People who have learned about carbon steel flanges know that there are many casting steps. In terms of its material, carbon steel is also different from some actual steel, and its performance is better than the performance of actual steel.
Therefore, a good flange is mostly made of carbon steel, in fact, the carbon steel flange, carbon steel in addition to carbon generally includes a little silicon, manganese, sulfur, phosphorus and other substances, are in terms of material has its unique
The particularity of carbon steel flange
The material of carbon steel flange is carbon steel, and we can know that the anti-rust effect of carbon steel is not so excellent, and it is easy to be deeply corroded by external causes, which affects the process performance of carbon steel flange.
Therefore, the carbon steel flange must be put into use after some anti-rust treatment during production. The common anti-rust treatment is mainly divided into gold plating layer or brush anti-rust paint.
The area used by the carbon steel flange is relatively special, so the material required is as smooth as possible, tensile, compressive, torsion and other characteristics, it can be used in a high pressure environment is not easy to distort the change.
Because the carbon steel itself has very little raw edge, its friction is not very large, and it can be used more efficiently in the equipment.
In addition, carbon steel flanges should strictly comply with national or relevant industry standards to manufacture, remember not to use unqualified materials to make, nor can you be fake and inferior in size, this loophole approach will also lead to substandard substandard products, will also cause failure to the entire flange system, Even caused property economic losses and casualties of this kind of safety accidents occurred.
Carbon steel flange pay attention
Carbon steel does not specifically add alloy elements of steel, stainless steel is in order to prevent rust and add high alloy content of steel. Stainless steel is far more expensive than carbon steel. These two kinds of steel use is not the same, can not be compared to good or bad, carbon steel is usually higher strength than stainless steel, but easy to rust
Large carbon steel flanges should play an important role and value in use and construction according to certain conditions and environment and the use characteristics and advantages of carbon steel flanges for different use environments. If the use is not good, it is easy to cause the flange produced by the flange manufacturer to break.
In pipeline engineering, flat welding flange is mainly used for pipeline connection, high pressure flange for butt welding flange due to the need of pressure capacity, with easy deformation, good sealing performance, wide range of application characteristics.
The flange has a relatively complex flared structure, which is characterized by stiffness and elasticity in the corresponding requirements, reasonable butt welding thinning transition, weld away from the joint surface.
