GPT Tools & Equipment Operation 2

Question 1

Which tool is used to cut steel gas pipe to a precise length in the field?

Accepted Answer

Pipe cutter (wheel-type)

Answer

A wheel-type pipe cutter produces a clean, square cut on steel pipe and leaves no metal filings inside the pipe.

Question 2

When threading steel gas pipe, what is the correct order of operations?

Accepted Answer

Cut, ream, thread, apply dope

Answer

Cutting first establishes pipe length, reaming removes the internal burr, threading creates the fitting connection, and pipe dope seals the joint.

Question 3

What is the primary purpose of a pipe reamer in gas piping work?

Accepted Answer

Removing the internal burr left by pipe cutting

Answer

The internal burr left after cutting reduces flow area and can trap debris, so reaming restores the full bore before threading.

Question 4

A pipe die set is labeled '3/4 NPT.' What does NPT stand for?

Accepted Answer

National Pipe Thread

Answer

NPT (National Pipe Thread) is the US standard for tapered pipe threads used on gas piping joints to create a pressure-tight seal.

Question 5

Which type of wrench is BEST suited for tightening a large-diameter steel gas pipe fitting in a tight space?

Accepted Answer

Offset pipe wrench

Answer

An offset pipe wrench has its jaws angled from the handle, allowing the technician to grip and turn pipe in confined areas where a straight wrench won't fit.
