China's  economy has entered a period of rapid development, people's quality of  life requirements are further improved, with the rapid development of  the construction industry is now more and more high-rise buildings, the  structure of the building is also increasingly complex, the area is also  More  and more, in this case, many buildings are using a ventilation system  for effective internal environment for the exchange of air to increase  the freshness of the protection of the workers inside the health of the  ventilation pipe on the use of more reflected in the building The building itself is more humane, but also makes the ventilation pipeline industry has been more room for development.

        Ventilation  system in the building project is actually in the actual construction,  added to the ventilation pipe some of the layout, making the building  inside the air to be effective flow, more close to the natural wind  requirements, so that the whole building has a natural ventilation and  change Gas function. But  in the ventilation system design and construction should pay attention  to is the quality of ventilation ducts will directly affect the entire  building ventilation and ventilation function, it must be on the  ventilation pipe processing technology put forward higher requirements,  so in the east Building  ventilation piping works as far as possible to choose a larger  ventilation pipe company, such a company in the production equipment  will be more advanced, so that the entire ventilation pipe construction  process can be guaranteed, because the production process is directly  related to the ventilation pipe in the Whether it can be used later
