Process flow of high-pressure flange

The process flow of the high-pressure flange

The advantage of the high-pressure flange is that it has good seam sealing performance and a long time. However, if the welding torch joint is not properly controlled, cracks will occur. The operating principle of the flange is to use the electrical insulation function of the insulating gasket in the flange and the insulating sleeve gasket with good strength, and the electrical insulation at both ends of the flange is used for operation. However, due to the change in the demand of the petroleum natural growth gas industry, the shortcomings of flanges are exposed from time to time. About general corrosive medium, acid resistant asbestos board is commonly used

High pressure flange has a large machining allowance, but its tools are simple and versatile, so it is widely used to forge single piece and small batch forgings with simple shape. Carbon steel flange, high pressure flange, butt welding flange and large diameter flange free forging equipment include air hammer, steam air hammer and hydraulic press, which are suitable for the production of small, medium and large forgings. High pressure flat welding flange manufacturers, large diameter flange die forging productivity is good, simple operation, simple completion of mechanization and automation. Die forgings have good dimensional accuracy, small machining allowance, and reasonable fiber structure distribution of forgings, which can further improve the service life of parts

The elbow made by the cold extrusion process of the inner and outer die is selected as the high-pressure flange, which has beautiful appearance, uniform wall thickness and small scale error. One of the early manufacturers of flanges, marine flanges, carbon steel flanges, Japanese standard flanges, German standard flanges, flat welding flanges, pipeline components and series products in China. It will definitely affect the progress of the project, covering an area of 135000 square meters. The Russian standard flange shall be marked according to the nominal diameter, nominal pressure, sealing surface method code, steel pipe series code and specification number. Examples of high pressure alloy flange symbols: the convex face welded steel pipe flange with nominal diameter of 80mm and nominal pressure of 4.0MPa (25bar) (equipped with metric pipe)
