Assembled fire-resistant and thermal insulation integrated ventilation duct: the metal layer, thermal insulation layer, fire-resistant layer, etc. are integrated into a whole through their own processes. The size of the formed plates, special-shaped pieces, etc. are manufactured by factory according to the drawings. After being transported to the site, they can be directly assembled and formed, and then hoisted. The products can fully meet the pressure resistance, fire resistance and thermal insulation limit requirements specified in the use occasions and industry specifications.
The product has high strength, and can meet the requirements of smoke control and exhaust air duct of more than or equal to 3000 Pa, and the use standard for high-pressure occasions (subject to the report)
The panel fire protection A1 level report, pressure resistance report, green certification, fire resistance and heat insulation report are complete, which can meet the re inspection requirements!
The fire resistance and heat insulation are required to be 30 minutes, 60 minutes, 90 minutes, 120 minutes, 180 minutes, depending on the requirements!
Scope of use: schools, hospitals, chemical plants, high-speed railways, subways, airports, exhibition halls, etc
In addition, the application of ventilation ducts is particularly extensive, especially in outdoor applications.
Therefore, some ventilation pipes used outdoors must have good corrosion resistance. At the same time, most of the ventilation pipes and equipment on the market are made of metal materials. Therefore, these metal equipment also need to have good oxidation resistance. If some metal equipment is very easy to be oxidized, the pipeline damage will be accelerated with the increasingly serious oxidation.
