Pipe welding for gas lines

Arizona’s growth has made natural gas more essential than ever—from commercial builds in Phoenix to new utility installs across the Valley. At Earthquake Welding, we provide certified gas line welding that’s built for pressure, safety, and long-term reliability.

We handle everything from live gas tie-ins and HDPE fusion to meter sets, regulators, and polyurethane gas lines for commercial service. Every weld meets API 1104 and ASME B31.8 specs, and we back it with 20+ years of field experience right here in Arizona.

Whether you’re replacing a damaged section or laying in a full run, we’re the crew local GCs and utilities trust when code compliance and speed matter.
