In mountainous firefighting, if water cannot reach the fire line, it is the same as having no water. The value of forest fire hose bags can be summed up in one sentence: they allow water to cross rocks, tree roots, and steep slopes, stably delivering it to 300-500 meters away (depending on pressure and elevation difference).
Common working pressure is 1.6~4.0MPa; the higher the pressure, the longer the delivery distance. Burst pressure should reach at least 3 times the working pressure, which is a hard indicator to prevent bag bursting. During procurement, rely on data from product test reports, not just promotional pages.
Common diameters are DN40/DN50; larger diameters offer higher flow but are heavier. Lengths are configured in 20/30/50 meter sections for connection, and quick couplings determine assembly speed. It is recommended to combine "long mainline bags + short attack line bags" for configuration.
The outer layer is woven from high-strength polyester filament, resistant to friction and puncture, and can be dragged over rocks and steep slopes; the inner layer is a TPU lining, with low water resistance, cold resistance, and aging resistance. At the same specification, it is lighter than traditional rubber hose bags, allowing one person to carry multiple bags into the mountains.
Hose bags are consumable equipment; it is recommended to keep a spare ratio based on the number of teams. Longsheng'an Fire supplies forest fire hose bags and quick couplings in various specifications, and can provide configuration lists based on mission needs. Phone: 13060031111.
