PURE Interview Questions and Answers

Piping refers to the system of pipes used to transport fluids within a facility, while a pipeline is a long-distance transportation system for fluids or gases.

• Piping is typically used within a facility or plant, while pipelines are used for long-distance transportation.

• Piping systems are usually smaller in diameter and operate at lower pressures compared to pipelines.

• Piping systems are often designed for specific processes within a facility, while pipelines are designed for c...read more

There are several types of primary supports in piping engineering.

• Primary supports are used to anchor and support the weight of the piping system.

• Common types of primary supports include pipe shoes, pipe clamps, and hangers.

• Pipe shoes are used to support the weight of the pipe at specific intervals.

• Pipe clamps are used to hold the pipe in place and prevent movement.

• Hangers are used to suspend the pipe from a structure or support beam.

• Other types of primary supports include sp...read more

Nozzle orientation height refers to the vertical distance between the centerline of a nozzle and a reference point.

• Nozzle orientation height is an important parameter in piping engineering.

• It is used to determine the elevation of a nozzle in relation to other components in a piping system.

• The height is measured from a reference point, which is typically a horizontal plane or a specific equipment datum.

• Nozzle orientation height is crucial for proper alignment and installation ...read more

The number of inlet or outlets in a heat exchanger depends on its design and purpose.

• Heat exchangers can have multiple inlet and outlet connections.

• The number of inlets and outlets can vary based on the type and size of the heat exchanger.

• Some heat exchangers may have separate inlets and outlets for different fluids.

• In a shell and tube heat exchanger, there are typically two inlets and two outlets, one for each fluid.

• Plate heat exchangers can have multiple inlets and outlets ...read more

There are several types of supports used in piping engineering.

• Rigid supports: These provide fixed support to the piping system, preventing movement.

• Flexible supports: These allow for movement and absorb thermal expansion and contraction.

• Hanger supports: These are used to suspend the piping system from above.

• Spring supports: These use springs to support the weight of the piping system.

• Snubber supports: These are used to control excessive movement caused by seismic or dynamic ...read more

There are several types of piperacks used in piping engineering.

• Piperacks can be classified based on their design and function.

• Common types include single-tier piperacks, multi-tier piperacks, and modular piperacks.

• Single-tier piperacks are used for smaller piping systems, while multi-tier piperacks are used for larger systems.

• Modular piperacks are pre-fabricated and can be easily assembled on-site.

• Other types include bridge piperacks, cantilever piperacks, and trapeze pipera...read more
