Requirements for material selection of ventilation and smoke exhaust pipes

There are many ventilation and smoke exhaust pipes in life, so what are the requirements for material selection of ventilation and smoke exhaust pipes? Let's take a look at it

When the surface layer of the air duct is made of aluminum foil, in order to ensure that the surface layer is not easy to be damaged, the material and thickness of the aluminum foil are specified, and the thickness of the aluminum foil and reinforced material of the air duct surface layer is specified.

Secondly, the thin steel plate flange is firmly bonded in the ventilation smoke exhaust pipe, the outer surface and the internal insulation material, which is one of the basic conditions to ensure the composite material. Plate defects that exceed a certain area not only affect the service life of the air duct, but also sometimes reduce its insulation effect. Therefore, the defect shall not be greater than 6‰ to achieve the normal use of the material in the system.

At present, non-metallic air duct materials develop rapidly, there are many varieties, and their characteristics and advantages are more and more widely used. In order to ensure the safety in use, it is proposed that the air pipes made of these materials should have non-combustible or non-combustible B1 level combustion performance requirements according to the needs of the project, and the surface layer needs to be non-combustible materials.

Only in the processing of the air duct with quality assurance, the ventilation and smoke exhaust pipe can play its role, so that customers can achieve the desired effect when using, and truly satisfied with the service of the ventilation and smoke exhaust pipe.
