Mechanical room pipe welding

Arizona’s mechanical rooms are the backbone of every large building—moving chilled water, heating loops, and process lines that keep operations running, especially in the brutal summer months. Earthquake Welding is equipped to provide certified welding for mechanical room piping across Phoenix, Tucson, and the entire state.

We weld carbon steel, stainless, and alloy piping for HVAC systems, boiler feeds, chilled water loops, and hydronic piping. Whether it’s a new high-rise in Tempe, a retrofit in central Phoenix, or a mechanical room upgrade for a facility in the East Valley, we weld it to ASME B31.3 standards or project-specific specs.

Every mechanical system relies on proper flow, pressure, and reliability—our welds make sure the piping delivers on all three.
