RNG facility construction, piping and pressure testing
RNG piping done to spec. Pressure-tested and utility compliant.
Arizona’s shift toward renewable natural gas (RNG) is opening up new ground in energy infrastructure—and when it comes to piping and pressure testing, that’s where we come in. Earthquake Welding provides piping and certified pressure testing services for RNG projects statewide.
This work calls for precise welds on carbon steel, stainless, and HDPE piping systems—from the process lines inside RNG plants to the transmission tie-ins that feed upgraded gas into the grid. We follow API 1104, ASME B31.3/B31.8, and specific utility standards to ensure weld quality, system integrity, and pressure ratings are all dialed in.
Pressure testing is coordinated with every weld phase, confirming every joint is up to the task before gas ever moves downstream.
For developers building RNG infrastructure in Arizona, we’re equipped to handle the piping scope—welded, tested, and grid-ready.
