Water hose classification
Classification Basis
Type
Technical Characteristics
By Material
Rubber-lined Fire Hose
Natural/synthetic rubber lining, wear-resistant and pressure-resistant (working pressure ≥1.0MPa)
PVC-lined Fire Hose
Polyvinyl chloride lining, lightweight (30% lighter than rubber), excellent corrosion resistance
Polyurethane-lined Fire Hose
High elasticity, low flow resistance, suitable for high-pressure scenarios (burst pressure ≥3.0MPa)
By Working Pressure
Low-pressure Hose (0.8~1.3MPa)
Civil building general fire, mainly 65mm in diameter
Medium-pressure Hose (1.3~2.5MPa)
Industrial fire, with Kevlar reinforcement layer, diameter 50~80mm
High-pressure Hose (≥2.5MPa)
Petrochemical/special rescue, metal wire braided reinforcement, burst pressure ≥4.8MPa
By Structure
Single-layer Braided Hose
Basic type, suitable for indoor fire hydrants
Double-layer Braided Hose
Outer layer aramid + inner layer polyester, abrasion resistance increased by 40%
Coated Hose
Externally coated with polyurethane water layer, mold-proof and UV-resistant (outdoor service life ≥5 years)
