8'' Ore Transfer Hose Multi Layer Rubber Structure Enhanced Impact Vibration Absorption
Introduction
The Flame-Resistant Mining Hose is built for underground mining operations where fire safety is critical. Made from flame-retardant rubber compounds and featuring anti-static properties, it helps reduce fire hazards and electrostatic discharge. Its structure is engineered to carry water, foam, and other fire suppression agents with reliability and safety. The rugged outer jacket withstands abrasion and impact, making it ideal for confined and hazardous environments.

Features
Lightweight Options for Portable Use
Lightweight PVC or composite hoses are ideal for applications requiring frequent movement or temporary installations.
End Connection Versatility
Compatible with flanges, camlocks, couplings, or quick-connect fittings, ensuring easy integration into existing systems.
External Wear Protection Options
Hoses can be supplied with an extra outer cover or protective rings to resist external wear, dragging, or contact with sharp objects.
Low Permeability to Fluids and Gases
Especially in composite hoses, multiple barrier layers ensure minimal leakage of chemicals, water, or gases during transport.
Application
► Underground Coal Mines
► Tunneling Operations
► Fire Suppression Systems
► Emergency Water Supply
Advantages
UV and Weather Resistance
Outer covers are UV-stabilized and weatherproof, enabling long-term outdoor use without degradation from sunlight or rain.
Flame Retardant Options Available
Flame-resistant hoses are manufactured with MSHA-approved materials for enhanced safety in underground coal mines and explosive zones.
Anti Static Properties
Built-in anti-static layers prevent the buildup and discharge of static electricity, reducing the risk of ignition in flammable environments.
Reinforced for High Durability
Multiple reinforcement layers (synthetic cord, steel wire, or fabric) offer excellent strength and burst protection, especially under high loads.
