厂房、车间越来越多，很多需要在密闭的环境中工作，甚洁净室中完成。有些产品在生产和加工的过程中，甚会产生有害气体，威胁工人的身体健康。所以，厂房通风工程成为建厂必备工作。所以，现在的工艺排气系统、溶剂排气系统、有机排气系统、废气排气系统及普通排气系统室外部分、湿热排气系统、排烟除尘系统等气密性要求较高的地方会安装不锈钢风管。同时，不锈钢风管的材质特殊，采用的一般是SUS304、316、303、310、310S、301、302、304L、316L 、321、201、202、902、904、317、430等材质，既能耐腐蚀、耐热、还具备高强度的物理特性。
There are more and more workshops, many of which need to work in a closed environment, even in a clean room. In the process of production and processing, some products may even produce harmful gases, threatening the health of workers. Therefore, plant ventilation project has become a necessary work for plant construction. Therefore, the current process exhaust system, solvent exhaust system, organic exhaust system, exhaust gas exhaust system and the outdoor part of the general exhaust system, wet and hot exhaust system, smoke exhaust and dust removal system and other places with high air tightness requirements will be installed with stainless steel air ducts. At the same time, the stainless steel air duct is made of special materials, such as SUS304, 316, 303, 310, 310S, 301, 302, 304L, 316L, 321, 201, 202, 902, 904, 317, 430, which can resist corrosion, heat and have high strength physical properties.
在不锈钢风管安装的过程中，偶尔会因为操作不当或者环境受限，出现不锈钢风管变形的情况，出现这样的问题怎么解决呢？
During the installation of stainless steel air duct, the stainless steel air duct will occasionally be deformed due to improper operation or limited environment. How to solve such problems?
，打样。尤其针对形状复杂的配件时，提前在不锈钢板上划线下料，避免出现返工和变形的情况。
First, proofing. Especially for the parts with complex shapes, the stainless steel plate shall be marked in advance to avoid rework and deformation.
其次，减少人工操作。人工锤击板材，极容易变形。但是才有剪切、折边、咬口的机械来加工，就会精确很多。正规的加工厂都会配有的机械设备下料加工。
Secondly, reduce manual operation. The plate is easily deformed due to manual hammering. However, the machine for cutting, folding and seaming will be much more accurate. Regular processing plants will be equipped with professional mechanical equipment for blanking processing.
然后，按顺序焊接。在焊接风管时尽量均匀受热或冷却，减少变形。组对焊接时，先用夹具固定在焊接，以免变形。
Then, weld in sequence. During the welding of air ducts, they shall be heated or cooled as evenly as possible to reduce deformation. When assembling and welding, first fix the fixture on the welding to avoid deformation.
总之，加工是巧活，不仅需要有较强的逻辑思维和空间想象力，还需要对材质、设备有足够的了解。通过科学的设备和知识，结合我们的细心、耐心，尽量减少变形的可能。同时，我们要有强烈的责任心，毕竟通风工程是一项非常重要的工作，要做好和外界交换空气的桥梁作用，同时也能在一定程度上，维护人们的身体健康。
In a word, processing is flexible, which requires not only strong logical thinking and spatial imagination, but also sufficient understanding of materials and equipment. Through scientific equipment and knowledge, combined with our care and patience, the possibility of deformation is minimized. At the same time, we should have a strong sense of responsibility. After all, ventilation engineering is a very important work. We should do a good job as a bridge to exchange air with the outside world, and at the same time, it can also maintain people's health to a certain extent.
