Local Union 455

What Local Union 455 does

Local Union 455 (legal name: Steamfitters Pipefitters Local 455) is a non-profit labor union chartered on November 5, 1904 under the United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry. Headquartered at 1301 L Orient Street in Saint Paul, Minnesota, the union represents more than 1,500 certified steamfitters and pipefitters across a 22-county jurisdiction in central Minnesota, including the Twin Cities. It is one of only 13 'straight-line' locals in the United States whose membership consists exclusively of steamfitters and pipefitters (rather than mixed trades). Members hold city licenses for steam, refrigeration, gas, and oil work, plus high-pressure steam credentials, and serve industrial, commercial, institutional, and residential end-markets.

The union's core offerings include collective bargaining representation, a five-year registered apprenticeship program, job placement through 60+ signatory contractors, and a 100,000-square-foot training and certification center that opened in August 2015. Training covers high- and low-pressure steam and hot water systems, refrigeration, heating, gas and oil piping, pneumatic and electronic controls, air conditioning, instrumentation, and valve repair across 50+ trade segments ranging from welding to rigging. The union operates recruitment pipelines through technical college partnerships (St. Paul College pipefitting program; Century College HVACR program) and supports members and their families through multiple scholarship funds.

The business model is funded primarily by recurring monthly member dues (subscription-like) and secondary income from apprentice-related training fees, with additional ancillary revenue from member benefits administration. Members are placed with signatory contractors who serve named anchor end-clients including Koch Oil Refinery, Northern States Power/Xcel Energy (Sherco, High Bridge, Prairie Island Nuclear, Allen S. King, District Energy biomass), Harris Companies, Johnson Controls, University of Minnesota, Saint Paul School District, and Metropolitan Council. Governance is by elected officers (Business Manager, President, Vice President, Financial Secretary-Treasurer, Recording Secretary) and an elected Executive, Finance, and Examining Board, with affiliation to the United Association, Minnesota AFL-CIO, and St. Paul Regional Labor Federation.
