Wn Flange

The international pipe flange standard mainly has two systems, namely the European pipe flange system represented by German DIN (including the former Soviet Union) and the American pipe flange system represented by American ANSI pipe flange. In addition, there are Japanese JIS pipe flanges, but in petrochemical installations generally only used for public works, and the international impact is small. The pipe flanges of various countries are introduced below: 1, to Germany and the former Soviet Union as the representative of the European system pipe flange 2. American system pipe flanges, represented by ANSI B16.5 and ANSI B 16.47 3, British and French pipe flange standards, two countries each have two pipe flange standards. To sum up, the international standard of pipe flanges can be summarized as two different and not interchangeable pipe flange systems: a European pipe flange system represented by Germany; Another is the American pipe flange system represented by the United States.

Due to the transition structure of conical neck and butt welding connection, the strength and stiffness of the flange are strengthened, and the sealing performance is better than that of the flat welding flange. The disadvantage is the need to use forgings manufacturing, consumption of materials, manufacturing costs. Suitable for high pressure, high temperature or high sealing requirements.
