Prevent leakage and transportation of flat welded flange with neck
With neck flat welding flange in application due to the improper connection of stainless steel flange, perhaps the number of years of application is too long and show the leakage situation, show this kind of situation users do not need to panic
At this time, you need to check the location of leakage, usually due to the stainless steel flange connection clearance is very small, it is unlikely to introduce sealant according to the clearance to remove leakage.
The sealing process is tested on the spot according to the location of the leakage. In order to limit the plugging, the leakage point is composed of a sealing cavity under the stable fixture method, the sealant is introduced, and then the leakage is removed.
In order to prevent the potential leakage between the valve body and the stainless steel flange due to pressure holding, a ring cavity is set at the joint between the fixture and the stainless steel flange of the valve body.
When in use, after the sealant is dry and solid, according to the function research, part of the concentrated injection clamping is carried out, to prevent stress loosening, and then close the injection hole, which can be solved from the source, as long as there is no problem in transport, the problem will be solved
How to make the neck flat welding flange in the transport link does not change?
The appearance of flat welding flange with neck is relatively fragile, so transportation is a difficulty, which is also a problem for enterprises at present.
Once a user ordered 10 flanges with neck welding. Processing is processing out. But off the lathe, onto the truck. Once again, the problem arises.
The product the user wants has no water line and no bolt holes. It's a flat piece of merchandise. Enterprises and users to carry out communication, the user of this problem is also very headache, the size of some large, some small. The problem is that this type of neck flat welding flange is too thin. This problem, if it is such a transport, is difficult to prevent.
So we finally came up with a way, that is, when processing with steel bar cross fixed, the size of the neck flat welding flange stable, get the stability of the steel bar, the size will not change
And the user transport to the spot with a neck flat welding flange on the electric welding equipment, and then remove the bar. And the position of the welding steel bar is polished.
The above method is to analyze and improve the problems that will occur during transportation, so as to ensure that the product is not damaged and the purpose of the product itself is not destroyed
