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.

在不銹鋼風管安裝的過程中，偶爾會因為操作不當或者環境受限，出現不銹鋼風管變形的情況，出現這樣的問題怎么解決呢？

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?

，打樣。尤其針對形狀復雜的配件時，提前在不銹鋼板上劃線下料，避免出現返工和變形的情況。

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，減少人工操作。人工錘擊板材，極容易變形。但是才有剪切、折邊、咬口的機械來加工，就會精確很多。正規的加工廠都會配有的機械設備下料加工。

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，按順序焊接。在焊接風管時盡量均勻受熱或冷卻，減少變形。組對焊接時，先用夾具固定在焊接，以免變形。

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.

總之，加工是巧活，不僅需要有較強的邏輯思維和空間想象力，還需要對材質、設備有足夠的了解。通過科學的設備和知識，結合我們的細心、耐心，盡量減少變形的可能。同時，我們要有強烈的責任心，畢竟通風工程是一項非常重要的工作，要做好和外界交換空氣的橋梁作用，同時也能在一定程度上，維護人們的身體健康。

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.
