1. It is necessary to clarify the temperature resistance limit of the product. The use of the product beyond the limit temperature will cause the air duct to not be durable. For example, 400-degree high temperature duct ventilation refers to use at room temperature of 400 degrees, and the instantaneous temperature reaches 450 degrees (only for short-term use). If it is used for a long time at a temperature beyond the limit range that the air duct can bear, it will cause the air duct to be ineffective. Therefore, when using high-temperature air ducts or other industrial hoses, it must be kept at the standard temperature. It is okay to reach the highest temperature in an instant, but it cannot exceed the standard temperature for a long time to avoid rupture of the air duct.
2. There are retractable and non-retractable air ducts for high temperature resistance. When using, it should be noted that non-retractable air ducts cannot be compressed together, and should not exceed their minimum bending radius when bending; Do not overstretch, and do not stretch too hard beyond its standard length.
3. Pay attention to the pressure range when using high-temperature air ducts. There are two types of positive pressure and negative pressure. The positive pressure air duct is used for exhaust or ventilation; Exhaust and positive pressure air ducts are used for air extraction, if the pressure is too high, the air duct will be flattened or broken, so when using it, it is necessary to distinguish whether it is exhausted or exhausted.
4. the size of the air duct, the high temperature resistant telescopic air duct is generally used for industrial ventilation and exhaust air, and is usually used by installing the high temperature resistant air duct on the production equipment. Therefore, the diameter of the high temperature resistant air duct must be the same as the connecting equipment. If the diameter of the air duct is too large, it may cause air leakage at the interface after connecting the equipment, and normal exhaust air cannot be completed. Certain restrictions directly affect the normal operation of our industrial equipment.
5. The circulating medium in the air duct, the circulating medium in the pipe is different, and the hoses used are also different. Some circulating mediums are chemical products. At this time, the high temperature resistant air duct we use must be able to prevent the corrosion of chemical products, and The high temperature resistant air duct we choose should be able to meet the requirements of the concentration and temperature of the circulating medium. We use high temperature resistant air ducts of different materials for the medium of different compositions.
