Based in Northern California, Local Union 228 trains and represents qualified journeymen and apprentices of the plumbing, pipefitting, and HVACR service industry. 

Local Union 228 steamfitters/pipefitters layout, fabricate, assemble, install, maintain, and repair piping systems that transport all types of fluids, slurries and gas in the residential, commercial, and industrial sectors. We are the only trade to specialize in planning, design, and installation of low and high pressure steam systems. Our members work in such diverse fields as oil refineries, paper mills, nuclear power plants, and manufacturing plants. They install medical gas lines in hospitals, and high-purity process piping for semiconductor, biotechnology, and pharmaceutical manufacturing. Local Union 228 welders work in every area of the construction industry where metals and alloys are joined.

Their work includes installation, maintenance, and repair of all types of piping systems, as well as join structural steel brackets and supports for such systems. Whether it is an oil refinery, power generating plant, oil pipeline, or medical gas lines in a hospital, the highly skilled welders and pipefitters of Local Union 228 have been committed to excellence for more than a century. Once Local Union 228 pipefitters and welders complete their five-year apprenticeship, they become journeymen in their respective fields. However, their education continues; they train and pursue necessary certifications for specialized areas such as welding, medical gas installation, industrial rigging, and crane signalman.
