When processing large-diameter flanges, we must first understand that such a component itself may have certain defects in the welding process. If the welding defects of stainless steel flanges are serious, they are basically Manual grinding is used for grinding. This grinding method is used to make up for it. Relatively speaking, a series of grinding marks may be produced, which may cause uneven surface more or less, which directly affects the entire equipment. Beautiful!

When large-diameter flanges are processed, it may be unevenly polished, so in a series of pickling and passivation processes, it is difficult to achieve a relatively uniform treatment effect for workpieces with a relatively large area. Therefore, it is said that If this effect cannot be achieved, then it will definitely take more time in the process of processing, and relatively speaking, the material consumption for some auxiliary materials is also very high!

There is also a problem in the process of processing. There may be some scratches on the flange. These scratches are very difficult to remove. Therefore, during the overall passivation, under the conditions of corrosive media, there are often scratches. A series of chemical corrosion occurs, resulting in some rust.

So, once these problems occur during the processing of large-diameter flanges, how should they be solved? First of all, we must pay attention when selecting materials, choose different materials according to different situations, and then make sure that they are processed in the correct way.
