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.
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.
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.
