Carbon steel pipe welding

Carbon steel piping systems in Arizona

From Goodyear warehouse infastructure to East Valley gas line upgrades, carbon steel piping is still the backbone of Arizona’s mechanical and utility infrastructure. At Earthquake Welding, we deliver field-proven carbon steel welds for fuel systems, high-pressure gas, chilled water lines, and everything in between.

Whether it’s a 6" gas main in Glendale, a mechanical retrofit in Tempe, or a vault install out in Buckeye, we show up ready with certified welders, proper fit-up, and full compliance to spec—ASME, API, or utility standard, depending on the job. We’re equipped to work on new construction, retrofits, shutdowns, or section replacements throughout the Valley and beyond.

This is the material most jobs still rely on—and we know how to weld it right the first time.
