At present, there are many kinds of ventilation pipes. As a new type of FRP pipe, inorganic FRP pipe has many advantages and wide application. It is a kind of air pipe used in fire control and smoke exhaust engineering. The combustion performance of this product meets the requirements of class A1, and it has good fire prevention performance, high strength, moisture-proof and water-proof.

　　一般用于大型餐廳廚房、大型工廠車間、大型娛樂場所、等領域無機玻璃鋼風管無機玻璃鋼風管壁厚大于鐵皮風管，具有良好的隔音性能。兩端采用法蘭和螺釘連接，同類產品的減振降噪效果較為理想無機玻璃鋼風管選用耐腐蝕、抗彎、抗凍、防潮等材料，生產中采用整體成型結構。

　　It is generally used in large restaurants, kitchens, large factories, large entertainment places, shopping malls and other fields. The wall thickness of the inorganic glass fiber reinforced plastic air duct is larger than that of the iron sheet air duct. It has good sound insulation performance. The two ends are connected by flange and screw. The vibration reduction and noise reduction effect of similar products is ideal. The inorganic FRP air duct is made of corrosion-resistant, bending resistant, frost resistant, moisture-proof and other excellent materials, and the overall forming structure is used in the production.

　　兩端選用橡膠墊和無機材料，采用法蘭連接，提高整體結構質量和密封性，提高無機玻璃鋼風管的使用壽命。玻璃鋼是一種新型復合材料，發展快、應用廣、工藝檔次高，具有強大的生命力。有機玻璃鋼風管管壁結構合理，能充分發揮材料的作用，在滿足使用強度的前提下，提高了鋼度，保證了產品的穩定性和可靠性。

　　Rubber pad and inorganic material are selected at both ends, and flange connection is adopted to improve the overall structural quality and sealing performance, and improve the service life of inorganic FRP air duct. FRP is a new type of composite material, which has rapid development, wide application, high technology level and strong vitality. The structure of PMMA air duct wall is reasonable and advanced, which can give full play to the role of materials. On the premise of meeting the use strength, it improves the steel degree and ensures the stability and reliability of the product.
