American standard EN1092-1 P245GH flange, The American standard flange has holes, and the two flanges are tightly connected with bolts. The flanges are sealed with gaskets. American standard flanges can be made by casting or threaded connection or welding.

American standard EN1092-1 P245GH flange, American standard flange connection is detachable connection. Two pipes, pipe fittings or equipment are respectively fixed on a flange plate, and a flange pad is added between the two flange plates, which are fastened together with bolts to complete the connection. American standard flange connection is an important connection method in pipeline construction. The new standard flange is easy to use and can withstand great pressure. Some pipe fittings and equipment comes with flange plate, which also belongs to flange connection.

American standard flange connection is widely used in industrial pipeline. At home, the pipe diameter is small, the pressure is low, and the flange connection is not visible. If you are in a boiler room or production site, pipes and equipment connected to flanges can be seen everywhere.

　　American standard EN1092-1 P245GH flange, The difference between American standard flange and national flange First, the pressure is different from the law: American standard pressure is weighing (category 150 pounds refers to 150 pounds of pressure, equivalent to PN2.0 pressure) Second, the standard caliber is called law, This is different: American standard is called inch, American standard flange is 2113 divided into American Society of Mechanical Engineers 16.5 and American Society of Mechanical Engineers 16.47. 5261 According to the 2009 edition of the Ministry of Chemical Industry standard, the national standard flange is divided into the European standard system and the American standard system, which are further revised and formulated with reference to the European and American flanges respectively.

　　American standard EN1092-1 P245GH flangeThe US system is the same as ASME flange, but there are still a large number of different data sizes, such as sealing 4102 face, flange neck, etc. In the 2009 edition, the national standard American flange and the American standard flange can hardly be cross-referenced, because individual pounds are 1653 grade.
