What are the materials of carbon steel flanges?

The butt welding flange is not easy to deform, has good sealing, and is widely used. It has corresponding rigidity and elasticity requirements and reasonable butt welding thinning transition. The distance between the welding port and the joint surface is large, and the joint surface is free from welding temperature deformation.

It adopts a relatively complicated trumpet-shaped structure suitable for pipelines with large fluctuations in pressure or temperature or high-temperature, high-pressure and low-temperature pipelines. It is generally used for the connection of pipelines and valves with PN greater than PN; it is also used for pipelines that transport expensive, flammable and explosive media.

Pipes and equipment connected by carbon steel flanges can be seen everywhere.

The American standard flange is exactly the same as the ASME flange, but there are still a lot of different data sizes, such as sealing surface, flange neck and so on. In the 2009 version, the national standard American flange and the American standard flange can hardly be referred to each other because of individual pound classes. The American standard flange is suitable for the connection of carbon steel pipes whose nominal pressure does not exceed.

The sealing surface of the American standard flange can be made into three types: smooth type, concave-convex type and tongue-and-groove type.
The stainless steel flange is very convenient and quick in the process of installation and disassembly. Therefore, it has a very good application for the replacement of the pipeline or the disassembly and inspection of the pipeline, so that the pipeline can get better sealing performance.

The chromium element in the stainless steel flange has the function of increasing the electrode potential of the iron-based solid solution and has the function of passivating iron, which is beneficial to promote the anti-corrosion effect of stainless steel. Stainless steel flanges can also be called flanges or flanges, etc., when connecting pipes.

The flange connection plays an important role and value, but it is necessary to ensure that the nominal pressure is within a certain range in use. Product function of Q345R container flange: wear resistance: the content of Al2O3 in the lining ceramic layer of ceramic composite steel pipe is more than 95%, and the microhardness is HV1000 to 1500, so it has extremely high wear resistance, and its wear resistance is higher than that after quenching.

Medium carbon steel is more than ten times higher than tungsten carbide.

Corrosion-resistant ceramics are neutral materials with stable chemical properties, good corrosion resistance and acid resistance, and can resist various inorganic acids, organic acids, organic solvents, etc., and their corrosion resistance is more than ten times that of stainless steel.
Elite forged flat flange manufacturers focus on high-quality goods and never waver in quality. While continuously providing product production technology, we continue to strengthen and improve product quality assurance systems in the production process of products, and strictly control every link in the production process. , Strict quality inspection is carried out for each product that leaves the factory.
