The difference between PVC fire hose and polyurethane fire hose

The difference between PVC fire hose and polyurethane fire hose

Rubber lined fire hose: It is made of high-strength synthetic fiber woven into a tubular jacket, and then lined with rubber, which is pressure-resistant, wear-resistant, corrosion-resistant, impermeable, low water flow resistance, fast water flow, light and soft, and long service life It can be matched with fire hydrants and fire pumps (vehicles) to transport water or other fire extinguishing agents. It can also be widely used in industrial and mining, shipping, petrochemical, agricultural and other fields. technical parameter.
Glue-lined belt: Using high-strength synthetic fiber (high-quality polyester filament, polyester staple fiber) as raw materials, weaving into a tubular jacket, and then lined with rubber, it has pressure resistance, wear resistance, corrosion resistance, impermeability, water flow It has the characteristics of low resistance, fast water flow, light weight and softness, and long service life. It can be matched with fire hydrants, fire pumps (vehicles), transport water or other fire extinguishing agents, and can also be widely used in industrial and mining, shipping, petrochemical, agricultural and other fields.
PVC hose structure: The outer layer of the hose is woven from polyester yarn, polyester yarn, and polypropylene yarn, and the lining is pvc.
Product features: resistant to high pressure, resistant to use, and non-leakage.
Product use: Widely used in fire fighting, water supply or transportation of other liquids. It is a supporting product for fire hydrants, fire trucks, and fire pumps; it is a necessary fire fighting equipment for hotels, office buildings, airports, stations, warehouses and other places.
Polyurethane fire hose:
The product has excellent comprehensive performance and has many valuable characteristics from rubber to plastic. First, it has high strength, and its tear strength is about 3 times that of natural rubber; second, it has good abrasion resistance, about 3-5 times that of natural rubber; third, it has good oil resistance and low affinity with non-mineral oils. It is hardly corroded in fuel oil. Fourth, it has good weather resistance. It can be continuously used in a high temperature environment of 80°C to 90°C and will not be embrittled at a low temperature of -50°C to -70°C. The polyurethane-lined fire hose produced with imported equipment and imported raw materials, in addition to all the advantages of rubber hose, also has excellent high pressure resistance, oil resistance, weather resistance, corrosion resistance, bending resistance, etc., and it is light in weight and soft in use. Convenient, the weight per unit length is more than 40% lighter than the rubber-lined hose. It is a new-generation product that reduces the fighting strength of the firefighting force and improves the fire-fighting performance. It is favored by the majority of users. This product has long become a mainstream fire hose in developed countries such as Japan, Europe and the United States, and is even used by the public as an ordinary water pipe for washing flowers and plants. In our country, because of the high cost of raw materials, the more expensive prices, and most of the equipment imported, it was not promoted until the late 1990s. At present, most firefighting forces have begun to equip polyurethane fire hoses, and many industrial and mining enterprises, petrochemical oil depots, ship terminals, and high-end buildings have begun to use them in large quantities.
The fire hose is made of high-strength synthetic chemical fiber as the woven rubber as the lining, and the two are tightly combined under the action of high pressure. It is an ideal supporting product for fire-fighting equipment. It can also be widely used in shipping, petrochemical, water conservancy, greening and other fields.
