Carbon steel flanges have different hardness and strength in use and production, so it can probably play an important role and cost in use. Carbon steel flanges made of different materials can give play to different advantages and characteristics in use. Low carbon steel has good plasticity and low strength. It is probably necessary for flange connection to suffer from high tensile, compressive, torsional and shear strength. It should be used according to certain manufacturing examples and essentials for sealing pipe plugs. The carbon steel flange shall be produced according to the necessary different data and production configuration. The production data of the flange cover are as follows: the carbon steel flange is a flange without holes in the middle. It is guaranteed that good performance and advantages can be achieved, and production shall be carried out strictly according to the confirmed process and essentials. Carbon steel flange is a better choice. It will become firm after adding proper amount of carbon element. It may play a different role and cost in utilization.

The shims required are also different. Flat face flange is usually only used for low pressure and carbon steel flange. The situation of flanges is different. Equipped with soft thin gasket; Under high pressure, if the strength of the flange is sufficient, the flat face flange can also be used, but thick soft gasket should be used, probably a wound gasket with inner reinforcing ring or reinforcing ring. In such places, metal gaskets are also not practical, because the required compression force is too large at this time, resulting in large deformation of the bolt, making it difficult to seal the flange. If metal gasket is used, the smooth surface shall be reduced to reduce the fighting area with the gasket. In this way, when the bolt tension is the same, the compression stress of the narrowed flat surface will increase.
