High temperature resistant air  duct, resistance to high temperature expansion pipe outer have strong steel ring protection, can on the ground optionally drag and won't wear duct. Also can bear the weight of the object. Fire. Waterproof. Acid and alkali resistant, High performance; 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, high temperature resistant duct, resistance to high temperature expansion pipe has good high temperature resistance, resistant to bad environment and aging performance.

High temperature resistant air duct, resistance to high temperature expansion pipe as exhaust gas tube, resistance to vibration, exterior wear-resisting protection, strong toughness, (exhaust gas temperature to + 200 ℃) is suitable for 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, wind power equipment, fire smoke and other heavy work environment of air supply and exhaust, set in addition to the use of smoke and dust
