In the manufacturing of steel plates, the application of carbon steel flanges is crucial and widespread. The steel plates must undergo ultrasonic testing to ensure there are no delamination defects. They should be cut into strips along the rolling direction of the steel, then bent and welded to form circular rings, ensuring that the surface of the steel forms a cylindrical shape. It is important to note that steel plates should not be directly machined into necked flanges, and butt welds must be fully penetrated to ensure the strength and sealing of the welds.
The design of carbon steel flanges is compact and simple, making maintenance relatively convenient. Their sealing and spherical surfaces usually remain in a closed state, which makes them less susceptible to erosion by the medium. Carbon steel flanges are suitable for a variety of working media, such as solvents, acids, water, and natural gas, and typically exhibit good corrosion resistance and durability.
When using carbon steel flanges, carbon steel bolts do not necessarily require the addition of insulating gaskets and sleeves. Insulating gaskets and sleeves are primarily used in situations where the system may carry electrical current or where the fluid within the pipeline is flammable or explosive. Even in such cases, if stainless steel bolts are selected, insulating gaskets and sleeves must also be added for enhanced safety and protection.
Overall, carbon steel flanges play a significant role in steel plate manufacturing and pipeline systems due to their stability, ease of operation, and low maintenance cost. They are well-suited for systems that transport common working media.
