As a crucial component in pipeline connections, carbon steel flanges play a key role in industrial applications according to their excellent value and outstanding mechanical performance.
Carbon steel flange refers to steel with a carbon content less than 2% and generally does not contain a large amount of alloying elements. It is sometimes also called mild carbon steel or plain carbon steel.
During the production process, carbon steel flanges undergo a series of processes to ensure quality and reliability. For example, the steel plate should undergo ultrasonic testing to eliminate laminar defects. After being cut into strips, they are bent and welded to form a circular ring, with the surface becoming a smooth cylinder. In terms of butt welding, a fully penetrated weld is often used to achieve better connection results.
As for the choice of bolts, for general carbon steel flanges, it is not necessary to add insulating gaskets and sleeves. These insulating gaskets and sleeves are mainly used in situations where there may be electricity or where the fluid inside the pipeline is flammable and explosive. Even if stainless steel bolts are chosen, insulating gaskets and sleeves need to be added to provide insulation.
