Gasket Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Gasket Factor = (Total Fastener Force-Inside Area of Gasket*Test Pressure)/(Gasket Area*Test Pressure)
m = (W-A₂*P_test)/(A₁*P_test)
This formula uses 5 Variables

Variables Used

Gasket Factor - Gasket Factor the 'm' value, referred to as the maintenance factor, is the compressive load required on the gasket to maintain the seal once pressurised.
Total Fastener Force - (Measured in Newton) - Total Fastener Force produces applied flange pressure to compress and seal the gasket.
Inside Area of Gasket - (Measured in Square Meter) - Inside Area of Gasket is the space inside the shape. It's a measure of 2-D space, and the units for area are squared ("length squared").
Test Pressure - (Measured in Pascal) - Test Pressure is based on the maximum design pressure of the system, and for a pressure vessel based on the maximum allowable working pressure (MAWP) of the vessel.
Gasket Area - (Measured in Square Meter) - Gasket Area is the area of contact the gasket is placed to seal between two flange connections.

STEP 1: Convert Input(s) to Base Unit

Total Fastener Force: 97 Newton --> 97 Newton No Conversion Required
Inside Area of Gasket: 13 Square Meter --> 13 Square Meter No Conversion Required
Test Pressure: 0.39 Pascal --> 0.39 Pascal No Conversion Required
Gasket Area: 99 Square Meter --> 99 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

m = (W-A₂*P_test)/(A₁*P_test) --> (97-13*0.39)/(99*0.39)

Evaluating ... ...

What is Gasket?

Gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression.

How to Calculate Gasket Factor?

Gasket Factor calculator uses Gasket Factor = (Total Fastener Force-Inside Area of Gasket*Test Pressure)/(Gasket Area*Test Pressure) to calculate the Gasket Factor, Gasket Factor is the ratio of residual unit stress on the gasket to internal pressure of the system. Gasket Factor is denoted by m symbol.

How to calculate Gasket Factor using this online calculator? To use this online calculator for Gasket Factor, enter Total Fastener Force (W), Inside Area of Gasket (A₂), Test Pressure (P_test) & Gasket Area (A₁) and hit the calculate button. Here is how the Gasket Factor calculation can be explained with given input values -> 2.318182 = (97-13*0.39)/(99*0.39).

FAQ

What is Gasket Factor?

Gasket Factor is the ratio of residual unit stress on the gasket to internal pressure of the system and is represented as m = (W-A₂*P_test)/(A₁*P_test) or Gasket Factor = (Total Fastener Force-Inside Area of Gasket*Test Pressure)/(Gasket Area*Test Pressure). Total Fastener Force produces applied flange pressure to compress and seal the gasket, Inside Area of Gasket is the space inside the shape. It's a measure of 2-D space, and the units for area are squared ("length squared"), Test Pressure is based on the maximum design pressure of the system, and for a pressure vessel based on the maximum allowable working pressure (MAWP) of the vessel & Gasket Area is the area of contact the gasket is placed to seal between two flange connections.
