In process ventilation systems, an unsuitable material or wall thickness can increase maintenance requirements, reduce system reliability, and lead to unexpected replacement costs. To achieve long-term performance, ducting should be selected according to the demands of the process, the conveyed material, and the operating environment. For applications in demanding industries, Nordfab offers a range of solutions, including mild steel ducting.

Mild Steel Ducting is designed for industrial ventilation, vacuum systems, and pneumatic conveying applications handling abrasive materials. Manufactured in heavier-gauge steel than standard ventilation ducting, it provides a robust solution for industrial processes where durability is a key requirement.

Examples of applications where mild steel ducting is advised include:

• Industrial manufacturing facilities using central extraction systems for process ventilation or material transport.
• Vacuum conveying installations, where materials are transported through closed pipe systems using negative pressure.
• Pneumatic conveying systems used to move bulk materials, dust, or production waste between processing stages. 

As different materials require different transport velocities to remain suspended in the airflow, proper sizing helps maintain the required airflow throughout the system and supports efficient material transport. For example, wood chips and sawdust typically convey effectively at air velocities between 18 and 22 m/s.

Nordfab's Mild Steel Ducting is available in a range of diameters and can be supplied with either flanged, straight or clipped-edge connections to suit different installation requirements. Standard systems are finished with a protective RAL 7032 coating, while alternative materials and thicknesses can be supplied when needed making the system adaptable to a wide range of industrial requirements.
