At present, many stainless steel flue processing requires the use of industrial air ducts, that is, pipelines. The operation process of pipelines is convenient and fast for everyone's production, processing and work, but special regulations are also used when using, otherwise there will be no In order to ensure the required expected goals, the following is a brief introduction to the special regulations for the construction of pipeline construction projects.
1. For complex commercial buildings, pay attention to the scheme design. Various anti-corrosion and thermal insulation engineering projects, ground engineering projects, LED energy-saving lamps of power supply companies and construction engineering professionals must first negotiate and negotiate the scope of separation, and establish each project. The absolute elevation range of a pipeline. In most cases, it is forbidden to oversize the pipeline boundary of its own relevant laws and regulations. If some pipelines need to be bypassed, other engineering projects need to be negotiated and carried out.
2. The standard for dealing with the collision and harmony of various common-plate flange ventilation pipes is: "small pipes let thick pipes, and pressure let no pressure". For example, if the water pipe collides with the pipeline, it should be the turn of the water pipe. If the cooling and heating pipes collide with the sewage pipes, the cooling and heating pipes should be changed.
3. The product engineer who is in charge of the design plan before the construction of the common plate flange ventilation duct construction project shall draw the pipelines and single lines of the workers in each post on a plan design. Use a colored pencil for each line. Comprehensive absolute elevations at each junction point to see if there are any differences, to properly handle problems, and to solve problems before using them. The overall classification of common plate flange ventilation ducts can be divided into two categories: natural ventilation and indoor ventilation of mechanical equipment. The two classifications are different, and the basic elements of indoor ventilation are also different. At present, everyone can master the basic elements of indoor ventilation of these two fully welded air ducts.
natural ventilation:
The work rate of this type of common plate flange ventilation duct is the "press fit" caused by the outdoor gas temperature difference in the house and the "tire pressure standard" caused by outdoor gas damage. The basic elements of indoor ventilation are basically the temperature difference. When the indoor air quality quality temperature is higher than the outdoor air temperature, the air in the room will increase due to its low relative density and will be discharged from the home page. The lower temperature and denser outdoor gas is introduced into the room according to the lower door leaf. The larger the outdoor air temperature difference in the room, the larger the difference in aspect ratio between the left and right window holes, the larger the area of the window holes, and the greater the gas flow.
Mechanical equipment indoor ventilation:
The driving force of this type of common plate flange ventilation duct is to use the centrifugal fan as the driving force to make the gas flow. The indoor ventilation of mechanical equipment is carried out according to the cooling of the air circulation workshop, and the common plate flange ventilation duct is to use the basic elements of indoor ventilation of mechanical equipment to carry out indoor ventilation.
The specifications, models and orientations of natural ventilation continue to change, and the expected target of indoor ventilation for natural ventilation is unstable. But it is not clear that natural ventilation does not consume electricity and energy, and it is a preventive measure for indoor ventilation for social and economic development. However, the indoor ventilation of mechanical equipment is not easily limited by natural conditions, and the air supply and exhaust system can be developed according to the needs to obtain stable indoor ventilation targets. Naturally, in some cases, mechanical indoor ventilation and natural ventilation can also be used.
