Export flange: what is the standard system for flanges?
For the international standards of pipe outlet flanges, there are mainly two systems, one is the European pipe flange system represented by German DIN (including the former Soviet Union), and the other is the American pipe flange system represented by ANSI and American ANSI. In addition, Japan also has JIS pipe flanges, but they are generally only used for public works in petrochemical plants, and have little impact internationally.

The following is an overview of the export flanges of various countries:
1. The European pipe flange system represented by Germany and the former Soviet Union.
2. American pipe flange system standards represented by ANSIB16.5 and ANSIB16.47.
3. British and French pipe flange standards, each country has two sleeve flange standards.
In a word, the international general specifications on pipe outlet flanges can be summarized as two different and non-interchangeable pipe flange systems: one is the European pipe flange system represented by Germany; the other is the United States as the Representative of the American pipe flange system. ISO7005-1 is a standard issued by ISO1992. It is actually a pipe flange standard composed of two sleeve outlet flanges from the United States and Germany.
