What are the specifications and sizes of fire-resistant silicone fiberglass braided hoses!

The fire hoses used are dn25, dn32, dn40, dn50, dn70, dn80, dn10, dn15, dn20.

The size of fire hydrant pipe, sprinkler pipe and galvanized manifold shall be determined according to the design flow. There are provisions in the Building Rules and the High Rules. The standpipe diameter is above DN100, the water spray pipe is above DN25, the nozzle is DN25, the second nozzle is DN32, and the 3-4 nozzle is DN40.

1. Protect the environment and protect the health of workers
Silicone Glass Fiber Tube itself has special tensile strength, no wrinkle or break, sulfur-resistant, halogen-free, pure oxygen is non-flammable, excellent insulation performance, cured silicone, safe and environmentally friendly, and effectively improves performance. Protect the health of workers and reduce the occurrence of occupational diseases. Unlike asbestos products, it is harmful to people and the environment.
2. Excellent heat resistance
The silicone structure on the surface of the refractory shell has "organic groups" and "inorganic structures", which combine the properties of organic substances with the functions of inorganic substances. Compared with other polymer materials, its most notable feature is high temperature resistance. When the silicon-oxygen molecular chain is used as the main chain structure, the CC bond becomes 82.6kcal/mol, while in silicone, the silicon-O bond becomes 121Kcg, so the thermal stability is high and the chemical bond is broken. I can't do it. Decomposes at high temperatures. Silicone is not only resistant to high temperature, but also resistant to low temperature, so it can be used in various temperatures. Chemical and physical mechanical properties do not change much with temperature.
3. Anti-splash and multiple protection
In the smelting industry, the medium temperature of the electric furnace is extremely high. Even in the welding industry, it is easy to produce high-temperature molten droplets. After forming slag in pipes and steel cables, it cools, solidifies and hardens. The rubber outer layer of the pipe eventually becomes brittle and breaks. The multi-layer silicon-coated fireproof shell provides multiple safety protections at temperatures up to 1300°C, preventing damage to unprotected equipment and cables, and preventing hot melts such as molten iron, copper, and aluminum from flying, and effectively preventing them. Peripheral cables and equipment.
