high temperature resistance and ventilation tube, crankcase ventilation hose has stable chemical properties, does not constitute any pollution to the environment, internal adopts special glass fiber cladding, thermal isolation fiber, coating glue; External coating special glass fiber, spiraling clamp type structure, stainless steel ( VA) ; Acid and alkali resistance, chemical waste, flame retardant, wear-resistant, resistant to pull and any expansion of universal shift, and other functions; This series of ventilation pipe used in high temperature hot gas boiler smoke, car exhaust emissions, solder cigarette factory, blast heater eduction and welding gas discharge, used for exhaust equipment, engine structure, heat engines, such as dust, solid powder and fiber, such as steam and smoke gas environment, dust removal and extraction plant, heaters, aircraft equipment and military harmonic bellows and compressor, low pressure environment.

high temperature resistance and ventilation tube, crankcase ventilation tube on each attribute index introduced:

1. Strength: the mechanical structure is stable, compressive resistance to deformation.

2。 Small coefficient of thermal conductivity: the architectural institute of 0. 024w( M。 K) , better than other commonly used thermal insulation material.

3。 Fire prevention performance is good: more than the national standard GB8624 - 97 pipe heat insulation foam plastics combustion performance grading method in the BI level requirement. In the polyurethane industry reached leading level at home and abroad.

4。 No pollution: ventilation tube inside and outside for the aluminum foil, the surface of AL2O3 has stable chemical properties, does not constitute any pollution to the environment.

5。 Long service life: ventilation tube inside and outside for aluminum plate, the surface has the stable AL2O3, middle insulation layer is a polymer material, the service life of the four to six times that of the traditional ventilation tube.

6。 Light: the weight of 2. 0, is 1/5 ~ 1/6 of the traditional ventilation pipe.

7。 Airtight performance: no leakage. Ventilation pipe is widely used in high pressure air supply system.
