PP Pipe Diameter for Air Ducts:

φ125 to φ1500mm (diameter and thickness appropriately matched), stepless selection.

PP Duct Product Features: Compared to the traditional hand-forged galvanized iron pipes, mechanically produced spiral ducts offer the following advantages:

(1) Good sealing properties.

(2) Good strength and rigidity.

(3) Low ventilation resistance and noise, round pipes outperform square pipes.

(4) Easy installation, with fewer connection points.

(5) High quality, aesthetically pleasing.

Composite ductwork is made from a combination of various inorganic materials, categorized into different types based on their composition, but most are lightweight, porous, and have high thermal resistance.
