通风管道工程常见的风管材质

来源:http://www.jnqsg.com/     发布时间:2021-06-18  

随着技术进步,人们对暖通空调工程品质要求相应提高,通风管道工程的洁净要求和设备材料的节约要求也逐步提高;通风管道工程常见的风管材质主要有镀锌不锈钢风管、不锈钢不锈钢风管以及复合不锈钢风管。我们来简单了解一下:
With the progress of technology, people's requirements for the quality of HVAC engineering are correspondingly improved, and the requirements for the cleanliness of ventilation pipeline engineering and the saving of equipment and materials are also gradually improved; The common duct materials of ventilation duct engineering mainly include galvanized stainless steel duct, stainless steel duct and composite stainless steel duct. Let's take a brief look:
不锈钢风管质量较好,适用性强,但价 格高。目前市场上较广的不锈钢风管是镀锌板的。镀锌板不锈钢风管,基本是不锈钢不锈钢风管的特性,但是价 格相对只有不锈钢风管的三分之二甚更低。
The quality of stainless steel air duct is good, the applicability is strong, but the price is high. At present, the stainless steel air duct widely used in the market is galvanized sheet. Galvanized stainless steel duct is basically the characteristics of stainless steel duct, but the price is only two-thirds or even lower than that of stainless steel duct.
不锈钢风管主要是在风管铁皮上镀上一层锌,对铁皮起到保护的作用。锌镀层经钝化处理、染色或涂覆护光剂后,能显著提高其防护性和装饰性。
The stainless steel air duct is mainly plated with a layer of zinc on the iron sheet of the air duct to protect the iron sheet. The protective and decorative properties of zinc coating can be significantly improved after passivation, dyeing or coating with light protecting agent.
复合不锈钢风管一般应用在外界环境较为普通,对风管要求不太高的场所。由于铁皮容易在各种环境下发生化学反应,造成腐蚀、生锈。而锌在干燥的空气中几乎不发生变化。通风管道工程在潮湿的空气中,锌表面会生成致密的碱式碳酸锌膜。
Composite stainless steel air duct is generally used in the place where the external environment is common and the requirements for air duct are not too high. Because the iron sheet is easy to have chemical reaction in various environments, causing corrosion and rust. Zinc is almost unchanged in dry air. Dense basic zinc carbonate film will be formed on the surface of zinc in humid air.
在济南通风管道加工工程施工时选择的通风管是可以用白铁制作的,通风风管分圆型和矩形两种,可根据用户的不一样需求出产各种形状、各种规格型号的通风管道。
In the construction of Jinan ventilation pipe processing project, the selected ventilation pipe can be made of white iron. The ventilation pipe can be divided into round type and rectangular type. According to the different needs of users, various shapes, specifications and models of ventilation pipes can be produced.
白铁做通风管道的方形弯头容易些,先画出扇形,把雄的咬缝做好后量下2条曲线的长,和方管的另一边,就成2块曲面料的尺寸,当然不要忘加咬缝余量,如做大的方管,可先在地上放扇形,各条线尽可能放长,画好后覆上白铁皮拓样就比较方便,也省料。在实践中公式意义不大,有时需要求证放样的精度会用一点。建议买本怎样画展开图的书看。
It's easier to make square elbow of ventilation duct with white iron. First, draw a fan. After the male seam is finished, measure the length of the two curves and the other side of the square tube to form the size of two curved fabrics. Of course, don't forget to add the seam allowance. For example, for large square tube, first put a fan on the ground, and each line should be as long as possible. After drawing, it's more convenient to cover with white iron sheet. In practice, the formula is of little significance. Sometimes it is necessary to verify the accuracy of lofting. It is suggested to buy a book on how to draw unfolded drawings.
白铁之所以备用做通风管道,与它自身优异的性质是分不开的,因为白铁表面含有锌层,所以管道的性质比较稳定,可以防止油水的侵蚀,从而保护管道的质量,而且白铁是不会生锈的,所以美观性也很好,白铁表面比较光滑,作为管道使用,表面的杂质会比较少,在餐厅使用可以保证餐厅的美观性,而且表面也不会有油污的残留物,所以不会影响餐厅的美观性。而且白铁的价 格比较便宜,质量较轻,安装的时候比较简单。
The reason why white iron can be used as ventilation pipe is inseparable from its excellent properties. Because the surface of white iron contains zinc layer, the property of the pipe is relatively stable, which can prevent the erosion of oil and water, so as to protect the quality of the pipe. Moreover, white iron will not rust, so its beauty is also very good. The surface of white iron is relatively smooth, and there will be less impurities on the surface when it is used as a pipe, In the restaurant can ensure the beauty of the restaurant, and the surface will not have oily residue, so it will not affect the beauty of the restaurant. Moreover, the price of white iron is relatively cheap, the quality is relatively light, and the installation is relatively simple.
