　　通風管道主要作用是用于輸送和分布風量（空氣） 。通風管按外形分為圓形和矩形。通風管除直管外， 還有彎頭、天圓地方、變徑彎， 三通、四通等管件組成。通風管道按材質分為普通薄鋼板，鍍鋅薄鋼板、不銹鋼板、鋁板等金屬風管、硬聚氯乙烯塑料板、塑料復合鋼板和玻璃鋼風管等。風管保溫有橡塑保溫和玻璃棉保溫，一般選用橡塑保溫。

　　The main function of ventilation ducts is to transport and distribute air volume (air). Ventilation ducts are divided into circular and rectangular shapes according to their appearance. In addition to straight pipes, ventilation ducts also consist of fittings such as elbows, roundabouts, variable diameter bends, tees, and crosses. Ventilation ducts are divided into ordinary thin steel plates, galvanized thin steel plates, stainless steel plates, aluminum plates and other metal ducts, rigid polyvinyl chloride plastic plates, plastic composite steel plates, and fiberglass ducts according to their materials. There are rubber insulation and glass wool insulation for air ducts, and rubber insulation is generally used.

　　通風管道工程概述通風管道是為了使空氣流通，降低有害氣體濃度的一種市政基礎設施。通風管的制作與安裝所用板材、型材以及其他主要成品材料，應符合設計及相關產品現(xiàn)行標準的規(guī)定，并應用出廠檢驗合格證明。

　　Overview of Ventilation Duct Engineering Ventilation ducts are a type of municipal infrastructure designed to facilitate air circulation and reduce the concentration of harmful gases. The plates, profiles, and other main finished materials used in the production and installation of ventilation ducts shall comply with the current national standards for design and related products, and shall be accompanied by factory inspection certificates.
