Types of gaskets and gasket fundamental

What is the purpose of using gaskets in metal to metal surface joints?

• To increase the strength of the joint

• To reduce the weight of the joint

• To fill microscopic surface irregularities

• To improve the conductivity of the joint

What is the amount of force required to make a gasket flow and seal the surface irregularities known as?

• Compression load

• Residual force

• Operating stress

• Seating force

Which type of gasket is widely used on high pressure joints?

• Nonmetallic gasket

• Semi-metallic gasket

• Metallic gasket

• Ring joint gasket

What is the function of the outer ring in a spiral wound gasket?

• To protect the gasket from heat

• To center the gasket

• To provide compressibility

• To create high integrity sealing

Which type of gasket is suitable for high temperature and pressure applications?

• Metallic gasket

• Ring joint gasket

• Semi-metallic gasket

• Nonmetallic gasket

What is the hardness requirement for the metal used in metallic gaskets compared to flange faces?

• Softer than flange faces

• Equal hardness

• Harder than flange faces

• No specific hardness requirement

Which type of ring joint gasket has a higher sealing efficiency?

• Octagonal cross-section

• Rectangular cross-section

• Circular cross-section

• Oval cross-section

What materials are nonmetallic gaskets typically manufactured from?

• Metal

• Graphite only

• Aramid fiber, glass fiber, elastomer, etc.

• Minerals only

What is the general limitation of nonmetallic gaskets in terms of fluid pressure applications?

• Not suitable for any fluid pressure applications

• Limited to low pressure applications

• Limited to high pressure applications

• Limited to medium pressure applications

What is the main advantage of using semi-metallic gaskets in high duty applications?

• Low cost

• High compressibility

• High strength and resilience

• High temperature resistance
