What are the specific types of ventilation pipes?

As a very important part of air conditioning system, the material and classification of ventilation pipe are many. Each customer is in a different area and environment, and the materials of the ventilation pipes are different. So what are the types of ventilation pipes? 

1. Galvanized sheet steel composite ventilation pipe: one of the earliest composite ventilation pipes, made of galvanized sheet steel, suitable for the transportation of general gas with small moisture content, easy to rust, no heat preservation and noise reduction function, and long production and installation cycle.

2. Fiber fabric composite ventilation pipe: also known as fabric composite ventilation pipe, fabric composite ventilation pipe, fabric composite ventilation pipe, fabric air distributor. At present, it is a new type of composite ventilation pipe. It is a kind of flexible air distribution system made of special fiber (air distributors replace traditional composite ventilation pipe, air valve, diffuser, thermal insulation material, etc An air supply terminal system. The air supply terminal system that can supply air evenly mainly by the unique air supply mode of fiber penetration and orifice jet. The utility model has the advantages of face-to-face air output, large air volume, no sense of blowing, uniform distribution of overall air supply, anti condensation, easy cleaning and maintenance, healthy, environmental friendly, beautiful, high-grade, diverse colors, individualized, outstanding and light weight, negligible roof load, quiet system operation, simple installation of improving environmental quality, flexible installation of shortening work cycle, comprehensive saving of reusable system cost and high cost performance 。

3. Inorganic FRP composite ventilation pipe of Jinan ventilation pipe: a relatively new type of composite ventilation pipe, made of glass fiber reinforced inorganic materials, which is nonflammable, corrosion-resistant, heavy weight, hard but brittle, easy to deform and crack due to the influence of self weight, without heat preservation and noise reduction performance, and has a long production and installation period.

4. Composite fiberglass board composite ventilation duct: in recent years, the composite ventilation duct is made of centrifugal fiberglass board as the base material, inner fiberglass cloth, outer moisture-proof aluminum foil cloth (the imported plate is internally coated with heat sensitive black acrylic polymer, and the outer layer is thin grain cloth / aluminum foil / kraft paper). After composite drying with fire-proof adhesive, it is cut, slotted, bonded and reinforced by other processes. According to the composite ventilation duct. Appropriate reinforcement measures shall be taken for the section size and wind pressure of the air duct.
