Exhaust Stacks

Large Diameter, HRSG, Bypass, and Steel Flare Stacks Since 1976

Dixie Southern provides stainless steel fabricated and carbon steel fabricated exhaust stacks that can be delivered anywhere in the world. 

  • Heat recovery steam generator (HRSG) Stacks – These are important components of many power plants as they increase a plant’s overall efficiency and help to minimize the costs of fuel.
  • Cylindrical and square exhaust stacks – To accommodate customers in the power industry who need exhaust stacks, Dixie Southern creates cylindrical or square exhaust stacks at our large fabrication facility.
  • Bypass exhaust stacks – These are alternative stacks used for discharging combustion gases to the atmosphere primarily to avoid severe damage to an air pollution control device or other equipment.
  • Large diameter steel exhaust stacks
  • Over-dimensional and overweight capabilities for steel flare stacks
  • Burn-off oven exhaust stacks
  • Furnace oven exhaust stacks
  • Industrial steel flare stacks for high-temperature systems in many industries
Our custom steel exhaust stacks meet the exacting standards of the American Society of Mechanical Engineers (ASTM STS-1, ASME Section IX) and the American Welding Society (AWS D1.1 and AWS D1.6) as required by our clients.

The Dixie Southern Process

5 Steps to Completion of Your Stacks


We design your large diameter, HRSG, bypass, and steel exhaust stacks to meet standards, as required.


You review our over-dimensional stack design before we begin fabrication.


We utilize cutting-edge engineering and manufacturing processes to ensure your steel exhaust stack meets all safety regulations and your requirements.


Steel exhaust stack fabrications are inspected by our in-house Quality Assurance, Certified Welding Inspectors, and/or third-party inspection as our clients’ specifications may require.


We conduct any customized testing that you may require, then blast, coat, passivate, and ship your stack to your facility anywhere in the continental U.S. or overseas.
