Lining the inside of large-diameter interceptor pipelines protects against corrosive wastewater, abrasion, and microbial attack while ensuring optimal flow and structural integrity. By reducing energy losses, maintenance needs, and environmental risks, these coatings deliver clear operational and financial advantages.

 

​

1. Corrosion Protection

• Forms a chemical barrier against hydrogen sulfide, organic acids, and chlorides that eat away at steel and concrete.

• Prevents pitting, thinning, and premature pipeline failure.

 

2. Abrasion and Erosion Resistance

• Shields against sand, grit, and other solids carried in the flow that scour the pipe wall.

• Maintains wall thickness and avoids costly erosion-induced repairs.

 

3. Hydraulic Efficiency and Flow Optimization

• Creates a smooth internal surface that minimizes friction and head loss.

• Improves flow capacity and reduces pumping energy consumption.

 

4. Microbial-Induced Corrosion (MIC) Prevention

• Inhibits biofilm development and sulfide-oxidizing bacteria that accelerate localized corrosion.

• Mitigates underfilm attack and maintains coating adhesion over time.

 

5. Structural Integrity and Leak Prevention

• Seals microcracks, weld seams, and surface defects to preserve pipeline continuity.

• Reduces infiltration/inflow risks and protects surrounding soils and groundwater.

 

6. Maintenance and Inspection Simplification

• Smooth, nonporous coatings ease robotic inspection, inline cleaning, and condition assessment.

• Cuts down on unplanned shutdowns and labor-intensive cleaning cycles.

 

7. Extended Service Life and Lifecycle Cost Savings

• Delays the need for rehabilitation or replacement by decades.

• Enables predictable maintenance schedules and lowers total cost of ownership.

 

8. Environmental Compliance and Safety

• Contains leaks and spills, safeguarding communities and ecosystems.

• Helps meet regulatory standards for wastewater conveyance and workplace safety.
