Ventilation ducts are generally divided into three types of materials: white iron (galvanized) ventilation ducts, fiberglass ventilation ducts, and composite material ventilation ducts;

1、凈化空調系統用通風管道 【鍍鋅版、不銹鋼】

1. Ventilation ducts for purification air conditioning systems [galvanized version, stainless steel]

2、系統用通風管道【鍍鋅板、彩鋼保溫板】

2. Ventilation ducts for central systems [galvanized sheet, color steel insulation board]

3、環境控制系統用風管【鍍鋅板、不銹鋼】

3. Air ducts for environmental control systems [galvanized sheet, stainless steel]

4、工業通風系統用風管【鋼板、鍍鋅板】

4. Air ducts for industrial ventilation systems [steel plates, galvanized sheets]

無機玻璃鋼通風管道

Inorganic fiberglass ventilation ducts

無機玻璃鋼通風管道又稱為玻鎂風管，是以改性菱鎂水泥為膠結料，摻入有機或無機填充料，并用中堿玻璃纖維布進行增強而制成的一種管材。具有不燃燒、耐腐蝕、強度高和重量輕等特點，被廣泛應用于賓館、飯店、大型商場、寫字樓的空調工程以及礦井通風、工廠排煙、除塵等工程。在建筑工程、地下工程及工業廠房的通風中，它已經完全取代了不耐燃的有機玻璃鋼通風管，并在逐步取代防腐性能差的鍍鋅鐵皮通風管。尤其是在濕度大的地下工程和長江以南地區，它的優越性更為顯著。

Inorganic fiberglass ventilation ducts, also known as glass magnesium ducts, are a type of pipe material made from modified magnesite cement as a binder, mixed with organic or inorganic fillers, and reinforced with medium alkali glass fiber cloth. It has the characteristics of non combustion, corrosion resistance, high strength, and light weight, and is widely used in the air conditioning engineering of hotels, restaurants, large shopping malls, office buildings, as well as mine ventilation, factory smoke exhaust, dust removal and other engineering. In the ventilation of building engineering, underground engineering, and industrial factories, it has completely replaced the non combustible organic glass reinforced plastic ventilation pipes, and is gradually replacing the galvanized iron sheet ventilation pipes with poor anti-corrosion performance. Especially in underground projects with high humidity and areas south of the Yangtze River, its advantages are even more significant.

分類

classification

根據國家建筑材料行業標準JC646-1996標準的規定，無機玻璃鋼通風管道按用途分為P類管和D類管兩種。P類管主要用于公共建筑、人防工程及一般需要安裝通風及空調設施的工業廠房和礦井等，作通風管、排煙管和排塵管；D類管則主要用作住宅建筑的通風管、排油煙管。

According to the national building materials industry standard JC646-1996, inorganic fiberglass ventilation pipes are divided into two types according to their purpose: P-type pipes and D-type pipes. P-type pipes are mainly used in public buildings, civil air defense projects, and industrial factories and mines that generally require the installation of ventilation and air conditioning facilities, as ventilation pipes, smoke exhaust pipes, and dust exhaust pipes; Class D pipes are mainly used as ventilation pipes and oil fume exhaust pipes in residential buildings.

產品質量等級

Product quality level

根據無機玻璃鋼通風管道的物理力學性能和外觀質量，無機玻璃鋼通風管道分為一級品和合格品兩個等級。

According to the physical and mechanical properties and appearance quality of inorganic fiberglass ventilation pipes, they are divided into two levels: first level products and qualified products.

產品規格

Product specifications

無機玻璃鋼通風管道的尺寸主要由設計單位根據工程需要的通風量進行設計，也可根據客戶的具體要求設計。

The size of inorganic fiberglass ventilation ducts is mainly designed by the design unit based on the ventilation volume required by the project, and can also be designed according to the specific requirements of the customer.

無機玻璃鋼通風管道的外形分圓形和矩形兩種截面。管道的長一般為2～3m，如果圓形管直徑和矩形管的邊長大于1.5m時，管段長度可適當縮短。管段之間的連接方式有兩種：一是法蘭連接，一是承插式連接

The appearance of inorganic fiberglass ventilation ducts can be divided into two sections: circular and rectangular. The length of a pipeline is generally 2-3m. If the diameter of a circular pipe and the side length of a rectangular pipe are greater than 1.5m, the length of the pipe section can be appropriately shortened. There are two connection methods between pipe sections: flange connection and socket connection
