Poly gas line welding/fusing for RNG facilities

RNG facilities need more than just process equipment—they need gas lines that are fused, welded, and ready to connect. Earthquake Welding provides poly gas line welding for RNG facilities across Arizona, ensuring every fusion weld is up to spec and every transition holds under pressure.

Whether it’s a poly-to-steel transition feeding a utility tie-in, or an all-poly system moving upgraded gas within the facility, we’ve got it handled. Our crews perform butt fusion, electrofusion, and certified welding on steel interfaces, ensuring your gas lines are leak-free, compliant, and ready for flow.

We weld and fuse to utility standards, API 1104, and ASME B31.8, with full traceability and inspection-ready documentation.
