Great properties of flexible PU hose
A fire fighting hose is a layflat tube designed to transport high-pressure water or fire-retardant liquids like foam. Traditional hoses use rubber linings with polyester reinforcement, while advanced models employ polymers like PU for durability. Metal connectors at both ends allow attaching extensions or nozzles to increase spray pressure.
Key Maintenance Methods
1. Dedicated Management
Assign a Custodian: Designate a staff member to oversee hose inventory and condition.
Categorize and Register: Classify hoses by quality, assign unique IDs, and maintain a detailed log. Track usage, inspections, and repairs.
Training: Regularly educate teams on proper handling and maintenance protocols to ensure compliance.
2. Optimal Storage
Dedicated Storage Area: Use a ventilated room or designated space with controlled temperature (avoid extreme heat/cold).
Layflat Hose Storage: Roll hoses in single layers on racks. For long-term storage:
Turn hoses over twice annually to prevent flattening.
Swap ends or refold hoses to equalize wear.
Vehicle Hose Care: On fire trucks, prevent hoses from rubbing against each other. Adjust their position periodically to avoid abrasion.
3. Proper Usage Guidelines
Avoid Sudden Movements: When deploying hoses, prevent sharp bends or twisting, which can damage internal layers.
Protect During Use:
Never drag water-filled hoses across rough surfaces—lift or use rollers instead.
Keep hoses away from corrosive substances (oil, acids, alkalis) and direct flames.
In high-heat environments (e.g., near flames), use cotton/linen hoses for better heat resistance.
