Hose 2913003150 is a critical hydraulic fluid transmission component for Mining Hydraulic Drill Rigs. It excels in extreme mining environments—for instance, deep underground ore 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/torsion, abrasive rock dust, corrosive slurry and drastic temperature swings. These issues often cause hose burst, leakage, or premature wear, leading to hydraulic system failures and costly downtime. Yet, Hose 2913003150 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its 4-layer high-tensile steel wire reinforcement + NBR inner tube withstands 40MPa working pressure (burst pressure ≥120MPa). This eliminates burst risks caused by high hydraulic pressure spikes. Second, the synthetic rubber outer layer (Shore A 75 hardness) resists abrasion and mechanical impact. Consequently, it endures friction with rocks and equipment surfaces without damage, extending service life. Third, its excellent flexibility (minimum bending radius 150mm) adapts to tight installation spaces. Likewise, this ensures easy routing between drill rig components without kinking.
Fourth, the wide temperature adaptability (-40°C~120°C) maintains elasticity in extreme cold (high-altitude frozen mines) and heat (deep underground drilling). Above all, this prevents hose hardening or cracking in temperature extremes. Fifth, the integrated anti-corrosion treatment (inner tube oil-resistant + outer layer anti-UV) resists chemical erosion from hydraulic oil, acidic slurry and humid air. On top of that, the leak-proof crimped fittings (compatible with SAE J517 standards) ensure tight connection, avoiding oil leakage.
Unlike ordinary hydraulic hoses, this model is engineered for Mining Hydraulic Drill Rig’s high-load dynamic working conditions. To elaborate, the 4-layer steel wire structure balances pressure resistance and flexibility, while the NBR inner tube resists hydraulic oil swelling and aging. Thus, it outperforms standard hoses in service life by 130%, significantly reducing replacement-related downtime.
Our manufacturing team uses precision extrusion + high-pressure crimping technology for consistent quality. Furthermore, each unit undergoes pressure testing (40MPa for 30 minutes) and abrasion resistance verification. Additionally, the hose undergoes 100,000-cycle bending trials without performance degradation.
Notably, it adapts to extreme temperatures from -40°C to 120°C. Moreover, it passes 300-hour salt spray tests with no outer layer peeling or corrosion. In addition, it endures 2,000-hour continuous oil immersion trials without inner tube swelling.
The hose’s standard crimped fittings (customizable to BSPP/NPT threads) integrate seamlessly with mainstream Mining Hydraulic Drill Rig hydraulic systems. It requires no special tools for installation. As a result, maintenance teams can complete replacement in 15 minutes using standard wrenches.
Our quality team conducts strict ISO 9001 verification for every unit. We perform pressure resistance tests, abrasion resistance inspections, bending fatigue trials and corrosion resistance verification. Importantly, it complies with SAE J517 and ISO 1436 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 92%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 55%.
It not only ensures stable hydraulic fluid transmission but also extends drill rig hydraulic system service life by 85%. Overall, Hose 2913003150 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.
