Composite Rehabilitation for Air Handling & Emission Control Systems

Air handling and emission control equipment operate in harsh industrial environments where corrosion, abrasion, vibration, and thermal cycling are common. Over time, these conditions can lead to wall loss, structural weakening, leaks, and reduced system efficiency.

RAK Industrial Services provides composite-based rehabilitation solutions for baghouses, chimneys, stacks, exhaust systems, and related air handling configurations. Our repair systems restore structural integrity and improve reliability and are often able to be completed without shutdown.

Protecting Air Handling Systems Without Major Downtime

Maintaining dust collection and exhaust systems is critical for plant safety, operational efficiency, and environmental compliance. Deterioration in air handling structures can lead to uncontrolled dust release, reduced airflow performance, and non-compliance with emissions requirements.

RAK evaluates structural condition, corrosion severity, operating temperatures, and airflow demands to design composite repair systems that stabilize weakened areas, restore long-term performance, and are designed for the customer’s specific environmental exposure.

Composite Rehabilitation Provides
  • Structural reinforcement of corroded or thin-wall conditions
  • Abrasion and corrosion resistant protection
  • Repairs completed without hot work in sensitive environments
  • Installation while systems remain in service, when conditions allow
  • Extended service life of existing infrastructure
  • Restoration of airflow integrity and system performance
  • Targeted reinforcement at high-wear zones, seams, and connection points
  • Repairs that conform to complex geometries and support structures
  • Reduced risk of dust release and containment breaches
  • Cost-effective alternative to replacement or large-scale outages

Chimney & Stack Reinforcement

Stacks and chimneys experience corrosion, thermal cycling, vibration, and environmental exposure that can weaken structural integrity over time. RAK’s systems are well-suited for facilities implementing emissions upgrades, duct modifications, or ongoing corrosion mitigation programs.

Composite chimney and stack reinforcement provides:

  • Structural strengthening without significant added weight
  • Corrosion and abrasive resistant protective barriers
  • Reinforcement of cracked or weakened sections of infrastructure
  • Minimal to no disruption to plant operations

In-Service Repair
Composite systems allow structural reinforcement of stacks and chimneys without requiring shutdown in many operating conditions.

Baghouse Rehabilitation

Baghouses are continually exposed to particulate abrasion, moisture, and corrosive process conditions. All repairs are designed to support continued operation and assist facilities in maintaining compliance with EPA air quality requirements.

RAK provides composite-based baghouse rehabilitation systems that:

  • Reinforce deteriorated baghouse walls, ducting, and structural panels
  • Seal air leakage pathways
  • Protect against continued corrosion and abrasion
  • Restore airflow integrity and collection efficiency
