As a kind of common ventilation duct, high temperature resistant air duct, what should be noticed when using air duct
When using high temperature air ducts, we must first clarify the temperature endurance limit of the product. If the temperature exceeds the product limit temperature, the air duct will not be durable. For example, air duct ventilation with a high temperature resistance of 400 degrees means that the instantaneous temperature reaches 450 degrees, and the temperature is around 400 degrees for a long time, so the temperature cannot exceed 450 degrees for a long time. If the air duct exceeds the limit temperature of the product during use, the duct will not be durable due to the use of it beyond the temperature range for a long time. Therefore, when using high-temperature air ducts or other industrial hoses, they must be kept at the standard temperature. The highest temperature can be reached in an instant, but the standard temperature cannot be exceeded for a long time to avoid rupture of the air duct.
High temperature resistant telescopic air duct should also pay attention to its pressure resistance range. There are two types of positive pressure and negative pressure. The positive pressure duct is used for exhausting or ventilating; the negative pressure duct is used for exhaust and negative pressure. The air duct can be used for ventilation and exhaust air, while the positive pressure air duct is used for exhausting air. If the pressure is too high, the air duct will be flattened or broken. Therefore, it is necessary to distinguish whether it is exhausted or exhausted when using it.
