Steamfitter Equipment and Tools Knowledge 3

Question 1

What is the function of a come-along (lever hoist) when installing heavy pipe sections overhead?

Accepted Answer

Providing mechanical advantage to lift or pull pipe into position

Answer

A come-along uses a ratchet-and-chain mechanism to multiply pulling force, allowing workers to lift or shift heavy pipe into alignment with limited effort.

Question 2

A pipe saddle support is installed to:

Accepted Answer

Distribute the pipe's weight over a broader bearing surface and prevent point loading

Answer

Saddle supports cradle the pipe's bottom arc and spread load over a larger area, preventing deformation at the contact point.

Question 3

What tool is used to cut cast-iron soil pipe without using a saw?

Accepted Answer

Snap cutter (soil-pipe cutter)

Answer

A snap cutter uses hardened cutting wheels tightened around the circumference; scored evenly, the pipe snaps cleanly with no sparks or dust.

Question 4

In steam piping, expansion loops are formed using pipe bends rather than fittings because:

Accepted Answer

Bends have lower flow resistance and no threaded joints that could leak under thermal cycling

Answer

Smooth bends eliminate threaded or welded joints within the loop and offer less flow restriction, reducing stress concentrations during repeated thermal expansion.

Question 5

A pipe wrap-around (contour marker) tool is used to:

Accepted Answer

Scribe a straight cut line around the pipe circumference

Answer

A wrap-around is a flexible strip with a straight edge that wraps around the pipe OD and allows scribing a square cut line on any pipe diameter.
