High-pressure flange

High pressure flange, suitable for connection and sealing of high-pressure pipelines.

High Pressure Flange: Flange used for pipeline or equipment connection with pressure higher than 10MPa.

As a classification of flanges, high-pressure flanges are also mainly used in pipeline installation. High-pressure flange connection is an important connection method for pipeline construction, mainly connecting pipes and pipes. The high-pressure flange connection is to fix two pipes, pipe fittings or equipment on a flange respectively, add flange gaskets between the two flanges, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment have their own flanges, which are also flange connections.

Product performance of high-pressure flanges

1. Wear resistance: The Al2O3 content in the inner ceramic layer of the ceramic composite steel pipe is greater than 95%, and the microhardness is HV1000-1500, so it has extremely high wear resistance, and its wear resistance is ten higher than that of the quenched medium carbon steel. More than times, better than tungsten carbide.

2. Corrosion resistance ceramics are neutral materials with stable chemical properties, excellent corrosion resistance and acid resistance, resistance to various inorganic acids, organic acids, organic solvents, etc., and their corrosion resistance is more than ten times that of stainless steel.

High pressure flanges features

1. Sealing method: The core of the high-pressure self-tightening flange is a unique, new metal-to-metal seal, which relies on the elastic deformation of the sealing lip (T-shaped arm) of the sealing ring to form a seal, which is a hard seal; The joints, ferrules, and seal rings combine to form a strong rigid body, which makes the strength of the connection part far greater than the strength of the pipe base material itself. When under pressure, the ribs and lips play the role of strength and sealing respectively, which can not only self-tighten and seal, but also strengthen the pipeline, which greatly strengthens the overall strength of the connection part

2. Tensile resistance: In most cases, the high-pressure self-tightening flange in the connection can withstand tensile load better than the pipeline itself; destructive tests prove that the flange is still intact and leak-free after the pipeline fails to bear the tensile load.

3. Anti-bending performance: A large number of tests show that this flange will not leak or loosen when subjected to large bending loads. Actual test: DN15 high-pressure self-tightening flange welded to the pipeline has undergone many cold bends. The high-pressure self-tightening flange connection does not leak, and the bolts are not loose.

4. Compression resistance: In normal pipeline applications, high-pressure self-tightening flanges will not be subjected to overload compression; when a higher compressive load occurs, the maximum load on the high-pressure self-tightening flange is determined by the ultimate strength of the pipeline Sure.

5.Impact resistance: The geometric size is small and compact, which can withstand the impact that traditional high-pressure flange cannot withstand; the unique metal-to-metal sealing structure greatly enhances its impact resistance.

6. Corrosion resistance: Different materials are selected so that the corrosion resistance can meet the special anti-corrosion requirements of different use environments.
