Steamfitter Equipment and Tools Knowledge 4

Question 1

What is the purpose of a flange spreader (or flange jack) in pipefitting work?

Accepted Answer

To safely separate stuck flanges for gasket replacement without damaging the mating faces

Answer

A flange spreader is wedged between flanges and expanded mechanically or hydraulically to safely push them apart for gasket access without damaging seating surfaces.

Question 2

A pipe laser level is most useful during which phase of a steamfitting project?

Accepted Answer

Establishing grade and elevation for long pipe runs

Answer

A pipe laser projects a reference beam along the intended pipe path, allowing installers to set hangers and supports at correct elevation and grade over long runs.

Question 3

What distinguishes a reciprocating saw from a jigsaw when cutting pipe in the field?

Accepted Answer

A reciprocating saw blade moves in-line with the tool body, allowing access in tight spaces

Answer

The reciprocating saw's blade extends straight from the body and plunges into confined spaces, making it ideal for cutting pipe in walls or close to structures.

Question 4

A boiler feed pump is classified as what type of pump in a steam system?

Accepted Answer

Centrifugal pump

Answer

Boiler feed pumps are typically multi-stage centrifugal pumps capable of developing the high discharge pressure needed to force water into a pressurized boiler.

Question 5

Which type of valve is best suited for throttling steam flow to regulate process temperature?

Accepted Answer

Globe valve

Answer

A globe valve's disc moves perpendicular to flow and provides fine throttling control; gate and ball valves are designed for full open/closed service, not regulation.
