Process Piping Design & Installation Atlanta, GA

Process Piping Built Right, From the Shop to the Field.

Process piping demands precise design, quality welds, and minimal disruption to facilities that are often still running. Mallory & Evans handles design-build process piping for commercial and industrial clients, from hydronic and chilled water to steam, condensate, and specialty applications. Our in-house shop prefabricates most assemblies off-site, so they arrive ready to install with cleaner welds and less field time.

Engineered Process Piping for Georgia's Most Demanding Facilities

Process Piping From Design Through Commissioning

Mallory & Evans provides process piping installation in Atlanta, GA and surrounding areas. Our team handles HVAC hydronic piping, chilled water systems, steam and condensate systems, process piping, and specialty applications, with the engineering staff, fabrication capabilities, and field experience to execute from design through commissioning. Because the same firm carries a project from the drawing board to startup, the design accounts for how the system will actually be built and serviced, not just how it looks on paper. That continuity is what keeps complex piping projects on budget and on schedule. For owners and general contractors, it means a single accountable point of contact for the entire mechanical piping scope.

An In-House Shop Built for Pipe Fabrication

Our in-house shop specializes in pipe fabrication and installation, prefabricating the majority of assemblies off-site in a controlled environment and then delivering them ready to install. That approach reduces field labor time, improves weld quality and consistency, and minimizes disruption in occupied or operational facilities. We fabricate in a range of materials and pressure classes to match the application, from standard hydronic loops to high-purity and high-pressure process lines, and we coordinate delivery with your construction sequence so crews are never waiting on parts. The result is a cleaner installation with fewer change orders.

Permitting, Inspection, and Compliance Handled

We pull the required permits, coordinate inspections, and document compliance throughout the project, so the system is not only installed correctly but verifiably so. Our field teams test, flush, and commission each system before handover, and we provide the documentation your facility and its inspectors need for the record. Whether the work is part of a new build, an expansion, or a retrofit to a live facility, we plan it to protect ongoing operations. Call (404) 297-1007 for process piping work across Georgia, and we will walk your site to scope the work.
