Flame retardant hoses are mainly used for hydraulic transmission, power transmission, or conveyors in flammable, high-pressure, and high-temperature environments. Widely used in industries such as chemical, marine, petroleum, and metallurgy. Classification of fire hoses: chloroprene fire resistant rubber hoses, armored fire resistant hoses, fire resistant oil well control hoses, etc.
Fire resistance of the hose: it can provide a working pressure of 15 minutes at 750 ° C.

Oil resistance: Immersed in hydraulic oil at 40 ° C to 100 ° C, without damage for 24 hours.

Flame retardant hose acid resistance: Immerse in 4% NaOH solution and 4% HCL solution within 24 hours without significant changes.

4. Pressure resistance: Under a pressure of 52.5MPa, there is no leakage after being stable for 5 minutes, the failure pressure is greater than 105MPa, and there is no deformation on the surface of the pipeline.

5. Refractory hose insulation: Place the tube shell in an environment between 300 ° C and 50 ° C, inject clean water within 20 minutes, and the temperature ratio inside and outside the tube is 1:40.
