The metal hose of the fire sprinkler pipe is an important component of the fire protection system, and its parameters are crucial for ensuring the normal operation of the system. The following are some common parameters of metal hoses for fire sprinkler pipes:
1、Basic Materials and Construction
Pipe material: Usually made of 304 or 316 stainless steel, these two materials have strong corrosion resistance and are suitable for various harsh environments.
Construction: The hose body is a thin-walled stainless steel tube formed by hydraulic pressure, which has strong flexibility, stretchability, bending and anti vibration capabilities. The strengthened protection of the woven mesh sleeve gives it higher pressure bearing capacity.
2、Connection and size
Connection methods: various connection methods such as flanges, threaded connections, quick couplings, etc., to meet different installation requirements.
Diameter range: DN8-DN1200mm, covering various specifications from small to large diameters.
3、Pressure and temperature
Work pressure: PN0.6-6.4MPa, the specific pressure level needs to be selected according to the actual application scenario.
Temperature range: -196 ℃~420 ℃ (or -20 ℃~+180 ℃, depending on usage conditions and hose type), ensuring that the hose can work normally in a temperature environment.
4、Other parameters
Hose length: can be customized according to user needs to accommodate different installation spaces and pipeline layouts.
Special functions: such as sealing performance, vibration reduction, noise reduction, etc., which help improve the overall performance of the fire protection system.
