Product Description

Product Description: Mining-Grade Flexible Metal Hose

Engineered exclusively for the harsh underground mining environment, our mining-grade flexible metal hose is a rugged, safety-centric fluid transfer solution designed to meet the rigorous demands of coal mines, metal mines, and mineral processing sites. It serves as a critical component for hydraulic systems, gas extraction, slurry conveyance, and equipment connections, combining explosion-proof reliability, extreme wear resistance, and long-lasting performance.

Product Advantage

Mining-Grade Flexible Metal Hose the Following Characteristics:

Safety Compliance: Certified with Mining Product Safety Mark (MA) and flame-retardant/anti-static certifications, eliminating fire and electrostatic hazards in explosive underground zones.
Extreme Condition Adaptability: Operates reliably in temperatures ranging from -40℃ to 121℃, withstanding low-temperature brittleness and high-temperature oil degradation. Pulse life exceeds 300,000 cycles (braided type) and 1,000,000 cycles (spiral-wound type) for high-frequency vibration equipment like hydraulic supports.
Flexible & Easy Installation: Reduced bending radius (34%~47% smaller than ISO 18752 standard) enables seamless fitting in narrow tunnels, equipment joints, and complex routing. Customizable flanges or quick connectors match existing mining machinery without additional modifications.
Durability: Wear-resistant outer rubber and thickened reinforcement layer extend service life by 2~3 times compared to ordinary industrial hoses, minimizing downtime for replacements in hard-to-access underground areas.

Key Selection Tips:

Prioritize selection based on "equipment working pressure": Choose steel wire spiral type for pressure ≥31.5MPa, and braided type for pressure ≤10MPa.
For media containing solid particles (e.g., slurry), must select UHMWPE lined models to avoid rapid pipeline wear.
All underground scenarios require products with "Mining Product Safety Certification (MA Mark)"; additional flame-retardant & anti-static certification is needed for gas-related applications.
Default interfaces match mining standard flanges/quick connectors; non-standard sizes can be customized according to equipment interfaces.

FAQ

FAQ For Mining-Grade Flexible Metal Hose

Q1: What safety certifications are mandatory for mining metal hoses?
A1: All products hold the Mining Product Safety Mark (MA)1 and comply with MT/T 98. Flame-retardant & anti-static certifications are required for gas applications, meeting MSHA and GB/T 12777 standards.

Q2: Can it be customized for specific mining equipment?
A2: Yes. We offer customization for diameter (DN10~DN300), flange/quick connectors, and length. Just provide your equipment model and interface specs for seamless integration.

Q3: How long is the service life, and what's the maintenance requirement?
A: Service life is 2~3 times longer than ordinary hoses (≥3 years), and up to 5 years with customized materials. Regular visual inspections for wear or leaks are sufficient for underground use.

Q4: What is the minimum order quantity (MOQ) and lead time?
A4: MOQ is 1 unit for standard materials, and 3 units for special materials (e.g., 316L stainless steel). Lead time is 15~25 days for standard specs, 30~45 days for large-diameter or custom orders.

Q5: What warranty do you provide for mining metal hoses?
A5: We offer a 2-year warranty for all mining hoses, covering manufacturing defects. The warranty is extended to 3 years if paired with our self-developed fittings and seals.

Q6: What materials are used for the inner liner and outer cover?
A6: Inner liner options include NBR, CR, or UHMWPE (for slurry with ≤30% solid particles). The outer cover is flame-retardant, anti-static synthetic rubber, ensuring wear and moisture resistance underground.
