Certified RNG distribution pipeline welding
As renewable natural gas (RNG) expands across Arizona, new distribution pipelines need welds that are built to last and certified to code. Earthquake Welding provides certified welding services for RNG distribution pipelines, ensuring every joint meets the demands of pressure, safety, and regulatory compliance.
We weld carbon steel, stainless, and HDPE pipeline systems, following API 1104, ASME B31.8, and any utility-specific requirements. Whether it’s steel mains feeding into the Phoenix metro grid or poly lines running through Pinal and Maricopa Counties, we’re equipped to handle the welding scope from start to tie-in.
Every weld is qualified, traceable, and ready for inspection—because RNG infrastructure requires the same precision and integrity as any transmission system.
Certified crews. Built for RNG. Ready for the grid.
