Plumbers, pipefitters, and steamfitters work in factories, homes, businesses, and other places where there are pipes and related systems. Plumbers are often on call for emergencies, so evening and weekend work is common.
Most plumbers, pipefitters, and steamfitters learn on the job through an apprenticeship. Some attend a vocational-technical school before receiving on-the-job training. Most states require plumbers to be licensed.
About 42,600 openings for plumbers, pipefitters, and steamfitters are projected each year, on average, over the decade. Many of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire.
Although plumbers, pipefitters, and steamfitters have distinct responsibilities, they often have similar duties. For example, they all install pipes and fittings that carry water, gas, and other fluids and substances. They determine the necessary materials for a job, connect pipes, and test pressure to ensure that a pipe system is airtight and watertight. Their tools include drills, saws, welding torches, press fitting tools, and drain cleaning tools.
Plumbers, pipefitters, and steamfitters may use different materials and construction techniques, depending on the project. For example, residential water systems use copper, steel, and plastic pipe that one or two plumbers install. Industrial plant water systems, in contrast, are made of large steel pipes that usually take a crew of pipefitters to install.
Pipefitters and steamfitters, sometimes simply called fitters, install and maintain pipes that may carry chemicals, acids, and gases. These pipes are mostly in manufacturing, commercial, and industrial settings. Fitters install and repair pipe systems in power plants, as well as heating and cooling systems in large office buildings. Steamfitters specialize in systems that are designed for the flow of liquids or gases at high pressure. Other fitters may specialize as gasfitters or sprinklerfitters.
Plumbers, pipefitters, and steamfitters work in factories, homes, businesses, and other places where there are pipes and related systems. Plumbers and fitters lift heavy materials, climb ladders, and work in tight spaces. Some plumbers travel to worksites every day. Outdoor work, in all types of weather, may be required.
Most plumbers, pipefitters, and steamfitters work full time, including nights and weekends. They are often on call to handle emergencies. Self-employed plumbers may be able to set their own schedules.
A high school diploma or equivalent is typically required to become a plumber, pipefitter, or steamfitter. Vocational-technical schools offer courses in pipe system design, safety, and tool use. They also offer welding courses that are required by some pipefitter and steamfitter apprenticeship training programs.
Most plumbers, pipefitters, and steamfitters learn their trade through a 4- or 5-year apprenticeship. Apprentices typically receive 2,000 hours of paid on-the-job training, as well as some technical instruction, each year. Technical instruction includes safety, local plumbing codes and regulations, and blueprint reading. Apprentices also study mathematics, applied physics, and chemistry. Apprenticeship programs are sponsored by unions, trade associations, and businesses. Most apprentices enter a program directly, but some start out as helpers or complete a pre-apprenticeship training programs in plumbing and other trades.
Most states and some localities require plumbers to be licensed. Although licensing requirements vary, states and localities often require workers to have 2 to 5 years of experience and to pass an exam that shows their knowledge of the trade before allowing plumbers to work independently.
After completing an apprenticeship and becoming licensed at the journey level, plumbers may advance to become a master plumber, supervisor, or project manager. Some plumbers choose to start their own business as an independent contractor, which may require additional licensing.
Most plumbers, pipefitters, and steamfitters work full time, including nights and weekends. Plumbers are often on call to handle emergencies. Self-employed plumbers may be able to set their own schedules.
Demand for plumbers will stem from new construction and from the need to maintain and repair plumbing systems in existing residences and other buildings. Employment of sprinklerfitters is expected to increase as states continue to adopt changes to building codes that require the use of fire suppression systems.
The Occupational Employment and Wage Statistics (OEWS) program produces employment and wage estimates annually for over 800 occupations. These estimates are available for the nation as a whole, for individual states, and for metropolitan and nonmetropolitan areas. The link(s) below go to OEWS data maps for employment and wages by state and area.
CareerOneStop includes hundreds of occupational profiles with data available by state and metro area. There are links in the left-hand side menu to compare occupational employment by state and occupational wages by local area or metro area. There is also a salary info tool to search for wages by zip code.
The What They Do tab describes the typical duties and responsibilities of workers in the occupation, including what tools and equipment they use and how closely they are supervised. This tab also covers different types of occupational specialties.
The Work Environment tab includes the number of jobs held in the occupation and describes the workplace, the level of physical activity expected, and typical hours worked. It may also discuss the major industries that employed the occupation. This tab may also describe opportunities for part-time work, the amount and type of travel required, any safety equipment that is used, and the risk of injury that workers may face.
The How to Become One tab describes how to prepare for a job in the occupation. This tab can include information on education, training, work experience, licensing and certification, and important qualities that are required or helpful for entering or working in the occupation.
The State and Area Data tab provides links to state and area occupational data from the Occupational Employment and Wage Statistics (OEWS) program, state projections data from Projections Central, and occupational information from the Department of Labor's CareerOneStop.
The Job Outlook tab describes the factors that affect employment growth or decline in the occupation, and in some instances, describes the relationship between the number of job seekers and the number of job openings.
The More Information tab provides the Internet addresses of associations, government agencies, unions, and other organizations that can provide additional information on the occupation. This tab also includes links to relevant occupational information from the Occupational Information Network (O*NET).
The wage at which half of the workers in the occupation earned more than that amount and half earned less. Median wage data are from the BLS Occupational Employment and Wage Statistics survey. In May 2023, the median annual wage for all workers was $48,060.
When I first began I already knew a lot about this, and after a while I knew nothing. RE: Calculating a rolling offset in a pipe configuration? TBP (Mechanical)5 Jan 04 17:21That is indeed the mathematically correct method. However, you're left with finding the square root of the right side of the equation. If you're in an office you can open a drawer or briefcase and pull out a calculator. Pocket calculators tend to have pretty short lifespans in pipe trades pockets or tool boxes. I can't think of a fitter or plumber (or anyone else, for that matter) who can calculate a square root without one. If you've got a tape measure & a piece of soapstone or a pencil (and how can you NOT, if you're running pipe), you can determine the centre-to-centre dimension for any offset using the corner of the railing on the manlift, the lid on the job box, or an inside corner of the room. A framing square makes it go a little faster. Simple is good. RE: Calculating a rolling offset in a pipe configuration? pipewelder1999 (Industrial)5 Jan 04 17:54I think
offset=sqrt(set^2+roll^2)
Travel=Offset x =1/SIN(FittingAngle)
Run=offset*1/tan(fittingAngle)
Takeout For Fittings=Tan(fittingangle/2)x NPS
I previously had a program in a HP 32SII calculator that I used while I watched my fitter unload his square and pipefitters handbook. In my opinion it was much faster than the squares etc but the batteries never failed on his squares !

RE: Calculating a rolling offset in a pipe configuration? TBP (Mechanical)5 Jan 04 22:52Have you had your HP 32SII drop out of your pocket when you're up on a 12' step ladder, had it bounce twice off the concrete floor, land in a puddle, and had it still functional? I bet not :) I know for a fact that Stanley "Contractor Grade" tape measures will. If it won't survive a landing like that, it's not much good on a job-site. Simple is good. Simple and tough is better. RE: Calculating a rolling offset in a pipe configuration? pipewelder1999 (Industrial)6 Jan 04 07:10TBP
No never a fall from that height though I have dropped a many tapes from that height or more.
Actually the face has seperated from the plastic case at the top. The LCD has quite a bit of weld spatter. And it has seen numerous falls from when I bend over. Still functions except when the batteries are dead.
In the past 5 or 6 years I have bought at least 6 tapes due to bent hooks broken tapes or failed return springs. I still have the same calculator and a spare I thought I would need long before now.
After deciding the amount of rise and roll I need, it takes 25 to 30 seconds to get the c to c travel and takeout for the fittings. Has your tape measure and square ever done that ? I do have a Pipe Trades handbook along with all of IPT's other handbooks. I value them much more than a calculator. Howevr the amount of time it took me to learn how to program the calculator was small compared to the hours lost waiting for a fitter.
Take the task of calculating the takeout for a 36 degree elbow. Is that done with a tape measure ,is it calculated, or is it looked up ? From the time I know thats what I need using any calculator with trig functions it takes maybe 5 seconds. It takes at least that long to lookup the tangent of 36 degrees if you had your handbook already out. If there is a faster way to do this without a calculator, let me know.
In the construction trades I'm sure your view is held by most and will continue to be that way for some time. The most efficient way to do a job is always the most efficient way. That method may not be efficient for all.
Thanks and Have a good day
