Senior Piping Supervisor Interview Questions and Answers

Two types of ball valves are floating ball valve and trunnion ball valve. Isometrics drawings are 3D representations of piping systems.

• Floating ball valve has a floating ball design that seals against the seat under pressure.

• Trunnion ball valve has a fixed ball design that is supported by trunnion bearings.

• Isometrics drawings are detailed 3D representations of piping systems showing the layout, dimensions, and connections of pipes.

• Isometrics drawings are used in the planning,...read more

Types of compressor drives include electric motor, gas turbine, steam turbine, and diesel engine.

• Electric motor

• Gas turbine

• Steam turbine

• Diesel engine

Wetted parts of valves are the components that come in contact with the fluid being controlled by the valve.

• Wetted parts include the valve body, seat, disc, stem, and any internal components that are in direct contact with the fluid.

• These parts are typically made of materials that are compatible with the fluid to prevent corrosion or contamination.

• Examples of wetted parts materials include stainless steel, brass, bronze, and various types of plastics.

• It is important to consid...read more

Feed nozzles can be located by referring to piping and instrumentation diagrams (P&IDs) and equipment layout drawings.

• Refer to P&IDs to identify the location of feed lines and nozzles

• Consult equipment layout drawings to pinpoint the exact location of feed nozzles on equipment

• Use isometric drawings to visualize the piping layout and locate feed nozzles accurately

Isolation valves are types of valves used to completely stop the flow of fluid in a piping system.

• Isolation valves are typically used to isolate a section of piping for maintenance or repair purposes.

• They are designed to completely stop the flow of fluid when closed.

• Common types of isolation valves include ball valves, gate valves, and butterfly valves.

• Isolation valves are essential for ensuring the safety and efficiency of a piping system.

Regulations valves are valves that are designed and manufactured to meet specific industry standards and regulations.

• Regulations valves are used in various industries such as oil and gas, petrochemical, and pharmaceutical.

• These valves are built to comply with specific codes and standards set by organizations like ASME, API, and ISO.

• They are essential for ensuring safety, efficiency, and compliance with regulatory requirements.

• Examples of regulations valves include gate valves...read more

• Distillation towers

• Cooling towers

• Flare towers

• Fractionation towers

• Reboiler towers
