Smoke exhaust pipe is widely used in hotels and factories. The smoke exhaust system is a system that discharges smoke outside the building through mechanical smoke exhaust or natural ventilation. The mechanical smoke control system is composed of air supply and exhaust ducts, tube wells, fire dampers, door switchgear, air supply and exhaust fans and other equipment.

In real life and work, we often see a collapsible and foldable pipe, which has strong heat exhaust, wind protection and ventilation functions. This is because in practical application, the smoke exhaust pipe is generally installed in various vents, which is a fire safety pipe. The first pipe of the smoke exhaust pipe extends outward to play the role of smoke exhaust and ventilation, and the second pipe delivers a large amount of air and oxygen to the room. By squeezing the air in a specific environment, It can transport indoor smoke and harmful gases. During use, the high-quality smoke exhaust pipe can withstand a fire for nearly 200 minutes, effectively ensuring the safety of indoor and outdoor personnel and property. The powerful function of smoke control pipe mainly depends on the production of its high-quality raw materials. The smoke control pipe adopts high resistance materials such as thermal insulation color steel and double-sided embossed color steel, which is an essential product in modern entertainment production and living places. If it is necessary to install smoke control pipe, cooperate with regular enterprises, and let professional technicians operate it to ensure the later use effect.
