Hose 29130031581 is an elite-class ultra-high-pressure hydraulic transmission component exclusively engineered for Mining Hydraulic Drill Rigs. It excels in the most extreme mining scenarios—for instance, ultra-deep underground hard rock mines (≥2500m depth), high-altitude quarries (≥4500m), large-scale tunnel boring projects, and high-intensity continuous drilling sites with frequent extreme pressure spikes.
These ultra-harsh environments pose unparalleled challenges for hydraulic hoses: ultra-high system pressure (up to 70MPa), violent continuous vibration (55G), heavy rock fall impact, highly corrosive acidic/alkaline slurry, and extreme temperature swings (-70°C~180°C). These issues often lead to hose impact damage, bursting, crushing, rapid aging, or leakage, causing catastrophic hydraulic system failures and prolonged downtime. Yet, Hose 29130031581 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points of extreme mining operations.
First, its NBR/PTFE elite composite inner tube + 9-layer high-density stainless steel braid reinforcement withstands 70MPa working pressure and 280MPa burst pressure. This eliminates leakage or bursting caused by sudden extreme pressure surges during heavy-load drilling. Second, the anti-impact six-layer outer cover (Shore A 98 hardness) resists heavy rock impact (≤500N) and severe dust abrasion. Consequently, it extends service life by 200% compared to standard hydraulic hoses. Third, the PTFE-enhanced inner tube ensures zero swelling and excellent compatibility with all hydraulic oils (ISO VG 32/46/68/100/150/220/320/460/680). Likewise, this maintains stable flow rate and pressure transmission for long-term continuous operation.
Fourth, the advanced anti-aging, anti-UV, and anti-corrosion formula in the outer cover resists chemical erosion from mining slurry and ultraviolet radiation. Above all, this prevents brittle cracking and extends service life in humid, highly corrosive underground environments. Fifth, the ultra-wide temperature adaptability (-70°C~180°C) ensures reliable operation in ultra-freezing high-altitude mines (-70°C) and ultra-high-heat deep mining (180°C). On top of that, the 9-layer braid design enhances structural stability, avoiding kinking, deformation, and crushing during complex drill rig movements and heavy load compression.
Unlike ordinary hydraulic hoses, this model is tailored for the ultra-high-pressure, ultra-intensity working conditions of modern Mining Hydraulic Drill Rigs. To elaborate, the NBR/PTFE elite composite inner tube combines superior oil resistance (NBR) and extreme high-temperature stability (PTFE), while the 9-layer braid provides exceptional pressure resistance and anti-impact performance without sacrificing flexibility. Thus, it outperforms generic hoses in service life by 190%, significantly reducing replacement-related downtime.
Our manufacturing team uses precision co-extrusion + high-speed braiding (2000rpm) technology for uniform tube thickness and braid density. Furthermore, each unit undergoes 70MPa pressure testing (180 minutes) and 100% leak verification. Additionally, the hose undergoes 250,000-cycle bending trials and 180,000-cycle vibration trials to ensure no fatigue damage.
Notably, it adapts to extreme temperatures from -70°C (polar or high-altitude frozen mines) to 180°C (high-load hydraulic systems). Moreover, it passes 600-hour salt spray tests with no braid rust or outer layer peeling. In addition, it endures 18,000-hour oil immersion trials without performance degradation.
The hose’s standard hydraulic fittings (BSPP/SAE/JIC/Metric) integrate seamlessly with mainstream Mining Hydraulic Drill Rig hydraulic systems. It requires no special adapters for installation. As a result, maintenance teams can complete replacement in 10 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform pressure resistance tests, impact/crush/abrasion resistance inspections, bending/vibration fatigue trials and corrosion resistance verification. Importantly, it complies with ISO 1436-1 and SAE 100R21 international ultra-high-pressure hydraulic hose standards.
Compatible with top Mining Hydraulic Drill Rig brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces hose-related failure rates by 99%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 72%.
It not only ensures stable ultra-high-pressure hydraulic oil transmission but also extends the service life of drill rig hydraulic systems by 115%. Overall, Hose 29130031581 delivers industry-leading performance for long-term ultra-high-intensity mining operations. Beyond that, it minimizes downtime caused by hose failures, maximizing operational efficiency and project profitability.
