Pump pad and vault pipe welding

Beneath Arizona’s fuel terminals and utility sites, the real work happens at the pump pads and vaults—and every connection has to be welded to hold under pressure, flow, and time. Earthquake Welding provides certified pipe welding for pump pads and vaults, ensuring critical underground and above-ground systems stay reliable.

We weld carbon steel, stainless, and alloy piping for pump discharge lines, suction headers, manifold connections, and vault piping in fuel facilities, utility infrastructure, and industrial sites. Whether it’s a new pump install in the West Valley, a vault upgrade in Tucson, or a full system modification, we weld to API 1104, ASME B31.3, or specific facility requirements.

These are the welds you don’t see—but they’re the ones that keep product moving.
