Characteristics and Application of High-Pressure Flanges
Published Time:

High-pressure flanges are flange products used in high-pressure pipelines, mainly made of stainless steel and alloy steel. However, carbon steel may also be used if the medium is common.
1. Applications of High-Pressure Flanges:
High-pressure flanges are flange products primarily used in high-pressure pipeline systems. They connect sections of the pipeline and are a crucial connection method in such systems, playing a vital role. They are mainly made of stainless steel. The connection involves attaching a high-pressure flange to each pipe or fitting, then bolting the two flanges together. A flange gasket is typically placed between the flanges to ensure a seal, achieving this through gasket deformation.
2. Characteristics of High-Pressure Flanges:
Given the environment in which high-pressure flanges operate, manufacturers are required to produce flanges with excellent wear resistance and corrosion resistance. Therefore, when using carbon steel high-pressure flanges, an anti-corrosion coating is usually required.
3. Wear Resistance of High-Pressure Flanges: Some high-pressure flanges require extremely high wear resistance, so we choose ceramic composite lining with an Al2O3 content greater than 95%, and a hardness of HV1000-1500. This provides superior wear resistance, more than ten times that of medium carbon steel, and even harder than tungsten steel;
4. Corrosion Resistance of High-Pressure Flanges: Corrosion resistance is another excellent characteristic of high-pressure flanges. High-pressure pipelines generally require resistance to corrosion, acids, alkalis, and salts, withstanding various inorganic acids, organic acids, and organic solvents. Their corrosion resistance is significantly better than that of typical stainless steel flanges. However, for large flanges and manholes, stainless steel is often preferred due to cost or inner diameter requirements.
