Bolt Circle Diameter Solution

STEP 0: Pre-Calculation Summary
Formula Used
Bolt Circle Diameter = Outside Diameter of Gasket+(2*Nominal Bolt Diameter)+12
B = Go+(2*db)+12
This formula uses 3 Variables
Variables Used
Bolt Circle Diameter - (Measured in Millimeter) - Bolt Circle Diameter is the diameter of the circle on which the holes will be evenly distributed.
Outside Diameter of Gasket - (Measured in Millimeter) - Outside Diameter of Gasket is in which a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage.
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
Outside Diameter of Gasket: 1.1 Meter --> 1100 Millimeter (Check conversion here)
Nominal Bolt Diameter: 1.5 Meter --> 1500 Millimeter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
B = Go+(2*db)+12 --> 1100+(2*1500)+12
Evaluating ... ...
B = 4112
STEP 3: Convert Result to Output's Unit
4.112 Meter --> No Conversion Required
FINAL ANSWER
4.112 Meter <-- Bolt Circle Diameter

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

Bolt Circle Diameter Formula

Bolt Circle Diameter = Outside Diameter of Gasket+(2*Nominal Bolt Diameter)+12
B = Go+(2*db)+12

What is Bolt?

A bolt is a form of threaded fastener with an external male thread requiring a matching pre-formed female thread such as a nut. Bolts are very closely related to screws.

How to Calculate Bolt Circle Diameter?
