FAQ

Q1:What reinforcement and construction make this hose suitable for high-pressure hydraulic applications?

A1:

The hose features two high-tensile steel wire braids for reinforcement, an oil-resistant synthetic rubber inner tube, and an oil/abrasion/weather-resistant synthetic rubber cover. This double-braid design delivers exceptional strength and impulse resistance for high-pressure hydraulic oil lines, compliant with SAE 100R2A and multiple international standards (GB, DIN, RMA, AS, JIS, SABS), ensuring reliable performance in demanding mining and engineering machinery systems.

Q2:How do working and burst pressures scale with hose size for mining and engineering use?

A2:

Working pressure decreases as size increases to match flow and pressure needs:

Smaller sizes (3/16"–1/4"): 5075 PSI / 350 bar WP, 1400 bar BP (4:1 ratio)
Mid sizes (e.g., 1/2"): 3553 PSI / 245 bar WP, 980 bar BP
Larger sizes (2"): 1131 PSI / 78 bar WP, 156 bar BP Proof pressure is 2× WP across all sizes. This scaling supports high-pressure demands in multifunctional mining machinery while providing a strong safety margin against surges in petroleum or water-based hydraulic systems.

Q3:Why is the temperature range of -40°C to +121°C beneficial for this hose?

A3:

The wide operating temperature range (-40°C to +121°C) allows consistent performance in extreme conditions, from cold mining environments to hot engineering sites. The synthetic rubber materials resist thermal degradation, maintaining flexibility and sealing integrity for high-pressure hydraulic oil lines using petroleum or water-based fluids, reducing the risk of cracking or failure due to temperature fluctuations.

Q4:What customization options are available for specific mining or engineering machinery requirements?

A4:

Special specifications can be developed according to customer needs, including adjustments to sizes, lengths, reinforcement details, or other parameters while preserving SAE 100R2A compliance and compatibility with standards like GB, DIN, RMA, AS, JIS, and SABS. This enables tailored solutions for unique high-pressure hydraulic setups in mining machinery, engineering equipment, or specialized applications requiring petroleum or water-based fluid compatibility.
