Mechanical
Mechanical installation, maintenance, and equipment work that keeps plant systems running — through daily operations and demanding turnarounds.
Keeping plant systems running
Piping is only part of a working plant. Our mechanical crews install, maintain, and overhaul the equipment that piping connects — pumps, exchangers, vessels, and rotating machinery — across Louisiana and Oklahoma's industrial facilities.
ATS holds a National Board "R" Stamp and an ASME "S" Stamp, authorizing us to repair, alter, and fabricate pressure vessels and power boilers to code — capability few mechanical contractors in the region can offer in-house.
We bring the same craft and documentation discipline to mechanical work that we bring to welding: careful setting and alignment, correct gaskets and torque, and clean execution around live operations. That keeps equipment reliable and downtime short.
From routine maintenance to major turnarounds, our teams mobilize fast and work safely to get systems back in service on schedule.
What we handle
Equipment Setting
Rigging, setting, and grouting of pumps, vessels, and skids to foundation and tolerance.
Rotating Equipment
Installation and maintenance of pumps, compressors, and drivers with precision alignment.
Heat Exchangers
Bundle pulls, re-tubing support, and exchanger reassembly during maintenance and turnarounds.
Alignment
Shaft and coupling alignment that protects seals and bearings and extends equipment life.
Bolting & Gaskets
Controlled bolt torque and proper gasket selection for leak-tight, reliable joints.
Turnaround Support
Planned outage crews that hit the schedule and get units back online safely.
Reliability you can schedule around
Mechanical work lives and dies on planning and precision. We stage parts, protect running equipment, and document every step so your systems come back stronger than they went down.
