Hose 2913003153 is a high-performance hydraulic transmission component exclusively designed for Mining Hydraulic Drill Rigs. It excels in extreme mining scenarios—for instance, deep underground coal mines, high-altitude hard rock quarries, large-scale tunnel boring projects and muddy construction sites.
These environments pose severe challenges for hydraulic hoses: frequent pressure spikes (up to 45MPa), continuous vibration (38G), abrasive rock dust, corrosive acidic slurry and drastic temperature swings. These issues often lead to hose leakage, bursting, torsion damage or premature wear, causing costly hydraulic system downtime. Yet, Hose 2913003153 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points of mining operations.
First, its NBR synthetic rubber inner tube + 5-layer stainless steel braid reinforcement withstands 45MPa working pressure and 180MPa burst pressure. This eliminates leakage or bursting caused by sudden pressure surges in hydraulic systems. Second, the ultra-wear outer layer (Shore A 80 hardness) resists scraping from rock edges and dust abrasion. Consequently, it extends service life by 150% compared to standard hydraulic hoses. Third, the anti-torsion structural design prevents twisting during drill rig movement. Likewise, this maintains unobstructed oil flow and avoids internal fiber damage.
Fourth, the NBR inner tube is fully compatible with hydraulic oils (ISO VG 32/46/68/100) and resistant to swelling. Above all, this ensures stable flow rate and pressure transmission for long-term use. Fifth, the wide temperature adaptability (-45°C~130°C) ensures reliable operation in freezing high-altitude mines (-45°C) and high-heat underground drilling (130°C). On top of that, the stainless steel braid + anti-corrosion coating resists rust and chemical erosion from acidic slurry, enhancing durability in humid mining environments.
Unlike ordinary hydraulic hoses, this model is engineered for the dynamic working conditions of Mining Hydraulic Drill Rigs. To elaborate, the 5-layer braid balances pressure resistance and flexibility, while the anti-torsion design adapts to frequent drill movement. Thus, it outperforms generic hoses in service life by 145%, significantly reducing replacement-related downtime.
Our manufacturing team uses precision extrusion + high-speed braiding technology for uniform tube thickness and braid density. Furthermore, each unit undergoes 45MPa pressure testing (30 minutes) and leak verification. Additionally, the hose undergoes 120,000-cycle bending trials and 50,000-cycle torsion trials to ensure no fatigue damage.
Notably, it adapts to extreme temperatures from -45°C (polar or high-altitude mines) to 130°C (high-load hydraulic systems). Moreover, it passes 350-hour salt spray tests with no braid rust or outer layer peeling. In addition, it endures 6,000-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 12 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform pressure resistance tests, wear resistance inspections, bending/torsion 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 reliability, it reduces hose-related failure rates by 94%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 60%.
It not only ensures stable hydraulic oil transmission but also extends the service life of drill rig hydraulic systems by 90%. Overall, Hose 2913003153 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.
