Sievert Group Interview Questions and Answers

A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.

• Pressure vessels are used in various industries such as oil and gas, chemical, pharmaceutical, and food processing.

• They are designed to withstand high pressures and are typically cylindrical or spherical in shape.

• Examples include boilers, storage tanks, and heat exchangers.

Types of exchangers include shell and tube, plate, and air-cooled exchangers.

• Shell and tube exchangers are most commonly used in industrial applications.

• Plate exchangers are compact and efficient, often used in HVAC systems.

• Air-cooled exchangers are used when water is scarce or when process fluid must be kept separate from cooling water.

Valves are mechanical devices used to control the flow of fluids or gases in a system.

• Valves can be opened or closed to allow or stop the flow of fluids or gases.

• They are commonly used in pipelines, plumbing systems, and industrial processes.

• Types of valves include gate valves, ball valves, butterfly valves, and globe valves.

Types of welding include MIG, TIG, stick, and flux-cored welding.

• MIG welding uses a wire electrode and shielding gas to join metals together.

• TIG welding uses a tungsten electrode and inert gas to create a strong weld.

• Stick welding, also known as shielded metal arc welding, uses a flux-coated electrode.

• Flux-cored welding uses a tubular wire filled with flux to protect the weld from contamination.
