Which Path Are You On?
Apprentice writing the IP exam
You have finished your technical training and are booked to write the Interprovincial (IP) exam. Use our 5 full-length tests to pace yourself, find weak areas, and walk in ready.
Trade Qualifier / Challenger
You have around 9,000 hours of documented work experience but did not go through the apprenticeship schooling. You plan to challenge the Red Seal exam through your provincial Trade Equivalency Assessment. Our book covers the full NOA so you can close the gaps before exam day.
Rewriting after a previous attempt
If your last attempt did not go the way you wanted, use our detailed answer explanations to fix the knowledge gaps, not just memorize answers. Every question in the book has a written explanation.

1)What does the “70” in the AWS electrode classification E7018 mean?
A. 1.000
B. 1.414
C. 1.732
D. 2.000
Answer: B
Explanation:
For a 45 degree offset, the travel (the hypotenuse) equals the offset multiplied by 1.414. This constant is the square root of 2 and comes from the geometry of the 45-45-90 right triangle. The Red Seal formula sheet lists this value. For example, a 12 inch offset gives a travel of 12 x 1.414 = 16.97 inches.
2)What is the correct grade of a gravity condensate return line?
A. No grade required if the pipe is insulated
B. 1/4 inch rise per foot back toward the boiler
C. 1/4 inch fall per foot in the direction of flow
D. 1/2 inch fall per foot in the direction of flow
Answer: C
Explanation:
Gravity condensate return lines are pitched 1/4 inch per foot (1 in 48) in the direction of flow so condensate drains back to the boiler by gravity. Too little pitch traps condensate and causes water hammer. Too much pitch wastes headroom and is not required. The line must fall toward the return, not rise.
3)A 24-hour air test on a new piping system shows the gauge pressure fluctuating up and down over the test period. What is the most likely cause?
A. A leak at a threaded joint
B. A change in ambient air temperature
C. The test gauge is faulty
D. The line has not been properly purged
Answer: B
Explanation:
During a 24-hour air test, ambient air temperature changes cause the air inside the sealed piping to expand and contract. This shows on the gauge as a pressure rise during the day and a drop overnight. A leak would cause a steady drop, not fluctuation. The Red Seal exam references this exact scenario as a classic critical-thinking question.

Steamfitter / Pipefitter Red Seal Exam — Frequently Asked Questions
What is the Red Seal Steamfitter / Pipefitter exam?
The Red Seal Welder exam is the national trade certification exam for welders in Canada. It tests the knowledge listed in the Welder Red Seal Occupational Standard. When you pass, you receive the Red Seal endorsement on your provincial Certificate of Qualification. This lets you work as a journeyperson welder in any province or territory in Canada without re-certifying.
How many questions are on the Steamfitter / Pipefitter 307A exam?
The exam has 130 multiple-choice questions. Each question has one correct answer out of four options. The questions are split across the seven Major Work Activities in the National Occupational Analysis.
What is the pass mark?
The pass mark is 70%. You need to answer at least 88 out of 125 questions correctly to pass.
How long do I get to write the exam?
You are given 4 hours to write the exam. Most candidates finish before the time is up.
Can I challenge the exam without an apprenticeship?
Yes, in most provinces. You need to show around 6,000 hours of documented work experience in the trade through your provincial apprenticeship body. This route is called Trade Qualifier (TQ) or Trade Equivalency Assessment. Check the rules in your province before you apply.
Can I bring my own notes or textbooks into the exam?
No. The Red Seal exam is a closed-book exam. The only reference materials provided are the formula sheet and the list of acronyms. These are given to you at the exam sitting.
