Universal high-temperature air duct, resistance to high temperature expansion pipe CP structure, wall material: special high temperature fiber coating; Spiral wire, stainless steel (VA); 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.

    Universal high-temperature  air duct , resistance to high temperature expansion pipe used in 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.
