09MnNiD Alloy Steel Flange, Low Temperature Steel Flange, 09MnNiD Forged Flange, 09MnNiD Butt Welding Flange

09MnNiD low temperature alloy steel flat welded ring plate loose flange blind flange model is complete Liangfeng pipe fittings high pressure alloy butt welding flange, ring connection flange and other flanges are mainly used in the connection and installation of pipelines. This flange The most important connection method in pipeline construction is mainly to connect the bridge between the pipe and the pipe. The blue pads are fastened together with bolts so that the connection is completed. Since the nominal diameter of the butt-welded flange of the vessel cylinder is different from the specific size represented by the nominal diameter of the pipe, the dimensions of the stainless steel flange and the stainless steel butt-welded flange of the vessel with the same nominal diameter are also different. Cannot substitute for each other. Under normal circumstances, the butt welding flange is always divided into several arc segments for processing: 1. First, the blank is forged into a square billet, and then cold-formed into an arc segment. After annealing and stress relief heat treatment, it is assembled into a whole circle on the vertical lathe Processed to the designed shape and size; 2. Transported to the construction site, and then welded several arc sections into a complete special-shaped butt-welded flange and assembled with the pressure vessel; 3. Butt-welded flanges are different in use and production According to the corresponding standards, the production and use of special-shaped stainless steel flanges can be used in actual use value and function; 4. Butt welding flanges are used as sealing and fastening connectors for large-scale aerospace, petroleum, chemical and other fields. There are a wide range of applications in containers.

The American standard flange connection is a detachable connection. It is to fix two pipes, pipe fittings or equipment on a flange plate respectively, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection. American standard flange connection is an important connection method for pipeline construction. The new standard flange connection is easy to use and can withstand greater pressure. Some pipe fittings and equipment have their own flange, which is also a flange connection.

Blind board
In industrial pipelines, American standard flange connections are widely used. In the home, the pipe diameter is small and the pressure is low, and the flange connection is not visible. If in a boiler room or production site, flanged pipes and equipment can be seen everywhere.
