Natural gas line installation

Arizona isn’t slowing down—natural gas infrastructure is expanding with it. From high-pressure steel mains feeding the Valley to low-pressure poly services running into new builds, Earthquake Welding provides certified natural gas line installation across the state.

We install and weld everything from transmission-grade steel to HDPE and polyurethane piping for commercial, utility, and industrial applications. Whether it’s a steel gas main in Buckeye, a poly service line in Queen Creek, or an LNG-related facility upgrade, our crews are equipped to get it installed, welded, and tested to spec.

We work to API 1104, ASME B31.8, and utility standards—delivering gas lines ready for pressure testing, inspection, and long-term service. As Arizona stretches outward—subdivisions, data centers, LNG infrastructure—it all needs gas. That’s where we come in.
