Classification by Lining Material:
Lined fire hoses: These include hoses with rubber linings, polyurethane (TPU) linings, polyester resin linings, and hemp coated hoses. They are characterized by pressure resistance, wear resistance, corrosion resistance, and long service life, and are suitable for external fire scenes.
Unlined fire hoses: These include hoses made of cotton, linen, or ramie. They have lower pressure resistance and are prone to mold and corrosion, and are mostly used for fire scenes inside buildings.
Classification by Working Pressure and Inner Diameter:
Working Pressure: Common specifications include 0.8MPa, 1.0MPa, 1.3MPa, and 1.6MPa. High-pressure models can reach 2.0MPa and 2.5MPa.
Inner Diameter: Common specifications include 50mm, 65mm, 80mm, and 100mm. Other sizes include 25mm, 125mm, 150mm, and 300mm.
Classification by Function and Structure
Function: Divided into general-purpose fire hoses, wet fire hoses, anti-static fire hoses, Class A foam-specific hoses, water curtain hoses, etc.
Structure: Includes single-layer braided, double-layer braided, and internally/externally coated fire hoses.
Weaving Method: Mainly divided into plain weave fire hoses and twill weave fire hoses.
