The Industrial Challenge in Pulp & Paper Mills

Pulp and paper mills operate under intense conditions—high temperatures, corrosive pulping chemicals, scaling deposits, and erosion from abrasive fibers. These can impair heat exchangers, digesters, condensers, and vessels, leading to reduced productivity and costly maintenance. Curran International’s Pulp & Paper Mills Coating solutions mitigate these risks by extending equipment life and improving process reliability.

Curran International’s Coating Solutions for Pulp & Paper Applications

High-Performance Immersion & Corrosion-Resistant Coatings
Curran applies robust coatings like Curran 1200 and Curran 1500—100% solids epoxy systems tailored for high-temperature immersion in process streams—capable of withstanding up to 365 °F (185 °C). Chloride-heavy, fiber-laden environments benefit from these durable coatings.

Additionally, fluoropolymer coatings (e.g. PTFE, ETFE, PFA, StreaMax™) deliver strong chemical and fouling resistance—ideal for handling corrosive process fluids and abrasive fiber loads typical of pulp operations.

Structural Wear & Tubesheet Protection
Curran also offers Curran 500, a heavy-duty two-part epoxy for immersion environments, perfect for reinforcing steel surfaces against corrosion and abrasion in digesters and bleach towers.

Thermal-Spray Alloy and Surface Projects
For extreme erosion or chemical attack, Curran applies thermally sprayed alloy coatings (e.g., Alloy 825, C276) to pipes, elbows, and fabricated parts—extending the service life of critical infrastructure.

Turnkey Field and Shop Capabilities
With powerful shop facilities and a global field presence, Curran delivers coatings with reliable surface prep (NACE Level 1 dry blast), oven curing, and turnkey project execution—even during critical shutdowns.

Why Pulp & Paper Mills Coating Matters

  • Superior Corrosion & Scale Resistance
    Coatings like Curran 1200/1500 guard against chloride-induced corrosion and scaling—key in white liquor, recovery, and condensate systems.
  • Improved Heat Transfer
    Thin-film coatings and fluoropolymers maintain smooth, low-deposition surfaces, boosting thermal efficiency in heat exchangers.
  • Extended Equipment Lifespan
    The durability of Curran’s coatings and thermal alloys prolongs asset life—minimizing cost-intensive repairs or replacements.
  • Enhanced Uptime
    Curran’s in-situ services (tube lining, coating during maintenance shutdowns) support quick turnaround and improved operational reliability.

Common Applications in Pulp & Paper Mills

  • Digesters, Washers & Evaporators – High-temp immersion environments protected with Curran 1200/1500.
  • Storm/Condensate Heat Exchangers – Coated with low-energy fluoropolymers for smoother cleanup and reliability.
  • Piping, Elbows & Headers – Alloy and epoxy coatings defend against fiber-induced abrasion and corrosion.
  • Tubesheets & Water Boxes – Curran 500 protects submerged or steam-cleaned areas.
  • Shutdown-Line Maintenance – Rapid shop-based coating or thermal spray line repair during maintenance cycles.

Why Curran International Stands Out for Pulp & Paper

  • Deep Expertise in Coating Technologies
    Their suite—from hybrid epoxies to advanced fluoropolymers and alloy coatings—covers a wide array of industrial needs.
  • Global Turnkey Execution
    Curran’s major shop (Houston) plus facilities in Canada, Europe, Middle East, and Asia enable fast, high-quality deployments.
  • Proven Coating & Restoration History
    With decades in petrochemical, power, and pulp & paper sectors, Curran delivers trusted solutions to complex thermal and chemical challenges.

ROI You Can Expect

  • Reduced Maintenance & Cleaning – Coated surfaces simplify cleaning intervals and reduce downtime.
  • Improved Energy Efficiency – Maintaining clear heat-exchange surfaces supports thermal performance.
  • Lower Lifecycle Costs – Robust coatings and alloy protection slow degradation and extend service cycles.
  • Reliable Shutdowns & Restarts – Curran delivers scheduled turnaround upgrades efficiently—minimizing disruption.
