Henderson advantage of the brand! , [] Non-combustible FRP duct, FRP duct Anshan provided by Horizon Air conditioning equipment. We are a Texas Air Conditioning Equipment Co., Ltd. Hongxin (www.hxktsb.com) located at: Shandong Dezhou specializes in: .. new air unit fresh air ventilator fan air pressure delivery outlet damper chassis outlet 1) tube and method. blue corner should transition arc, the transition radius should be 0.8 to 1.2 times the thickness in order to improve the state of the cantilever flange bearing capacity and avoid stress concentration. Requirements fiberglass mesh duct flanges should be extended to the duct body. 2) fiberglass mesh length, width, be sure to take enough ventilation methods overlap - FRP duct in order to improve the lap shear bearing capacity of inorganic glass steel duct, thereby effectively overcome the radial tensile stress, collusion bending and bending shear stress. Glass fiber cloth seams in lap length is generally 50 ~ 100mm; And each glass fiber cloth seams and joints should be a certain distance from the adjacent layers. Longitudinally between adjacent layers, the distance should be greater than the cross-lap joint 300mm, with layer lap joint distance of not less than 500mm. Dezhou, Shandong Hongxin Air Conditioning Equipment Co. fiberglass magnesium oxychloride cement composite duct (inorganic glass steel duct) has a long history of use in ventilation engineering, especially for use on the project more outstanding potential of its strong non-combustible fiberglass duct, the duct fire inspection in the basic exemption of belonging (acceptance knows the superiority of the product can ----- A grade noncombustible product) the product of the production process and the installation process and design and construction units have been approved and appreciation, it's life is not to compete with the other duct, it is indeed my company's first production installation in Changsha, Hunan region inorganic fiberglass duct systems engineering data for over 25 years now, and still In use, the degree of aging incredibly slow.
