Ventilation pipe in the life of the application is very wide, then the characteristics of the ventilation pipe we know how much?
1, ventilation pipe fire performance: the current common problem is  the finished air duct combustion performance and fire resistance without  the relevant state departments to detect, and part of the ventilation  duct material combustion performance, pipe wall thickness does not meet  the requirements.
2, low cost: ventilation pipe and the traditional brick ventilation duct, can save about 40% of the project cost;
3, light high strength: with the traditional brick ventilation duct  than the ventilation pipe light weight, high strength, can significantly  reduce the load on the building load;
4, the design flexibility: ventilation pipe can be reserved according  to the size of the hole at any time to adjust the size of the pipeline  size;
5, unique design: ventilation pipe openings installed on the flue gas  check valve and fire isolation doors, can effectively prevent the string  and string fire;
6, ventilation pipe construction is simple, an increase of indoor  space, good airtight, not back to the smoke, do not return to smelly,  can greatly improve the indoor environment.
Ventilation  ducts are dedicated to the design, manufacture and installation of  ventilation ducts, and strive to make more people enjoy the joy of  breathing, healthy work and healthy living. All walks of life are welcome to consult business negotiations.
