Flange forging is conducive to improving the utilization rate of metal due to the flange force generated in the metal under different rotation modes. The leakage of carbon steel flat welding flanges cannot be dealt with in a timely manner. Under moderate cleaning conditions, the leakage expands rapidly, causing material loss, damaging the production environment, and causing huge property losses.
Carbon steel flat welding flange leakage treatment
If a major safety accident occurs, the leakage of toxic and flammable media will lead to poisoning, fire or deflagration. Corrosion is an unavoidable leakage in the continuous production of carbon steel flat welding flanges in modern industry.
Corrosive media, temperature, resistance, vibration and other factors can cause leakage. The surface structure and specification deviation of the sealing material, the deterioration of the sealing parts, incorrect assembly and tightening can easily lead to leakage of the carbon steel flat welding flange.
In some traditional institutions, the way to leak carbon steel flat welding flanges is to use the sealing component together with the replacement sealant or to replace the pipe with the flange. However, this method of research has major limitations
In addition, some leaks are subject to work and life safety and health restrictions. Now we can use different polymer composite leakage agents, which is also an extremely important ideal method, especially in flammable environments, showing unique Advantage.
The problem of carbon steel flat welding flange has a great impact on the transportation pipeline. If there is a problem with the carbon steel flat welding flange, it may cause the entire pipeline to be paralyzed. Therefore, in daily pipeline operation, not only must timely inspection Its application also requires regular maintenance of carbon steel flat welding flanges.
If damage occurs, the flange must be repaired in time to ensure the reliability of the flange. Of course, if the carbon steel flat welding flange is stained, it also needs to be cleaned in time to avoid the carbon steel flat welding method. Blue produces corrosion.
Carbon steel flat welding flange sealing principle
In order to maintain a seal, a huge bolt force must be maintained, and for this purpose, the bolts must be made larger. Larger bolts must match larger nuts, which means that larger diameter bolts are needed to create conditions for tightening the nuts. However, the greater the diameter of the bolt, the flange will become more curved, the only way is to increase the wall thickness of the flange part.
The entire device would require great size and weight, which is a particular problem in offshore environments, where weight is always the main concern one has to pay attention to.
Moreover, fundamentally speaking, the flat weld flange is an ineffective seal. It requires 50% of the bolt load to squeeze the gasket, and only 50% of the load is used to maintain the pressure.
