Piping Components 4

Question 1

Which component is used to absorb thermal expansion and contraction in piping systems?

Accepted Answer

An expansion joint or expansion loop

Answer

Expansion joints and expansion loops are specifically designed to absorb the movement caused by thermal expansion and contraction in piping.

Question 2

What is a 'weld-o-let' used for in industrial piping?

Accepted Answer

To create a branch connection by welding directly to the run pipe

Answer

A weld-o-let (olet fitting) is welded directly onto the run pipe to create a reinforced branch outlet connection.

Question 3

What is the purpose of a strainer (Y-strainer) in a piping system?

Accepted Answer

To remove solid particles and debris from the fluid stream

Answer

A Y-strainer uses a perforated or mesh screen to filter out solid particles and protect downstream equipment from damage.

Question 4

In which situation would you use an eccentric reducer rather than a concentric reducer?

Accepted Answer

When installing horizontal liquid lines to prevent air pockets or vapor locks

Answer

Eccentric reducers are used in horizontal liquid lines with the flat side up to prevent air pockets, or flat side down to avoid sediment traps.

Question 5

What is a 'flange' in piping, and what is its primary advantage?

Accepted Answer

A flat ring fitting that bolts two pipe sections together, allowing easy disassembly

Answer

A flange is a flat disc-like fitting bolted to another flange to join pipe sections, allowing easy disassembly for maintenance or inspection.
