Hose 2913003151 is a critical hydraulic fluid transmission component for Mining Hydraulic Drill Rigs. It excels in extreme mining environments—for instance, underground metal mines, high-altitude hard rock quarries, large-scale tunnel boring projects and dusty construction sites.
These settings pose unique challenges for hydraulic hoses: high system pressure, frequent bending/vibration (up to 35G), abrasive rock dust, corrosive slurry and drastic temperature swings. These issues often cause hose leakage, bursting, or premature wear, leading to hydraulic system failures and costly downtime. Yet, Hose 2913003151 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its NBR synthetic rubber inner tube + 4-layer stainless steel braid reinforcement withstands 40MPa working pressure and 160MPa burst pressure. This eliminates leakage or bursting caused by high hydraulic pressure spikes. Second, the anti-abrasion outer layer (Shore A 75 hardness) resists scraping from rock edges and dust. Consequently, it extends service life by 130% compared to standard hydraulic hoses. Third, its flexible structure (minimum bending radius ≥150mm) adapts to tight installation spaces. Likewise, this avoids kinking during drill rig movement, ensuring unobstructed oil flow.
Fourth, the NBR inner tube is oil-resistant and compatible with all common hydraulic oils (ISO VG 32/46/68). Above all, this prevents tube swelling or degradation, maintaining flow rate stability for long-term use. Fifth, the wide temperature adaptability (-40°C~120°C) ensures reliable operation in freezing high-altitude mines and high-heat underground drilling environments. On top of that, the stainless steel braid resists rust and corrosion from acidic slurry, further enhancing durability.
Unlike ordinary hydraulic hoses, this model is engineered for Mining Hydraulic Drill Rig’s dynamic working conditions. To elaborate, the multi-layer reinforcement balances pressure resistance and flexibility, while the anti-kink design avoids flow restriction during drill movement. Thus, it outperforms generic hoses in service life by 140%, significantly reducing replacement-related downtime.
Our manufacturing team uses precision extrusion + braiding technology for uniform tube thickness. Furthermore, each unit undergoes pressure testing (40MPa for 30 minutes) and leak verification. Additionally, the hose undergoes 100,000-cycle bending trials to ensure no fatigue damage.
Notably, it adapts to extreme temperatures from -40°C (polar or high-altitude mines) to 120°C (high-load hydraulic systems). Moreover, it passes 300-hour salt spray tests with no braid rust or outer layer peeling. In addition, it endures 5,000-hour oil immersion trials without performance degradation.
The hose’s standard hydraulic fittings (BSPP/SAE) 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 15 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform pressure resistance tests, wear resistance inspections, bending fatigue trials and corrosion resistance verification. Importantly, it complies with ISO 1436-1 international hydraulic hose standards.
Compatible with top Mining Hydraulic Drill Rig brands, it serves as a direct OEM replacement. Thanks to its durability, it reduces hose-related failure rates by 93%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 58%.
It not only ensures stable hydraulic oil transmission but also extends the service life of drill rig hydraulic systems by 85%. Overall, Hose 2913003151 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it minimizes downtime caused by hose failures, maximizing operational efficiency and project profitability.
