Slurry discharge hose
Nitrile-lined rubber slurry hose engineered for high-pressure tailings transfer with extreme abrasion resistance. Handles sharp ore particles at high velocity without premature wear.
Best for: tailings transfer, mill discharge, cyclone feed, mine dewatering discharge
Heavy duty rubber slurry hose
Our heavy-duty rubber slurry hose is purpose-built for the most demanding tailings transfer applications. The nitrile rubber tube provides exceptional resistance to the cutting and gouging action of sharp ore particles, while the helix wire reinforcement maintains full bore under vacuum conditions and prevents kinking during handling.
The abrasion-resistant cover withstands dragging over rough terrain and exposure to harsh mine-site conditions. Each hose is manufactured to tight dimensional tolerances for reliable coupling fit and consistent flow performance.
Challenges solved by correct slurry hose selection
Tailings hose wear-through in 3 months
Standard rubber hoses handling coarse tailings often wear through in under a season, causing unplanned downtime and environmental spill risk. Our nitrile-lined slurry hose delivers up to 5x longer service life in high-velocity abrasive applications, with a replaceable wear tube option for the most extreme conditions.
Coupling blow-offs at high pressure
Inadequate coupling retention on slurry lines operating above 200 PSI creates a serious safety hazard. Our hoses feature factory-crimped flanged or victaulic couplings with 100% pressure testing, eliminating blow-off risks. The helix wire reinforcement also prevents coupling pull-out by maintaining hose dimensional stability under pressure.
Slurry settling inside hose during shutdown
When slurry pumps stop, heavy solids settle inside the hose, creating blockages that require disassembly and manual cleaning to restart. Our hose's smooth inner bore reduces settling points, and we recommend self-draining hose routing configurations that minimize solids accumulation during planned shutdowns.
Case study: Copper mine tailings transfer, Peru
How switching to nitrile-lined slurry hose extended service life from 3 months to 14 months.
Situation: A large copper mine in the Peruvian Andes was experiencing slurry hose wear-through every 3–4 months on their tailings transfer lines. The coarse, angular ore particles were cutting through standard SBR rubber tubes, causing frequent line changes and spill cleanup.
Solution: Switched to our nitrile-lined heavy duty rubber slurry hose with increased wall thickness and helix wire reinforcement. Flanged couplings were crimped and pressure-tested to 450 PSI before installation.
Outcome: Hose service life extended to 14 months — a 4.7x improvement. Unplanned downtime for hose replacement dropped from 4 times per year to less than once per year. Annual hose replacement costs reduced by over 60%.
Slurry discharge hose FAQ
Abrasion resistance in slurry hose comes from the tube compound. Our nitrile-lined slurry hose uses a high-acrylonitrile rubber formulation that withstands the cutting action of sharp ore particles. The helix wire reinforcement prevents collapse under vacuum while maintaining flexibility, and the thick cover layer adds further protection against external wear from dragging on rough surfaces.
Our heavy-duty rubber slurry hose is rated up to 300 PSI working pressure, with a 4:1 safety factor. The actual pressure rating depends on hose diameter — smaller diameters (2-4 inch) handle higher pressures, while larger diameters (8-12 inch) are typically used for gravity or low-pressure discharge. We recommend selecting a hose rated at least 25% above your maximum operating pressure for continuous tailings transfer.
Slurry discharge hoses can be fitted with flanged couplings (ANSI 150# or PN10/16), heavy-duty camlock fittings, or victaulic/grooved couplings for quick connection. For high-pressure applications over 150 PSI, we recommend flanged or victaulic connections with gaskets to prevent blow-offs. All couplings are crimped with our hydraulic crimping machine and impulse-tested before shipment.
