Upgrading Bag Filter Housings in Steel Manufacturing

Background: Airborne particulate removal is critical in steel manufacturing, especially from furnace exhaust systems. Traditionally, stainless steel (SS) housings were used; however, recurring issues such as leaks, corrosion, and inconsistent quality resulted in higher costs and frequent downtime for a leading steel producer.

The Challenge:

The operation team faced multiple challenges with the SS housings:

  • Frequent leakages requiring intervention
  • Corrosion damage leading to premature replacement
  • Unplanned downtime affecting production continuity
  • Rising costs from spares and maintenance
