Hose 29130031541 is a premium ultra-high-pressure hydraulic transmission component tailored for Mining Hydraulic Drill Rigs. It excels in extreme mining scenarios—for instance, deep underground metal mines, high-altitude hard rock quarries, large-scale tunnel boring projects and high-intensity drilling sites with frequent pressure fluctuations.
These environments pose severe challenges for hydraulic hoses: ultra-high system pressure (up to 50MPa), intense continuous vibration (42G), sharp rock abrasion, corrosive acidic slurry and drastic temperature swings (-50°C~140°C). These issues often lead to hose cracking, bursting, rapid wear or leakage, causing costly hydraulic system downtime and safety risks. Yet, Hose 29130031541 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points of mining operations.
First, its NBR/PVC composite inner tube + 6-layer stainless steel braid reinforcement withstands 50MPa working pressure and 200MPa burst pressure. This eliminates leakage or bursting caused by sudden pressure surges in high-intensity drilling. Second, the anti-crack double-layer outer cover (Shore A 85 hardness) resists sharp rock scraping and dust abrasion. Consequently, it extends service life by 160% compared to standard hydraulic hoses. Third, the flexible structure (minimum bending radius ≥120mm) adapts to complex drill rig movements. Likewise, this avoids kinking and cracking during frequent bending, ensuring unobstructed oil flow.
Fourth, the NBR/PVC composite inner tube is fully compatible with all hydraulic oils (ISO VG 32/46/68/100/150) and resists swelling, aging and chemical erosion. Above all, this ensures stable flow rate and pressure transmission for long-term continuous operation. Fifth, the wide temperature adaptability (-50°C~140°C) ensures reliable operation in freezing high-altitude mines (-50°C) and ultra-high-heat underground drilling (140°C). On top of that, the 6-layer stainless steel braid + anti-corrosion coating resists rust and acidic slurry erosion, enhancing durability in humid mining environments.
Unlike ordinary hydraulic hoses, this model is engineered for the ultra-high-pressure dynamic working conditions of Mining Hydraulic Drill Rigs. To elaborate, the 6-layer braid balances extreme pressure resistance and flexibility, while the double-layer outer cover prevents cracking from mechanical impact. Thus, it outperforms generic hoses in service life by 150%, significantly reducing replacement-related downtime.
Our manufacturing team uses precision co-extrusion + high-speed braiding technology for uniform tube thickness and braid density. Furthermore, each unit undergoes 50MPa pressure testing (60 minutes) and leak verification. Additionally, the hose undergoes 150,000-cycle bending trials and 80,000-cycle vibration trials to ensure no fatigue damage.
Notably, it adapts to extreme temperatures from -50°C (polar or high-altitude mines) to 140°C (high-load hydraulic systems). Moreover, it passes 400-hour salt spray tests with no braid rust or outer layer peeling. In addition, it endures 8,000-hour oil immersion trials without performance degradation.
The hose’s standard hydraulic fittings (BSPP/SAE/JIC) 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, wear resistance inspections, bending/vibration fatigue trials and corrosion resistance verification. Importantly, it complies with ISO 1436-1 and SAE 100R13 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 95%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 62%.
It not only ensures stable ultra-high-pressure hydraulic oil transmission but also extends the service life of drill rig hydraulic systems by 95%. Overall, Hose 29130031541 delivers cost-effective, high-performance results for long-term mining operations. Beyond that, it minimizes downtime caused by hose failures, maximizing operational efficiency and project profitability.
