When the plates are arranged and arranged, the air ducts are parallel in pairs, and the opposite plates are not equal in length and width. When the blanking is opened, the edges and corners of the plates shall be connected, and the length, width and diagonal of each plate shall be checked to make its error within the allowable range; After blanking, the two plates opposite to the air duct shall overlap to check the dimensional accuracy. Otherwise, the force on the air duct connection will be uneven, the air duct will be uneven after installation, the flange gasket will be loose, and the system will leak, causing air conditioning load loss and extending the service life.

完善通風管的加工工藝，不同的產品在加工工藝上是不同的，完工后的質量是完全不同的，所以完善產品的加工工藝對我們大有裨益。只有你在整體的加工工藝上不斷的提升，完工后質量上就能夠有更好的保障，這個方面對我們今后更好的使用產品來說是有較大的保障的。

Improve the processing technology of the vent pipe. Different products have different processing technologies, and the quality after completion is completely different. Therefore, improving the processing technology of the products is of great benefit to us. Only if you continue to improve the overall processing technology, the quality will be better guaranteed after the completion of the project, which is a greater guarantee for our better use of the product in the future.

不銹鋼風管之前是為了船舶的通風，以及空調系統中的換氣等。之后逐漸擴展，現在在火車、地鐵、建筑等這些行業中，以及一些民用設施中都有應用。所以越來越多生產廠家也非常重視。如果不是一些環境要求需要的話，不用在在不銹鋼風管上鍍鋅。因為，不銹鋼具有良好的耐腐蝕性。而對普通鐵皮也是很重要的，因為鐵皮容易生銹腐蝕。

Stainless steel air duct is used for ship ventilation and air exchange in air conditioning system. After that, it has been gradually expanded, and now it is used in such industries as trains, subways, buildings, and some civil facilities. Therefore, more and more manufacturers attach great importance to it. If it is not required by some environmental requirements, it is not necessary to galvanize the stainless steel air duct. Because stainless steel has good corrosion resistance. It is also important for ordinary iron sheet, because it is easy to rust and corrode.
