Industrial ventilation and exhaust ducting is used to remove air, fumes, heat, dust or process exhaust from plant areas and route it toward fans, cyclones, scrubbers, filters, stacks or discharge points.

National Engineers & Steel Fabricators manufactures industrial ventilation ducting and exhaust ducting for plants where airflow stability, duct strength, routing accuracy and maintenance access are important.

Our ducting can support:

• General plant ventilation
• Process area exhaust
• Heat exhaust movement
• Utility area exhaust
• Workshop ventilation
• Equipment exhaust routing
• Industrial air movement
• Process-air extraction

Dust collection ducting is used to transfer dust-laden air from process points to dust collectors, cyclones, filters, scrubbers or other pollution control equipment.

National Engineers & Steel Fabricators fabricates dust extraction ducting with suitable duct geometry, access provision, wear consideration, flange interface and support arrangement based on dust characteristics and airflow duty.

Dust extraction ducting can be used for:

• Powder handling areas

Fume extraction ducting is used to capture and route fumes from welding areas, chemical process areas, heat-treatment zones, process tanks, exhaust hoods or equipment outlets.

National Engineers & Steel Fabricators manufactures fume extraction ducting for industrial systems where corrosion risk, temperature, chemical exposure, access and safe routing must be considered.

Fume extraction ducting may be fabricated in GI, MS, SS or other specified materials depending on fume type, temperature, moisture and corrosion condition.

Process air ducting and utility air ducting are used to route air between process equipment, utility systems, fans, blowers, filters, cyclones, scrubbers and plant equipment.

National Engineers & Steel Fabricators fabricates process-air ducting for custom plant layouts where standard ducting sections may not match equipment interface, routing, support or access requirements.

Our process ducting fabrication can include:

• Fan inlet ducting
• Fan outlet ducting
• Equipment interconnection ducting
• Utility air routing ducting
• Process ventilation ducting
• Duct spools for air handling lines
• Duct transitions for equipment connections
• Duct sections with access and inspection openings

Industrial ducting systems often require multiple fabricated sections to connect equipment across a plant layout. National Engineers & Steel Fabricators manufactures duct spools, elbows, reducers and transitions as per duct layout and interface dimensions.

Common fabricated ducting components include:

• Straight duct spools
• Duct elbows
• Duct bends
• Reducer sections
• Transition sections
• Offset duct sections
• Round-to-rectangular duct transitions
• Rectangular-to-round duct transitions
• Fan connection sections
• Cyclone connection sections
• Scrubber connection sections
• Access-door duct sections
• Inspection-opening duct sections

Industrial ducting systems may require stiffeners, supports, inspection doors and removable sections to improve durability and maintainability.

National Engineers & Steel Fabricators fabricates stiffened ducting assemblies where duct size, pressure condition, operating environment or site requirement demands additional strength.

Maintainability provisions can include:

• Access doors
• Inspection openings
• Bolted duct sections
• Flanged duct sections
• Removable spool sections
• Clean-out access
• Support brackets
• Lifting lugs
