Application of fire-retardant and high-temperature resistant air duct in fire-fighting smoke exhaust system
Fire-retardant and fire-resistant ventilation and exhaust hoses. In addition to being more convenient to use, this kind of high-temperature resistant hoses also have a relatively low transportation cost because they can be compressed and do not take up space. . It can be used for long-term high-temperature ventilation operations in a variety of high-temperature and high-pressure harsh environments, used for diesel engine test benches, automobile exhaust emissions, high-temperature boilers, used for exhaust equipment, engine structures, heating engines, solids such as dust and powder And fiber, gas environment such as steam and smoke, dust removal and extraction plant, aircraft equipment and military coordination and wind box, compressor low pressure environment. At the same time, fire-resistant, flame-retardant and high-temperature resistant ventilation hoses are widely used in fire-fighting smoke exhaust systems. The air ducts used in fire-fighting smoke exhaust systems have strict requirements on the quality of the air ducts.
As we all know, the air duct for fire fighting is fireproof. Its main function is that when a fire occurs, the fire-fighting fan is activated to remove smoke. Because in many fires, a large proportion of people are killed by smoke. Therefore, the requirements for fire-fighting smoke exhaust pipes are also extremely high. Generally speaking, the first consideration when choosing a fire-fighting smoke exhaust pipe is to have flame retardancy. We all know that fire fighting works in a high temperature or even open flame environment. Ventilation pipes must focus on fire resistance and flame retardancy.
The fire-retardant and flame-retardant duct manufacturing process used in the fire smoke exhaust system:
Material: Double-layer glass fiber cloth + 304 traveller support, any size above 100mm in diameter can be customized, temperature resistance -60℃-~+900℃ (the material can be strengthened according to customer requirements to achieve a higher temperature) Working pressure: 450mmWG/ (the material can be strengthened according to customer requirements to achieve higher working pressure) can be used to protect the screw, smooth rod, cylinder, cylinder, mandrel and other shafts. It can be used horizontally or vertically. It is recommended to use a plastic or aluminum support ring when used horizontally to maintain a certain uniform distance between the inner cavity of the shield and the screw rod to extend the service life. When the stretched length is large, a metal ring can be added to each compromise to improve the stability of the shield. Metal flanges are usually used for the connection or fixed end, and the hoop type can also be selected. It can also be used for ventilation on high-heat fans. The product has high stretch performance and can swing back and forth freely. It is made of double-layer fire-retardant glass fiber cloth stitched with good sealing performance. It can be used for high-temperature gas suction and transportation. It can also be used It has good corrosion resistance for powder transportation.
