Product Description

Large Diameter Flat Plate:
Flat flange, also known as flat welded flange, is a connection method that directly welds the flange on the end of the pipe, which is widely used in the industrial field.
Structural characteristics
Flange: usually round, the diameter is determined according to the size of the connected pipe, and a number of bolt holes are evenly distributed above for installing bolts to achieve tight connection.
Sealing surface: The common sealing surface form has plane (FF), sudden surface (RF) and so on. The surface sealing surface is simple in structure and easy to process, but the sealing performance is relatively weak, and it is suitable for the working conditions of low pressure and non-toxic and harmless medium. A convex sealing surface is added on the basis of the plane, which has good sealing performance and is suitable for medium and low pressure conditions.
Welding groove: In order to ensure the quality of welding, the welded end of the flat welding flange is usually designed with welding groove, groove form and size vary according to the welding method and pipe material, common V shape, U shape and so on.

Manufacturing process
Raw material selection: carbon steel, stainless steel, alloy steel and other materials are generally selected, and the quality and performance of raw materials directly affect the quality and service life of flat welded flanges.
Forging or casting: blank manufacturing methods are mainly forging and casting. The forging process can improve the mechanical properties of the material and make the flange have better strength and toughness, but the cost is relatively high. The casting process has high production efficiency and low cost, but the internal quality of the product is relatively poor.
Machining: After the blank is forged or cast, it is necessary to carry out a series of machining such as turning, milling, drilling, etc., to achieve the specified size and accuracy requirements, and strictly control the process parameters during the processing to ensure the dimensional accuracy and surface quality of the flange.
Heat treatment: In order to improve the mechanical properties and structure of the flat welded flange, improve its corrosion resistance and fatigue strength, it is usually necessary to carry out annealing, normalizing, quenching and tempering heat treatment.
Pressure grade: Common pressure grades are PN0.25MPa, PN0.6MPa, PN1.0MPa, PN1.6MPa, PN2.5MPa, PN4.0MPa, etc., which should be selected according to the working pressure, medium characteristics and temperature of the pipeline system.
Size specifications: According to the nominal diameter (DN) and nominal pressure (PN) of the pipeline to determine, the national standard for its size DN5000 below the plate can be produced
