GVPR Engineers Piping Engineer Interview Questions and Answers

There are several types of gaskets used in piping, including spiral wound, ring joint, and sheet gaskets.

• Spiral wound gaskets are commonly used for high pressure and temperature applications.

• Ring joint gaskets are used in high pressure and high temperature applications, typically in oil and gas industries.

• Sheet gaskets are versatile and come in various materials such as rubber, cork, and graphite.

Suction piping of a pump is the piping system that brings fluid into the pump from the source.

• Suction piping is designed to ensure a smooth flow of fluid into the pump without any air pockets or cavitation.

• The piping should be sized appropriately to prevent excessive pressure drop and maintain efficient pump operation.

• Proper alignment and support of the piping is crucial to prevent stress on the pump and ensure longevi...read more

Eccentric reducers are used in suction lines with flat side up to prevent air pockets and improve flow efficiency.

• Eccentric reducers help in preventing air pockets from forming in the suction line

• Having the flat side up ensures that any trapped air can easily escape

• Improves flow efficiency by reducing turbulence and pressure drop

• Commonly used in applications where smooth flow is critical, such as pump suction lines

Figure 8 is a type of knot commonly used in piping design to secure two ropes or cables together.

• Figure 8 knot is also known as a stopper knot due to its ability to prevent ropes from slipping through holes or other openings.

• It is easy to tie and untie, making it a popular choice for various applications in piping design.

• The figure 8 knot is often used in rock climbing, sailing, and rescue operations for its reliabilit

Control station piping is essential for regulating and monitoring the flow of fluids in a system.

• Control station piping connects various components such as valves, instruments, and equipment to control the flow of fluids.

• Proper design of control station piping ensures efficient operation and safety of the system.

• Consider factors like pressure, temperature, and material compatibility when designing control station pipin...read more

Suction piping of pump is crucial for efficient operation and performance.

• Suction piping should be designed to minimize friction losses and ensure proper flow to the pump.

• Proper sizing and layout of suction piping is essential to prevent cavitation and maintain pump efficiency.

• Consider factors such as pipe diameter, length, bends, and fittings when designing suction piping.

• Use smooth bore pipes, avoid sharp bends, and ...read more
