Combat Abrasive
Slurry Erosion
High-strength composite repair solutions engineered for mining slurry pipelines. Restore structural integrity to erosion-damaged pipes transporting abrasive mineral slurries, tailings, and concentrate without costly shutdowns or replacements.
Critical Challenges
Slurry Pipeline Damage Mechanisms
Mining slurry transportation systems face unique degradation challenges that conventional repair methods struggle to address economically.
Erosion-Corrosion
High-velocity abrasive particles combined with corrosive process water cause accelerated wall thinning, especially at elbows, tees, and reducers.
- ▸ Wall loss rates up to 5mm/year
- ▸ Localized pitting and grooving
Pinhole Leaks
External corrosion under insulation (CUI) and internal erosion create small perforations that leak abrasive slurry, causing environmental and safety hazards.
- ▸ Difficult to weld on active systems
- ▸ Slurry solidifies around leak points
Downtime Costs
Traditional pipe replacement requires extended shutdowns, draining systems, and mobilizing welding crews--halting production and revenue.
- ▸ $50K-$200K per day in lost production
- ▸ Hot work permits in hazardous zones
Remote Locations
Mining operations are often in remote areas where mobilizing specialized welding teams, equipment, and replacement spools is logistically challenging.
- ▸ High mobilization costs and delays
- ▸ Limited access to certified welders
Slurry Settling
Shutting down slurry lines causes solids to settle and potentially plug pipes, requiring costly flushing procedures and delayed startups.
- ▸ Risk of permanent line blockage
- ▸ High water consumption for flushing
Pressure Cycling
Pump start/stop cycles and varying slurry densities create pressure fluctuations that accelerate fatigue cracking and joint failures.
- ▸ Flanged joints prone to leakage
- ▸ Weld seam stress concentration
Composite Repair Solution
Zero-Downtime Pipeline Restoration
Our engineered composite pipe repair bandage system delivers structural reinforcement to erosion-damaged slurry pipes without hot work, drainage, or extended shutdowns. The fiberglass-reinforced polyurethane wrap creates a permanent, load-bearing repair in under 60 minutes.
Rapid Emergency Response
Stop active leaks with epoxy putty, then apply bandage for structural reinforcement--system back online in 2-4 hours.
Abrasion-Resistant Barrier
Cured composite provides external protection against further erosion and impact damage at vulnerable pipe sections.
Long-Term Reinforcement
Restores hoop strength to thinned pipe walls, extending service life by 5-10 years at 10-20% of replacement cost.
Installation Protocol
Simple 5-Step Application
No specialized tools or certified welders required. Maintenance personnel can execute permanent structural repairs with minimal training.
Assess Damage
Measure wall thickness with ultrasonic gauge. Map erosion extent and leak locations.
Surface Prep
Remove scale, loose coatings, and slurry residue with wire brush. Degrease with solvent.
Seal Leaks
For active leaks: apply epoxy putty plug. Let cure 15-20 min before wrapping.
Apply Bandage
Submerge bandage in water for 5 sec. Wrap tightly with 50% overlap. Smooth air bubbles.
Cure & Test
Allow 30-60 min cure time. Verify hardness. Pressurize system and inspect for leaks.
Critical Application Note
For tailing lines and high-solids slurries, apply repair during scheduled pump maintenance windows when possible. Ensure pipe surface is clean and dry for optimal bonding. Bandage can be applied to damp surfaces but not underwater.
