Fire Hose Fittings can be classified into various models and specifications according to different types of interfaces, sizes, and connection methods. The common classifications are as follows:
Classified by Interface Type:
Internal Lug Interface: Connected through internal threads or clamping structure, which is secure and suitable for high-pressure environments.
External Lug Interface: Connected through external threads or clamping structure, which is convenient to install and suitable for scenarios requiring quick disassembly.
Quick Coupler Interface: Using a specially designed quick-connect mechanism, such as pin-type, knob-type, etc., it can achieve a connection and disconnection within seconds, greatly improving the efficiency of fire-fighting operations.
Classified by Size Specifications:
Common Sizes: 1 inch, 1.5 inches, 2 inches, 2.5 inches, 3 inches, etc., corresponding to the diameter of the water hose.
Nominal diameter: DN50, DN65, DN80, DN100, DN50, etc., need to match the interface of equipment such as fire hoses, hydrants, and fire engines.
Classification by connection method:
Internal fixed interface: installed at the outlet of hydrants, fire pumps, etc.
Pipe thread interface: installed at the water gun inlet end. Reducer interface used for the connection between different caliber fire fighting equipment, such as KJ50-65, 65-80, etc.
Specific models and uses
KD65 internal thread type live interface:
Model: KD65.
Specifications: 2.5 inches, nominal diameter DN65.
Use used for the connection between fire hoses and fire engines, hydrants, water guns, to transport pressurized water or mixed fire extinguishing agent for fire fighting.
Pipe thread interface:
Specifications: installed at the water gun inlet end.
Use: connect the water gun with the fire hose to ensure smooth water flow.
Reder interface:
Specifications: such as KJ50-65, 65-80, etc.
Use: used for the connection between different caliber fighting equipment to solve the problem of interface mismatch.
Material and performance Material:
Aluminum alloy: lightweight and high strength, good corrosion resistance, suitable for fire fighting scenarios.
Performance:
Pressure resistance: usually has pressure ratings of 1.0MPa, 1.6MPa, 2.5Pa, etc., and needs to be selected according to the actual working pressure of the fire system. Sealing performance: using rubber, silicone and other elastic materials as seals to ensure the sealing at the interface.
