.112 Meter --> No Conversion Required
FINAL ANSWER
7.112 Meter <-- Outside Flange Diameter
(Calculation completed in 00.004 seconds)

17 Design of Pressure Vessel Subjected to Internal Pressure Calculators

Coefficient Value for Thickness of Flange
Go Coefficient Value for Thickness of Flange = ((1)/((0.3)+(1.5*Maximum Bolt Loads*Radial Distance)/(Hydrostatic End Force in Gasket Seal*Diameter of Gasket at Load Reaction)))
Gasket Factor
Go Gasket Factor = (Total Fastener Force-Inside Area of Gasket*Test Pressure)/(Gasket Area*Test Pressure)
Longitudinal Stress (Axial Stress) in Cylindrical Shell
Go Longitudinal Stress for Cylindrical Shell = (Internal Pressure given Longitudinal Stress*Mean Diameter of Shell)/4*Thickness of Cylindrical Shell
Internal Presure of Vessel given Longitudinal Stress
Go Internal Pressure given Longitudinal Stress = (4*Longitudinal Stress*Thickness of Cylindrical Shell)/(Mean Diameter of Shell)
Wall Thickness of Pressure Vessel given Longitudinal Stress
Go Thickness of Shell for Longitudinal Stress = (Internal Pressure for Vessel*Mean Diameter of Shell)/(4*Longitudinal Stress)
Wall Thickness of Cylindrical Shell Given Hoop Stress
Go Thickness of Shell for Hoop Stress = (2*Internal Pressure given Hoop Stress*Mean Diameter of Shell)/Circumferential Stress
Internal Pressure of Cylindrical Vessel given Hoop Stress
Go Internal Pressure given Hoop Stress = (2*Circumferential Stress*Thickness of Cylindrical Shell)/(Mean Diameter of Shell)
Circumferential Stress (Hoop Stress) in Cylinderical Shell
Go Circumferential Stress = (Internal Pressure for Vessel*Mean Diameter of Shell)/2*Thickness of Cylindrical Shell
Maximum Bolt Spacing
Go Maximum Bolt Spacing = 2*Nominal Bolt Diameter+(6*Thickness of Flange/Gasket Factor+0.5)
Hydrostatic End Force using Design Pressure
Go Hydrostatic End Force = (pi/4)*(Radial Distance^2)*Internal Pressure
Diameter of Gasket at Load Reaction
Go Diameter of Gasket at Load Reaction = Outside Diameter of Gasket-2*Effective Gasket Seating Width
Effective Thickness of Conical Head
Go Effective Thickness = Thickness of Conical Head*(cos(Apex Angle))
Hoop Strain
Go Hoop Strain = (Final Length-Initial Length)/(Initial Length)
Radial Distance from Gasket Load Reaction to Bolt Circle
Go Radial Distance = (Bolt Circle Diameter-Diameter of Gasket at Load Reaction)/2
Bolt Circle Diameter
Go Bolt Circle Diameter = Outside Diameter of Gasket+(2*Nominal Bolt Diameter)+12
Outside Diameter of Flange using Bolt Diameter
Go Outside Flange Diameter = Bolt Circle Diameter+2*Nominal Bolt Diameter+12
Minimum Bolt Spacing
Go Minimum Bolt Spacing = 2.5*Nominal Bolt Diameter

Outside Diameter of Flange using Bolt Diameter Formula

Outside Flange Diameter = Bolt Circle Diameter+2*Nominal Bolt Diameter+12
Dfo = B+2*db+12
