Piping Engineering 2

Question 1

What is the primary purpose of a pipe stress analysis in piping engineering?

Accepted Answer

To evaluate forces and moments on piping systems under load

Answer

Pipe stress analysis evaluates forces, moments, and displacements in piping systems caused by pressure, temperature, weight, and other loads.

Question 2

Which piping code primarily governs process piping in industrial plants in the US?

Accepted Answer

ASME B31.3

Answer

ASME B31.3 covers process piping used in petroleum refineries, chemical plants, and similar facilities.

Question 3

What does the term 'schedule' refer to when specifying pipe?

Accepted Answer

The pipe wall thickness designation

Answer

Pipe schedule is a dimensionless designator that determines the wall thickness of a pipe for a given nominal pipe size.

Question 4

What is cavitation in a piping system?

Accepted Answer

Formation and collapse of vapor bubbles due to pressure drop below vapor pressure

Answer

Cavitation occurs when local pressure drops below the fluid's vapor pressure, forming bubbles that collapse violently and damage equipment.

Question 5

Which type of valve provides the best throttling control in a piping system?

Accepted Answer

Globe valve

Answer

Globe valves are designed for throttling service because their disc movement perpendicular to the seat allows fine flow control.
