What a pipefitter actually does

Pipefitters install, assemble, fabricate, maintain, and repair piping systems that carry steam, chemicals, fuel, and other process fluids in industrial and commercial buildings. The job is hands-on, technical, and safety-critical; it is not just “turning wrenches.” BLS groups pipefitters and steamfitters with related pipefitting work in the broader construction trades and notes typical work in power plants, refineries, factories, and large mechanical systems.

Pay, demand, and why the trade is worth looking at

For pipefitters and steamfitters, BLS reports a median annual wage of $61,060 in May 2024. BLS projects 1% employment growth from 2024 to 2034, but still expects about 11,300 openings per year from growth and replacement needs. The real opportunity is not explosive growth; it is steady demand plus retirements and turnover.

Union path: the structured route

The union route usually means applying to a United Association (UA) apprenticeship through a local joint apprenticeship training committee. UA training is built around paid on-the-job learning plus classroom instruction, and apprenticeship is the standard entry point for many union pipefitters. The tradeoff is simple: harder entry, stronger structure. Expect aptitude testing, interviews, drug screening in some locals, and a competitive selection process.

  • Best for: people who want formal training, clear wage steps, benefits, and a pension.
  • Typical reality: more standardized training and credentials, but less flexibility on where and when you work.
  • Hard truth: you may wait for an opening. Good locals are competitive.

Non-union path: the faster entry route

Non-union pipefitting usually means getting hired by an open-shop mechanical contractor and learning on the job, sometimes with a company apprenticeship or a community-college program layered on top. This path can get you into the field faster, but training quality, wage progression, and benefits vary a lot by employer.

  • Best for: people who need to start earning quickly, want more employer-to-employer flexibility, or live where union density is low.
  • Typical reality: you may start sooner, but you have to be more careful about the quality of the shop, the foremen, and the training.
  • Hard truth: “non-union” is not a training model; it is a labor model. Some shops are excellent, some are weak.

Safety and credentials matter either way

OSHA’s construction standards apply regardless of union status, and pipefitting work routinely involves hot work, confined spaces, welding, cutting, rigging, and fall hazards. If you are serious, build the baseline early: OSHA safety awareness, blueprint reading, math, tool use, and welding basics. The better your safety record and technical foundation, the faster you move.

How to choose between union and non-union

Choose union if you want the strongest formal training, negotiated wage scales, and long-term benefits. Choose non-union if you want faster entry, more flexibility, and are willing to judge each employer on its own merits. Either way, the winning move is the same: get into a real apprenticeship or a real mechanical contractor, show up early, learn code and prints, and become useful fast.

  • Union advantage: standardized training, portable credentials, benefits, pension.
  • Non-union advantage: easier entry, faster hiring, more shop-to-shop flexibility.
  • Best first step: apply to UA locals and open-shop mechanical contractors at the same time so you do not sit on the sidelines waiting.

Bottom line

If you want a long career in pipefitting, do not chase the label; chase the training, the work quality, and the safety culture. The union path is usually the better structured road, but a good non-union shop can also launch a solid career if you are disciplined and selective.
