What is the standard for fire hose design?

Fire hose standards usually include the following accpects：

1.Material standards：The outer layer of fire hose is usually made of synthetic rubber or polymer materials，and the inner layer is made of synthetic fiber materials to ensure wear resistance and high pressure resistance.

2.Size standard: The length of fire hose is usually 15 meters,20 meters,3o meters,the diameter is usually 1 inch, 1.5inches or 2.5inches, These dimensions can be adjusted according to actual needs.

3.Working pressure standard:The working pressure of fire hose is usually 0.8MPa, and the maximun working pressure can reach 1.2MPa

4.Temperature resistance standards:Fire hoses are usually able to withsatnd high temperatures and are generally required to withstand temperature rangjing from -20~60 ℃

5. Corrosion resistance standards: Fire hoses are usually required to have certain corrosion resistance and be able to resist erosion by chemicals such as acids and alkalis.
