The application range of the spiral air pipe machine is very wide. Purifying system return air pipe, central air conditioning ventilation pipe, industrial air supply and exhaust ventilation pipe, environmental protection system suction and exhaust air pipe, mine gas drainage pipe, mine rubberized fabric air cylinder, etc. Spiral duct is classified as air duct because it was first used for ventilation and cooling.

Spiral Corrugated Culvert Pipe Machine
The name given according to its purpose, but it can also be used in other places, even for draining water, discharging liquid or as a container, which cannot be called an air duct. Named after its structure, it should be called spiral slit thin-walled tube, because it is mainly made of metal and is also called spiral slit metal tube. If named according to material classification, there are probably several names: galvanized (iron) spiral pipe, stainless steel spiral pipe, aluminum spiral pipe, or in order to distinguish 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.
Spiral Corrugated Posttension Pipe Machine BPT-135/150
Without increasing any pressure drop, a circular pipe with a diameter of 200mm in the same installation space can replace a rectangular pipe with a diameter of 250× 150 mm. On the premise of not increasing additional installation space, several parallel circular pipes can replace flat rectangular pipes. Considering all the factors, in most cases, circular pipes take up less space than rectangular pipes. For the same pressure characteristics, the installation space of several circular pipes is often the same as or less than that of one rectangular pipe. Many rectangular pipe systems require a 4-bolt system for installation, thus adding 40-80 mm in all directions of the pipe.
