Flange machining, we must first understand the inside a parts of itself in the process of welding is likely to have some defects, stainless steel flange weld defects, if more severe, then basically is to use manual mechanical grinding, the grinding way used to make amends, relatively is likely to produce a series of grinding marks, may be more or less will cause uneven surface, which directly affects the whole equipment is beautiful.
Flange processing time may be fine polishing the uneven, so on a series of pickling passivation process, the area is larger artifacts, it is difficult to achieve a more uniform processing effect, so if can't achieve this effect, so in the process of processing will take more time, relatively for some auxiliary material of the cost of materials is also very high.
In the process of processing is also facing a problem, may have some scratches, flange above these scratches are very difficult to remove, so at the time of whole passivation, under the condition of corrosive medium, tends to occur a series of chemical corrosion, to produce some rust.
So, once these problems occur in the process of flange processing, how should we solve them? First of all, we should pay attention to the selection of materials. We should choose different materials according to different conditions.
