The 8 inch fire hose is more and more used in sewage treatment. The length of the 8 inch fire hose is usually determined according to our application environment. How long should the 8 inch fire hose be under normal conditions? Usually in order to be able to produce conveniently, fire hose manufactures will choose direct production of 20 meters 1 fire hose if the user does not have a standard case, because such length of fire hose is not only conducive to production, but also the application of more common length. But not all the length of the fire hose is the same, if we have other standards for the length of the application of the fire hose, we can completely negotiate with the manufacturer. After all, the manufacturer is not a dealer, this is the reason why more and more users choose direct cooperation with the fire hose manufacturers. So, in order to let more people understand the agricultural fire hose industry, let’s take a look at the characteristics of PU lined fire hose, why so many people like to use PU lined fire hose:
1. PU (Polyurethane) is characterized by good resistance to high pressure and low temperature. It can not only adapt to high temperature of more than 100 degrees, but also maintain softness in low temperature of minus 60 degrees;
2. The aging resistance of polyurethane is relatively good, which can moderately increase the service life of the fire hose and reduce the replacement frequency of the fire hose;
3. The leather of PU hose for modern agricultural facilities is made of high-strength polyester filament which is finely woven by circular looms. Such materials can achieve the pressure-resistant performance of fire hose to ensure the fire hose
Above is about the reason that most people like to choose polyurethane lining fire hose, hope to be helpful to you.
