In all the flanges, some of them will be deformed during use, so what is the cause of the deformation of this product? The first is the shortage of materials in the production of products, many materials will be deformed after heating, and some materials will be deformed under high pressure.
The cause of Faran’s deformation
In the process of use of this product, it will cause its deformation for various reasons, so when customers buy such products, they should first pay attention to its product materials, not only need to make the material have sufficient strength, but also need to see whether it can maintain balance under temperature.
There will also be some flange deformation due to the manufacturer’s production process can not do, in the production of this product, whether it is for the molding process, but also for its surface treatment technology is needed to meet the corresponding needs
If the manufacturer’s process is not in place, it will naturally cause the quality of the product to decline significantly, which may lead to its deformation in use.
Of course, different products will also have a great difference in the deformation time, such as some products will be deformed after installation, and some will be deformed after use for a period of time.
Of course, there will be some flanges due to aging in the process of use and deformation, some aging is due to the lack of the product itself, and some aging is due to the medium
For example, under the high will form some scale outside the product, and the corrosion of this scale will eventually make it deformed, further useless, and this requires the environmental resistance and anti-aging degree of the product to improve, but this requires the manufacturer to improve the material and process at the same time.
What do you need to pay attention to when connecting flanges
When using welding technology, the current passing through should not be too large. Under normal circumstances, it must be 20% less than the electrode, and the arc should not be too long when operating.
So that the rapid cooling between layers can be adopted narrow pass technology. It is only necessary to prevent the above mentioned situation, and the stainless steel welded flange will prevent corrosion.
The electrode used should be kept clean. If necessary, it is recommended to use drying methods to push the electrode dry. As everyone knows, here, stainless steel flange manufacturers should pay special attention to the drying method can not be recycled to have a good drying state to prevent gas shedding.
Stainless steel flange manufacturers should pay attention to is that chromium stainless steel using the flat welding method, there will be a large hardening standard, easy to crack. If the same electrode is used for welding, the required preliminary work is to preheat and cold treatment, and the use of flange welding methods.
