Pipe Fitter

A pipe fitter is a trades person who installs, assembles, fabricates, maintains and repairs mechanical piping systems. Pipe fitters usually begin as helpers or apprentices. Journeyman pipe fitters deal with industrial/commercial/marine piping and heating/cooling systems.

What is a Pipe Fitter?

Also known as: Steamfitter, Licensed Pipe fitter, Journeyman Pipe fitter

A pipe fitter, also known as a steamfitter, is a tradesman trained in the art of organizing, assembling, creating and maintaining mechanical piping systems that must withstand high pressure. These types of systems are usually industrial and include heating and cooling systems and involve work with steam, ventilation, hydraulics, chemicals and fuel.

This occupation is often overlooked and sometimes confused with the occupation of a plumber. However, a steamfitter and a plumber differ in the fact that plumbers work with low-pressure piping systems, such as utility systems. Pipe fitters work more in welding and not very much in the fields of water or water sanitation.

What does a Pipe Fitter do?

Steamfitters work with metals such as carbon and stainless steel, as well as other alloy metals. These metals are shaped through welding and bending to fit specifications for industrial use. Fitters are involved in the process from planning to installation and will work with tools such as levels, grinders, dies and welding torches.

A steamfitter will typically create a sketch or a blueprint of a pipe installation or be called upon to interpret existing blueprints. During this process, the fitter is also responsible for selecting the type and size of the pipe, as well as determining other related materials and equipment that are required for the project. From there, the fitter will manipulate metal to form the pipes to according to the specifications.

Types of manipulation that a fitter will perform on pipes and metal include but are not limited to:









When the pipes are ready, the fitter will transport them on location and install them. The installation is very important and workers must take care to avoid obstructions and also interference with work currently going on in the building. After installation is complete, several tests are performed to check for any leaks, support issues and performance against high-pressure environments. Adjustments are made to ensure the system will run smoothly until the next maintenance which is usually performed by a steamfitter. They can also be called upon to repair existing systems or replace pipes as needed.

What is the workplace of a Pipe Fitter like?

Many different employers have a need for pipe fitters. Employers include utility companies, gas plants, hospitals, chemical plants, oil refineries, building companies, heating and air ventilation companies and construction firms. Work is done both indoors and outdoors, depending on the project itself. Pipe fitters may spend some time at the installation location but will spend far more time manipulating and creating the pipes than at the actual installation location.

There is a risk of injury in this occupation, as fitters work with power tools and heavy equipment frequently. Working conditions may vary but this occupation involves a lot of standing and sometimes working in tight quarters for long periods of time. There is also occasional exposure to potentially harmful gases. In this situation workers are asked to wear a respirator or mask. Work hours are often extended beyond typical office hours, calling for as long as a 12-hour workday period. Pipe fitters often receive emergency calls because the systems that they work with are often essential for the building to properly function.
