Advantages and disadvantages Advantage Brief composite duct of: thermal insulation effect, and can save insulation material that can be done at one time the connection flange on the duct when making long life, acid, corrosion can save a brush installation The paint process. Manufacturing and installation costs are relatively lower than galvanized steel duct. Disadvantages: live production processing difficulties flange plate duct must be produced at the factory molds, large transportation costs. The cross-sectional area of ??the composite material with air duct pipe insulation in the case do not take up much space, big drag. Quality identification: 1. Look material density, density material to manufacturers to provide tables. 2. Look surface finish. 3. knocking, knocking it sounds pleasant than efficiency, as selected tile a reason.
