✍️ Sample PIPEFITTER Questions & Answers

1. What does a WPS (Welding Procedure Specification) document?

✓ The variables, parameters, and conditions under which welding is to be performed to ensure compliance with the code

A WPS (Welding Procedure Specification) is a written document that specifies the welding variables (process, base metal, filler metal, position, preheat, PWHT, etc.) required to produce a sound weld meeting applicable code requirements.

2. Which document gives a pipefitter the legal authority to open a flanged connection on a live process line?

✓ A line break permit (or equipment opening permit)

A line break permit (also called an equipment opening permit) specifically authorizes opening any connection on a process line that may contain hazardous materials.

3. What information is typically found in the title block of a construction drawing?

✓ Drawing number, revision, scale, company name, date, and drawing title

The title block contains administrative information: drawing number, revision level, scale, company/project name, date, drawn/checked by, and the drawing title.

4. What is the difference between a '2-inch 150# flange' and a '2-inch 600# flange' in terms of their application?

✓ The 600# flange has a higher pressure-temperature rating, larger bolt circle, more bolts, and thicker flange body than the 150# flange of the same nominal size

ASME B16.5 flange Class 150 and Class 600 have different pressure-temperature ratings, physical dimensions, bolt patterns, and bolt sizes. Class 600 flanges are physically larger, heavier, and use more bolts than Class 150 flanges of the same nominal pipe size.

5. What is 'working in extreme cold' protection plan and what conditions require its activation?

✓ A plan activated when temperature and wind chill create risk of hypothermia or frostbite, requiring warm-up breaks, buddy systems, protective clothing, and training to recognize cold illness symptoms

Cold weather protection plans address hypothermia and frostbite risk using warm-up breaks, layered clothing, buddy systems, and worker training — activated based on temperature and wind chill combination.

6. What is the role of a 'piping superintendent' on a large construction project?

✓ Overseeing all piping construction activities on the project — managing multiple foremen, tracking overall schedule, resolving technical issues, and interfacing with owners and engineers

A piping superintendent manages the entire piping construction scope — multiple foremen, overall schedule, budget, owner/engineering interface — a senior leadership role.
