Characteristics of spiral duct fan in life
Spiral duct fan has been widely used in many industries around us. Purification system air duct, air conditioning air duct, industrial exhaust air duct, environmental protection system suction and exhaust pipe, mine exhaust pipe, mine rubber pipe, etc. Spiral duct is classified as duct type because it is first used for ventilation and cooling. There are many types of air ducts, so we need to learn and understand many types of air ducts.
It is named according to its purpose, but it can be used in other places, even for drainage, liquid discharge or container, so it can not be called air duct. Named according to the structure, it should be called spiral seamed thin-walled pipe. Because it is mainly made of metal, it is also called spiral seamed metal pipe. If it is classified and named according to the material, it can probably have these names: galvanized (iron) spiral pipe, stainless steel spiral pipe, aluminum spiral pipe, or in order to distinguish it from the existing stainless steel pipe, it can be called ultra-thin stainless steel pipe, because it can be rolled with 0.3mm or even thinner stainless steel strip.

Circular pipes with a diameter of 200 mm in the same installation space can replace 250 mm without increasing any pressure drop × 150mm rectangular pipe. On the premise of no additional installation space, several parallel circular pipes can replace flat rectangular pipes. Considering all factors, in most cases, the space occupied by circular pipes is less than that of rectangular pipes. For the same pressure characteristics, the installation space of several circular pipes is often the same or less than that of a rectangular pipe. Many rectangular piping systems require a 4-bolt system for installation, resulting in an increase of 40 ~ 80mm in all directions of the pipeline.
