管路在我们的日常生活中四处由此可见，它确保了大城市管道网运输能力系统软件的一切正常运作，可是有没有人留意过，工程建筑排水管道应用的全是圆形管道，小编分享圆形风管和方形方管的区别。

Pipeline is everywhere in our daily life. It can be seen that it ensures the normal operation of the transportation capacity system software of the pipeline network in large cities. However, has anyone noticed that the drainage pipes of engineering buildings are all circular pipes, and the small series share the difference between circular air pipes and square square pipes.

圆形管道比正方形管路耐压工作能力更强

The pressure resistance of circular pipeline is stronger than that of square pipeline

自来水管是圆的关键考虑到的是工作压力，圆形管道耐压工作能力是要好于矩形方管的，自来水管在应用时，管中压力非常大，制成环形的受力匀称，所以能大限度的承受力。若制成正方形的，在斜角处更为欠缺，非常容易裂开。因此 自来水管、输油管及压缩空气管道全是采用圆钢管。而正方形管路因为耐压比不上环形管，非常少被应用在工作压力很大的管道上。

The water pipe is the key to the circle. Considering the working pressure, the pressure resistance of the circular pipe is better than that of the rectangular square pipe. When the water pipe is applied, the pressure in the pipe is very large, and the annular force is symmetrical, so it can bear the force to a great extent. If it is made into a square, it is more deficient at the oblique angle and is very easy to crack. Therefore, water pipes, oil pipes and compressed air pipes are all round steel pipes. Because the pressure resistance of square pipeline is not as good as that of annular pipeline, it is rarely used in pipelines with high working pressure.

正方形管路占有的高宽比和室内空间更小

Square pipe occupies less height width ratio and indoor space

在同样的截面下，矩形方管比环形管的高宽比要低，通风风管做为规格较大 的管道，布局在混凝土楼板内，必然要考虑到规模难题，通风风管越矮，占有楼高就越低，而且称为休重少的正方形通风风管，大多数全是提升横着总宽，降低高宽比来完成的，而环形通风风管一般出现在对容积规定没那麽严苛的场地，例如加工厂工业厂房，或是一些通风风管耐压很大的系统软件，因此 矩形方管相对而言也就更节约总面积。

Under the same section, the height width ratio of rectangular square duct is lower than that of annular duct. As a duct with larger specifications, the ventilation duct, which is arranged in the concrete floor, must take into account the scale problem. The shorter the ventilation duct, the lower the height of the building. Moreover, it is called square ventilation duct with less rest weight. Most of them are completed by raising the overall width of the cross section and reducing the height width ratio, The annular ventilation duct generally appears in sites with less stringent volume regulations, such as processing plants, industrial plants, or some system software with high pressure resistance of ventilation duct. Therefore, the rectangular square duct saves the total area relatively.

圆形管道比正方形管路密闭性更强

Circular pipes are more airtight than square pipes

圆形管道在运输液体时比正方形的越来越少出现盲区（依据轴向外扩散与反比例基本定律，若依照层.流测算，则正方形管路的四个角落里的水流量非常低），从而圆形管道更少出现液体停留造成的浸蚀和固定不动地基沉降、积垢。

When transporting liquid, circular pipes have less and less blind areas than square pipes (according to the basic law of axial outward diffusion and inverse proportion of square meters, if calculated according to layer and flow, the water flow in the four corners of square pipes is very low), so circular pipes have less erosion, settlement and scale of fixed foundation caused by liquid retention.

而通风管道，汽体水流量大，过风横断面大，不易出现固态颗粒地基沉降，即便 出现盲区还可以被髙速汽体带去，而且矩形方管的联接密封性规定不高，因此 矩形方管可以用在汽体运输上，而液体运输会造成 拐弯处的部分摩擦阻力大，进而提升离心水泵的水泵扬程，导致资源消耗。

In the ventilation duct, the steam water flow is large and the cross section of the air is large, so it is not easy to have solid particle foundation settlement. Even if there is a blind area, it can be taken away by the high-speed steam, and the connection tightness of the rectangular square pipe is not high. Therefore, the rectangular square pipe can be used in the transportation of steam, while the transportation of liquid will cause large friction resistance at the corners, which will increase the pump head of the centrifugal pump and lead to resource consumption.

正方形管路比圆形管道成本费更低

Square pipes cost less than circular pipes

正方形管路生产加工非常容易，价钱较低，便捷当场的生产加工和更新改造，而圆形管道需要加工厂预制构件，价钱较高，这也通常造成 了通风风管应用正方形管路。而在全部工程建筑成本预算中，绝大多数的状况下都是会应用矩形方管控制成本，这也是造成 通风风管应用正方形材料的较大 缘故。

Square pipes are very easy to produce and process with low price, which is convenient for on-the-spot production, processing and renewal. Circular pipes need prefabricated components from the processing plant, and the price is high, which usually leads to the application of square pipes in ventilation ducts. In the construction cost budget of all projects, rectangular square pipes will be used to control the cost in most cases, which is also the reason why square materials are used in ventilation ducts.
