ASME B31.3 and B31.8 welding

When it comes to high-pressure gas, fuel, and industrial piping systems, welding to ASME code isn’t just smart—it’s required. Earthquake Welding provides code-compliant welds certified to ASME B31.3 (process piping) and ASME B31.8 (gas transmission and distribution) for work throughout Arizona.

Whether it's mechanical room piping, fuel lines at a terminal, or a high-pressure gas install on a utility corridor, these codes govern how the welds are prepped, performed, and inspected. We bring the procedures, equipment, and crew certifications to get it done right—whether it’s new construction, a tie-in, or a retrofit under pressure.

We work by the book, but we also work fast—delivering the level of quality Arizona contractors, developers, and facility owners expect.
