To become a pipefitter, you'll usually need a high school diploma and a 4- or 5-year apprenticeship, with about 2,000 hours of paid on-the-job training each year plus technical instruction. Some US states license pipefitters. In Canada the trade is Steamfitter/Pipefitter, a Red Seal trade with a national standard.
Pipefitters lay out, assemble, fabricate and repair the piping that carries water, steam, gases, chemicals and fuel in heating, cooling and industrial systems. It's close to plumbing but often more industrial, and welding is a big part of it. Here's how to get in, using the US Bureau of Labor Statistics (BLS) handbook and Canada's Red Seal Program, both read in October 2026.

| Training | 4- or 5-year apprenticeship, about 2,000 paid hours a year | Apprenticeship, with the Red Seal standard as the national benchmark |
| Exam | Some states license pipefitters; gas work may need a special licence | The Red Seal exam, based on the national standard |
| Standard | Set locally | The Red Seal Occupational Standard, recognized by the Canadian Council of Directors of Apprenticeship |
How to become a pipefitter in the US
- Finish high school. Maths and science help, because apprentices study mathematics, applied physics and chemistry.
- Consider a vocational course. BLS says vocational-technical schools teach pipe system design, safety and tool use, and some pipefitter apprenticeships require their welding courses.
- Join an apprenticeship. Unions, trade associations and businesses run them. Some people start as helpers or take a pre-apprenticeship first.
- Learn on the job and in class. Expect about 2,000 hours of paid on-the-job training a year, plus technical instruction in safety, codes and blueprint reading.
- Get licensed if your state requires it. Licensing typically needs an exam, work experience or both, and gas line work may need a special licence.
Pipefitter vs plumber
BLS groups the two jobs together and they share the same apprenticeship model, but the Red Seal profile describes pipefitting as work on equipment and piping that carries water, steam, fluids, gases, chemicals and fuel in heating, cooling, lubricating and process piping systems, across sectors from pipelines to pulp and paper. If plumbing is closer to what you want, my guide on how to become a plumber covers that path.
The Red Seal route in Canada
In Canada, Steamfitter/Pipefitter is the trade's official Red Seal title, approved by the Canadian Council of Directors of Apprenticeship. The Red Seal Occupational Standard describes all the trade's activities, skills and knowledge as it's practised across Canada, and the Red Seal exam is based on it.
The Red Seal trade profile says steamfitters/pipefitters work in a long list of sectors, including:
- pipelines, natural gas and inland and offshore oil and gas
- nuclear energy, mining and petrochemical plants
- shipbuilding, automotive and pulp and paper
- renewable energy
- residential, commercial and institutional buildings
With experience, the profile says you can move up to supervisor, contractor, owner, superintendent or instructor. The Red Seal standard is a national benchmark, so check the apprenticeship hours and exam booking rules with the apprenticeship office in your province or territory.
The catch: safety records win work
Here's a line from the Red Seal trade profile that surprised me. It says safety certifications and records can be the difference between getting a job and not being able to bid for work. It also notes more demanding working-at-heights training and better fall restraint systems.
So the tickets you collect during your apprenticeship aren't just box-ticking. They decide which sites you can work on. The profile also points to more 3D scanning, laser layout, robotic layout stations and prefabrication, which means digital skills matter more than they used to.
What pipefitters earn in the US
As of October 2026, BLS gives a median annual wage of $63,800 for plumbers, pipefitters and steamfitters in May 2025. Government employers paid the most of the top industries at $71,660, ahead of manufacturing at $65,770. Plumbing, heating and air-conditioning contractors employ 65% of these workers. Apprentices earn less, but pay rises as they learn.
BLS projects jobs in the group to grow 7% from 2025 to 2035, with about 42,000 openings a year.
What the work is like
BLS says fitters lift heavy materials, climb ladders and work in tight spaces, and some outdoor work in all weather is normal. The Red Seal profile adds that the work is often at heights and that the systems you're working on may carry dangerous substances at high pressure. It's not a desk job, and you'll feel it at the end of a shift.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
You'll also need to keep up with codes. The Red Seal profile says fitters must stay current on a large number of regulations, and that safety, health and environmental rules keep getting stricter. If you like a trade where you're always learning something new, that's a plus.
Skills that help
- welding, cutting, threading, soldering and brazing
- reading drawings, specifications and codes
- mechanical aptitude and manual dexterity
- maths for layout and measuring
- comfort working at heights and in tight spaces
Welding runs through the whole trade, so my guide on how to become a welder is a useful companion.
My verdict
Becoming a pipefitter means a 4- or 5-year paid apprenticeship, and in Canada a Red Seal trade with a national standard behind it. Pick up welding early, collect every safety ticket you can, and check whether your state or province needs a separate licence for gas or pressure work.
