air duct Application: the engine exhaust gas extraction; Wear force strong solid, such as dust and fiber, Active strong medium, such as steam and smoke, industrial dust removal and suction, chemical industry, Used for welding waste flue gas extraction, air conditioning and ventilation equipment; Room, basement, tunnels, municipal pipeline engineering, mechanical shipbuilding engineering, mining ventilation equipment, fire smoke and other heavy work environment of air supply and exhaust, set in addition to the use of smoke and dust.

  air  duct  Characteristic: high performance-to-price ratio; Vibration resistance; External through the spiral wire have wear protective effect, good alkali metal acidproof performance, flame retardancy, Toughness is strong; The bending radius and diameter about the same. Has not air leakage, wear resistance, corrosion resistance, antistatic, wind resistance is small, compressive strength is strong wait for an advantage
