When it comes to the ventilation pipe, everyone will think that it is usually installed in the living room to install the air circulation. In fact, there is nothing wrong with it. The installation of the main ventilation pipe usually has professional technology, which is not clear to us, but there is also a friend who is interested in the size and installation specifications of the ventilation pipe, so today's editor will give you the size and installation specifications of the ventilation pipe.
1. At present, the planning of oil smoke ventilation pipes and specifications must conform to national standards, and must have product qualification certificate, quality and inspection certificate. If the ventilation pipes do not conform to the plan specified by national standards, they can attack safety accidents and form unnecessary injuries in the process of use. Therefore, in selecting the size and specifications of the ventilation pipes, it is also required to have certain basic knowledge of the ventilation pipes Knowledge. The size of ventilation pipe is about 2000 * 450, which is a large ventilation pipe.
2. In general, when purchasing the ventilation pipe, there are dimensions, requirements and other information in the specification. In addition, if you don't believe it, you can calculate the wind speed by multiplying the cross-sectional area of the wind pipe by 3600. For those calculating the size of the ventilation pipe, the second best is no more than 15m, and the second best is 8-12m. When installing the ventilation pipe, both ends of the ventilation pipe shall roll flexibly without obvious scratches.
3. In fact, there are many kinds of ventilation pipes, including fiberglass ventilation pipes, steel plate ventilation pipes, combined data ventilation pipes, stainless steel ventilation pipes, plastic ventilation pipes, single-sided color steel ventilation pipes, etc. According to its use to distinguish, there are industrial exhaust air duct, air conditioning ventilation air duct, gas ventilation air duct, purification system ventilation air duct, etc., which can be used in different places; if according to the shape of the ventilation pipe, it will be spiral, circular, rectangular, etc., and the size of each section of ventilation pipe will be different.
4. In the front, we have a general understanding of the size, classification and shape of ventilation pipes. Secondly, there is another classification, which is the most important. During installation, the distance between hanger opening and ventilation pipe intubation opening shall not be less than 20cm. The bolt spacing of flange pipe shall be between 100 mm and 150 mm, the flange pipe shall be isolated independently, and the material shall be the same as the installation material of ventilation pipe.
5. If you want to install the ventilation pipe of the bath dam, its standard size needs 300 * 300 mm, or 300 * 600, and its diameter is about 100-150. The size of the ventilation pipe should be selected according to the area of the home. According to the national code, the specification of the ventilation pipe is below 40cm, and the distance of the ceiling shall not be greater than 4m. If the ventilation pipe is above 40cm, the distance of the ceiling shall not be greater than 3m. According to the different installation methods of ventilation pipes, the installation specifications are also different, which can be straight-line installation or parallel installation.
Conclusion: To sum up, the size and installation specifications of ventilation pipe mainly have the above five points. The installation of ventilation pipe can make the air flow smoothly, so more attention should be paid to the installation, otherwise it will not have any effect!
