Flat-welded flange is a kind of common component in pipeline engineering construction, because the flat-welded flange has many advantages in the use of links, so the application area is quite common, I firmly believe that everyone also has a lot of curiosity for flat-welded flange, so what are the characteristics of flat-welded flange? Let’s discuss it together
Characteristics of flat welded flange
Flat welded flange in the actual use of links, although there are relative advantages, but its defects are also quite prominent, due to some flaws in their own formulation, so the flat welded flange is difficult to ensure that it is not leaked in the case of connection.
The following are some defects in the development of flat welded flanges: The connection is dynamic, and regular loads such as thermal expansion and fluctuation will cause the operation of the middle surface of the flange, endanger the function of the flange, and then destroy the integrity of the flange, and then cause leakage.
Any product is unlikely to be unable to find defects, only to try to avoid manipulating the shortage of products at a low level, so in the production process of flat welded flange
As long as it is constantly improved, the characteristics of the flat welded flange can be reasonably improved, and the leakage can be avoided as far as possible, so that the flat welded flange plays a larger function in the welding.
The flat welded flange not only saves area and net weight, but also ensures that the connection head is impossible to leak, and has better sealing characteristics.
The tight construction causes the size of the flange itself to be reduced, and the diameter of the seal is also reduced. Second, the flange gasket has been replaced by a sealing ring to ensure the compatibility of the sealing surface.
In this way, the outer cover can be tightened with little pressure. As the required pressure is reduced, the size and number of bolts are also relatively reduced. And then develop a small body, light weight new products.
Therefore, the flat welded flange is a relatively high quality flange product, which reduces the quality and area, and plays an important function in industrial application.
Advantages of flat welded flange
The production of flat welded flange can save data and reduce costs. When the raw materials of the pipeline are special and the price is high, the flange welding cost of the same raw materials will be high
The use of this flange can effectively save material costs, conducive to construction, connection flange bolt hole is not convenient to align or avoid replacing the equipment flange bolt hole, this flat welding flange is very suitable for use.
It has excellent sealing function, the reason for the reduction of the size of the compact flange is the reduction of the diameter of the seal, which will reduce the cross section of the sealing surface.
In addition, flange gaskets have now been replaced by sealing rings to ensure an excellent match of flat welded flange seals facing the sealing surface.
