Carbon steel flanges differ in strength between different USES

Flanges of different strength will show different characteristics and advantages in use.Carbon steel flanges have different hardness and strength in use and production.The carbon steel flanges with different materials can give play to different advantages and characteristics in utilization.Flange connection is probably necessary to withstand high tensile, compressive, torsion, shear strength, according to certain production examples and essentials, for sealing pipe plug.Carbon steel flange in the production of the necessary differences and production configuration of production, flange cover production data are as follows: carbon steel flange is not in the middle of the hole flange.The envelop can generally perform well in performance and advantages. The production should be carried out strictly in accordance with the definite process and key points.Carbon steel flange is the better choice.When you put in the right amount of carbon, it becomes solid.It can play a different role and cost in utilization.The flange is the connecting device of two large diameter pipes, and the carbon steel flange is the flange made of carbon steel.

Especially when the acceptance of the soft gasket, carbon steel flange surface coarse degree of shadow, for example, turning the flange surface grain is spiral, use metal gasket, if coarse degree value is bigger, gasket can't plugging knife lines formed by the death of the spiral groove, pressure, medium will follow the showing to the groove.The soft sealing gasket has a much lower requirement for the smooth and clean level of flanged surface, because it is easy to deform, and can probably block the dead machining blade, thus preventing leakage.For the soft gasket, the flanged surface is too smooth, but it is unfavorable, because at this time, the interface leakage resistance decreases, so that the gasket difference, the required flanged surface roughness is not the same.

The required gaskets are also different.Smooth surface flanges are normally used only for low pressure, carbon steel flanges.Flange situation is different.Soft thin sealing gasket;Under high pressure, smooth face flanges can also be used if the flanges are sufficiently strong, but thick soft gaskets should be used, probably with wound gaskets with inner reinforcing rings or reinforcing rings.This kind of place, metal gasket also is not practical, because at this time the pressure that asks is too big, bring about bolt bigger deformation, make flange not easy seal.If metal gaskets are to be used, the smooth surface should be reduced to reduce the area of battle with the gaskets.In this way, the compression stress of narrow smooth surface will increase under the condition that the bolt tension is similar.
