Piping Piping Design and Layout 2

Question 1

What is the purpose of a pipe support guide in a piping system?

Accepted Answer

To allow axial movement while restraining lateral movement

Answer

A pipe guide directs the pipe to move only along its axis (axially) while preventing lateral displacement.

Question 2

Which type of pipe support is used when the load must be transmitted to the structure while allowing vertical movement?

Accepted Answer

Spring hanger

Answer

Spring hangers support pipe weight while allowing controlled vertical movement due to thermal expansion or contraction.

Question 3

What does the term 'dead leg' mean in piping design?

Accepted Answer

A pipe segment with no flow that can accumulate stagnant fluid
