RNG gas line installation and fusion welding

As RNG facilities gain ground across Arizona, connecting them to the utility grid takes more than basic piping—it takes a crew that can handle gas line installation, poly fusion, and certified welding to spec. That’s the work we’re built for.

At Earthquake Welding, we provide RNG gas line installation and fusion welding services statewide—from poly fusion on facility piping to steel welding for utility tie-ins. Whether the project calls for butt fusion, electrofusion, or poly-to-steel transitions, we’re equipped and certified to do it right, following API 1104, ASME B31.8, and utility requirements.

We’re ready to support RNG developers building the infrastructure Arizona needs—fused, welded, tested, and grid-ready.

When Arizona’s RNG projects need to connect, we’re ready to weld and fuse that connection into place.
