The question about the advantages of this feature of flat welding flange is still a topic that we pay more attention to, it is related to the company and the enterprise’s product cost or economic benefits and other questions, so the sealing principle of flat welding flange in continuous improvement and sound. As everyone knows, the key to the development of flat welding flange is that it can not guarantee no leakage.
The advantages of this feature of flat welded flange
This is the lack of its formulation: the connection is dynamic, such as thermal expansion, and changing the unstable term load will cause the movement between the flange faces, interfere with the function of the flange, and then make the integrity of the flange damage, resulting in leakage.
Any commodity is unlikely not to have a lack of, just as far as possible to control the lack of goods to less, so the company in the production of flat welding flange as far as possible to improve the characteristics of the product, so that it plays a better function.
The tightness principle of flat welding flange is that the tight surface of the bolt compresses the gasket with each other and produces tightness, but it also causes tightness damage at this time. In order to maintain tightness, you have to maintain huge bolt interactions, so the bolts need to be larger.
Larger bolts need to be paired with larger nuts, which means that larger-diameter bolts must take advantage of tightening the nut.
However, the larger the diameter of the bolt, the available flange will appear bent, the only way is to expand the wall thickness of the flange.
The overall device of flat welding flange is the largest size and net weight
which becomes a special question in the natural environment, because in this case, the net weight is still a key question that we must pay attention to.
Moreover, from the source, the flat welded flange is a kind of useless sealing, it must use a 50 bolt load to squeeze the gasket, and to maintain the pressure of the load only 50.
Flat welded flange is widely used in every field, it is the first to connect the pipeline responsibility, has been the pipeline road engineering of the general pro-lai and after several years of continuous discussion in the material has been quite great improvement and get rid of, let the flat welded flange open a higher level
