Satic Equipment - Gasket

What is the purpose of a gasket?

• To increase friction between two surfaces

• To provide insulation between two surfaces

• To create a tight leak-proof seal between two joint surfaces

• To enhance the visual appearance of joints

Which of the following is a type of non-metallic gasket?

• Metal reinforced gasket

• Corrugated metal gasket

• Compressed Non Asbestos Fibre (CNAF)

• Spiral wound gasket

What is the maximum temperature for a gasket made of Red rubber?

• 200°F

• 1000°F

• 250°F

• 750°F

How is a Full Face Gasket dimensioned?

• O.D = O.D of Tongue, I.D = I.D of Tongue

• O.D = O.D of Male Face, I.D = Nominal O.D of Steel Pipe

• Self-Centering O.D = BCD - Bolt Diameter, I.D = Nominal O.D of Steel Pipe

• O.D = O.D of the Flanges, I.D = Nominal O.D of Steel Pipe

What unique characteristics does a spiral wound gasket possess?

• Resistance to low temperatures & low pressures

• Inability to adjust to changes in operating conditions

• Poor sealability with a large gasket area

• Resilience to high temperatures & high pressures

What is the function of the outer ring in a semi-metallic gasket?

• Centering gasketing portion between flanges

• Prevents internal extrusion of the gasket when compressed

• Limiting bolt load at proper compression

• Preventing external expansion of the gasket when compressed

Which type of gasket is designed for high pressure, high temperature, or highly corrosive applications?

• Lens Ring Gasket

• Solid Metal Gasket

• Flat Solid Metal Gasket

• Semi-Metallic Gasket
