What is the purpose of a flange spreader (or flange jack) in pipefitting work?
Answer: To safely separate stuck flanges for gasket replacement without damaging the mating faces
A flange spreader is wedged between flanges and expanded mechanically or hydraulically to safely push them apart for gasket access without damaging seating surfaces.
A pipe laser level is most useful during which phase of a steamfitting project?
Answer: Establishing grade and elevation for long pipe runs
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.
What distinguishes a reciprocating saw from a jigsaw when cutting pipe in the field?
Answer: A reciprocating saw blade moves in-line with the tool body, allowing access in tight spaces
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.
A boiler feed pump is classified as what type of pump in a steam system?
Answer: Centrifugal pump
Boiler feed pumps are typically multi-stage centrifugal pumps capable of developing the high discharge pressure needed to force water into a pressurized boiler.
Which type of valve is best suited for throttling steam flow to regulate process temperature?
Answer: Globe valve
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.
A T-drill (hole-cutting drill) is used to create a branch outlet in an existing pipe because it:
Answer: Cuts a precise circular hole and forms a collar that eliminates the need for a welded tee fitting
A T-drill cuts and extrudes a collar from the pipe wall itself, creating an integrally reinforced branch opening that can be directly brazed or welded.
What is the purpose of a pipe-freezing kit in steamfitting maintenance work?
Answer: To create an ice plug inside a water pipe to isolate a section without draining the entire system
A pipe-freezing kit circulates CO2 or liquid nitrogen around the pipe exterior, freezing water inside to form a solid plug that temporarily stops flow for repair work.
