Training Center

No other organization serves the training needs of the piping industry like the United Association.  For over a century, the UA has been training the most highly-qualified workers in the United States and Canada.

Over the past several decades, the United Association's training programs have produced a stable, skilled workforce responsible for building and maintaining piping systems in the various industrial and residential facilities that make up the North American landscape.

No one can match the commitment or investment.  The UA spends over $100 million annually on training programs efforts involving approximately 100,000 journeymen and apprentices in over 400 local training facilities at any given time.

If the United Association wanted to select the area which best reflects this commitment to the training and excellence produced, it could well look to state of Pennsylvania.  Thanks in part to our relationship with the Mechanical Contractors Association, Steamfitters local 420 offers state of the art training year round.

We train apprentices and journeyworkers in many skills including: Pipe Fabrication, Pipe Welding, Orbital Tube Welding, Medical Gas Systems, Process Safety Management, Instrumentation /Calibration, Heating/Air Conditioning/Refrigeration, Rigging, Pipe Drafting, OSHA Safety, Computer Aided Drafting, Computerized Pipe Design in 3D, Primavera (Computer Software) Planning and Scheduling, and more.

In addition to our five-year apprenticeship programs, we offer continuing education opportunity that includes journeymen training and certification, as well as associate degree programs.
