Large-caliber high-temperature resistant air duct, high-temperature resistant air duct is made of high-quality glass fiber coated cloth, covered with a layer of copper-plated steel wire as the support of the overall structure, high-temperature air duct has good flexibility, wear resistance Negative pressure, glass fiber is a material with strong fire-retardant insulation. Because of the built-in steel wire as a support, it can be dragged on the ground at will without being damaged.
  High temperature resistant air ducts are widely used in various special machinery, high temperature boilers, high temperature induced draft fans, hot gas discharge, etc. The high temperature resistant air duct is made of (multi-layer) special glass fiber, heat insulation fiber plus high temperature coating, and high-strength fiber line. The upper and lower ends of the material are clamped by metal clamps. The appearance is more beautiful, and the surface metal ring can withstand any Drag without affecting the tube wall. The weight is ultra-light, suitable for use in various places such as ventilation and exhaust, very strong and tough, the bending radius is approximately equal to the outer diameter; the compression ratio is 1:5.
   high temperature resistant air ducts are dedicated to various special machinery, high temperature boilers, hot gas discharge, etc. The highest temperature resistance is 1100 degrees, and it is used in the occasions where flame-retardant hoses are required; used in solids such as dust, powder and fiber; used in gaseous media such as steam and smoke, used in industrial dust removal and exhaust stations, flue gas emissions, blast furnaces Exhaust gas emissions and welding gas emissions. Its good heat resistance is formed by the external clip type to form abrasion protection; high toughness and high flame retardancy are selected by all walks of life.

  So how to distinguish high-quality and inferior high-temperature air ducts?
   First of all, look at the surface of the high temperature resistant air duct. The surface is clean, free of thorns, and the workmanship is not rough and free of dirt. Generally speaking, this is not the point. It is mainly to distinguish its performance. High-quality high temperature resistant air ducts have excellent performance. High temperature resistance, acid and alkali resistance, flame retardant, abrasion resistance, free drag on the ground will not cause wear, stretch resistance and other high-quality properties, generally observe these properties first to distinguish.
   Next, during the trial period, check whether there are small holes or worn areas and the density of the tube body during ventilation, so that you can roughly estimate the life of the high-temperature air duct. The high-quality high-temperature air duct does not burn , No shrinkage, no deformation, no pungent or toxic gas, no dense smoke, and low product density.
   Finally, the quality of high temperature resistant air ducts is ultra-light. Generally, the bulky air ducts are either because of the large number of specifications, otherwise the steel wire used in the inner covering is inferior. High-quality high temperature resistant air ducts are light in weight. Because it can reduce the load-bearing capacity of the mechanical structure in terms of construction, it is non-toxic and tasteless. It is a new type of environmentally friendly air duct with strong elasticity and flexibility, anti-ultraviolet, strong corrosion resistance, and durability.
