Lined fire hoses are primarily hose↕ s used to transport flame retardant liquids such☆♣α as high pressure water or foam. The traditionalβ♠ fire hose is lined with rub ®≥♥ber and the outer surface is covered↓‍ with linen weave. Advanced fire hoses a♣‌βre made of polymeric materi≥≈÷δals such as polyurethane. The fire hos→φ≤e has metal fittings at both ends. Itα↔<& can be connected to ♠©another hose to extend t $≠he distance or connect the nozzle to increasγ♦Ω♦e the liquid injection pressuααre. The performance of the linin​ ↓g fire hose is also ver‍&₩y high. For example, the fabric layer of the♥​ water belt should be evenly woven and tα¥he surface should be clean; no double ≈$warp, double warp, jump a☆εφ→nd scratch. Secondly, the thickness of the water ​≥♦lining (or covering layer) should be uniform, an₹π"d the surface should be smoo∞  ★th and flat without wrinkles or other de✔÷$fects.
