Pipefitter Aptitude Test: Free Guide and Practice Questions

This page will help you prepare for the Pipefitter test. It includes a detailed guide and free pipefitter test questions and answers. Let’s begin.

What is the Pipefitter Test?

The pipefitter is a screening test used by local unions in the U.S and Canada to screen candidates who want to be accepted to a union apprentice program.
The screening test used by unions in the US is different from those administered to apprenticeship applicants in Canada.

These programs are designed to help candidates become familiar with safety codes and regulations of the field.

As part of the apprenticeship program, apprentices study mathematics, applied physics, and chemistry. In most cases, apprentices enter directly into a program, but others may begin as helpers.

Pipefitter Practice Test With Answers

Pipefitter Math Test Question

1. Please choose the correct answer. If none of the options is the correct answer please choose answer choice e, "N".


4 gallons = ? liters

A. 7.785.

B. 18.

C. 12.

D. 15.14.

E. N.


The correct answer is (D) - 15.14

The conversion needs to be done is as follows:
According to the table
1 gallon = 3.785 liters
Since you are asked for the value of 4 gallons, you will need to multiply both sides of the equation by 4:
=> 1 gallon = 3.785 liters / *4
4 gallons = 4*3.785 liters = 15.14 liters

Pipefitter Mechanical Test Question

2. A canister containing oxygen gas at room temperature (25°C) has a pressure gauge attached. If we connect the canister to an identical but empty canister, what would the pressure gauge show?

A. Pressure increase.

B. Pressure decrease.

C. Pressure unchanged. 

D. Cannot say.


According to the Ideal Gas Law:


Where P =pressure, V = volume, n = number of moles of gas (amount of gas), R = Gas constant, T = temperature.

Since the amount of gas n (in the system) and the temperature T remain unchanged, the right side of the equation remains constant.
In order to maintain the equation, the left side of equation must also remain constant. Thus, since the volume (of the system) has increased the pressure must decrease, respectively, in order that P*V remains constant.
