Hose 29130031571 is a top-tier ultra-high-pressure hydraulic transmission component exclusively engineered for Mining Hydraulic Drill Rigs. It excels in the most demanding mining scenarios—for instance, deep underground hard rock mines (≥2000m depth), high-altitude quarries (≥4000m), large-scale tunnel boring projects, and high-intensity continuous drilling sites with frequent pressure spikes.
These extreme environments pose unprecedented challenges for hydraulic hoses: ultra-high system pressure (up to 65MPa), violent continuous vibration (50G), heavy rock fall impact, corrosive acidic/alkaline slurry, and extreme temperature swings (-65°C~170°C). These issues often lead to hose crushing, bursting, rapid aging, or leakage, causing catastrophic hydraulic system failures and prolonged downtime. Yet, Hose 29130031571 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points of mining operations.
First, its NBR/PTFE premium composite inner tube + 8-layer high-strength stainless steel braid reinforcement withstands 65MPa working pressure and 260MPa burst pressure. This eliminates leakage or bursting caused by sudden pressure surges during heavy-load drilling. Second, the anti-crush five-layer outer cover (Shore A 95 hardness) resists heavy rock impact and severe dust abrasion. Consequently, it extends service life by 190% compared to standard hydraulic hoses. Third, the PTFE-enhanced inner tube ensures zero swelling and excellent oil compatibility (ISO VG 32/46/68/100/150/220/320/460). likewise, this maintains stable flow rate and pressure transmission for long-term continuous operation.
Fourth, the anti-aging and anti-UV 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, corrosive underground environments. Fifth, the wide temperature adaptability (-65°C~170°C) ensures reliable operation in freezing high-altitude mines (-65°C) and ultra-high-heat deep mining (170°C). On top of that, the 8-layer braid design enhances structural stability, avoiding kinking and deformation during complex drill rig movements and heavy load compression.
Unlike ordinary hydraulic hoses, this model is tailored for the ultra-high-pressure, high-intensity working conditions of modern Mining Hydraulic Drill Rigs. To elaborate, the NBR/PTFE premium composite inner tube combines oil resistance (NBR) and high-temperature stability (PTFE), while the 8-layer braid provides extreme pressure resistance and anti-crush performance without sacrificing flexibility. Thus, it outperforms generic hoses in service life by 180%, significantly reducing replacement-related downtime.
Our manufacturing team uses precision co-extrusion + high-speed braiding (1800rpm) technology for uniform tube thickness and braid density. Furthermore, each unit undergoes 65MPa pressure testing (150 minutes) and 100% leak verification. Additionally, the hose undergoes 220,000-cycle bending trials and 150,000-cycle vibration trials to ensure no fatigue damage.
Notably, it adapts to extreme temperatures from -65°C (polar or high-altitude frozen mines) to 170°C (high-load hydraulic systems). Moreover, it passes 550-hour salt spray tests with no braid rust or outer layer peeling. In addition, it endures 15,000-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, crush/abrasion/tear resistance inspections, bending/vibration fatigue trials and corrosion resistance verification. Importantly, it complies with ISO 1436-1 and SAE 100R19 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 98%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 70%.
It not only ensures stable ultra-high-pressure hydraulic oil transmission but also extends the service life of drill rig hydraulic systems by 110%. Overall, Hose 29130031571 delivers industry-leading performance for long-term high-intensity mining operations. Beyond that, it minimizes downtime caused by hose failures, maximizing operational efficiency and project profitability.
