Utility Gas

Arizona’s gas infrastructure is growing fast, from utility expansions to new RNG grid connections, every weld needs to be done right, whether it’s poly or steel. Earthquake Welding is equipped to provide utility and RNG gas welding support across Phoenix, Tucson, and statewide, ensuring every connection, transition, and station is built to spec.

We’re ready to weld and fuse for a wide range of utility gas services, including:

  • Trench-to-tie-in gas piping for new mains and services

  • Meter set welding and installation for commercial and industrial lines

  • Master meter system installations for multi-unit properties and parks

  • RNG utility grid connections—linking RNG production to the main system

  • Odorization and meter station piping for compliance and control

  • Anode welding and cathodic protection installs for corrosion prevention

  • General utility welding support services for gas companies and contractors

We handle carbon steel welding, HDPE fusion, and poly-to-steel transitions, with certifications to weld to API 1104, ASME B31.8, and utility requirements.

Poly or steel. Welded, fused, and connected to keep Arizona’s gas infrastructure expanding.
