Standard system of flanges
Mar 28, 2018

There are two main international standards for pipe flanges, 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 flanges. In addition, there are Japanese JIS pipe flanges, but they are generally used only for public works in petrochemical plants, and they have a smaller international impact. Now introduce the flanges of each country in the following:

1. European system pipe flange represented by Germany and the former Soviet Union

2. American system pipe flange standard, represented by ANSI B16.5 and ANSI B 16.47

3, the United Kingdom and France pipe flange standards, the two countries have two casing flange standards.

In summary, the internationally accepted standards for pipe flanges can be summed up in two different and non-interchangeable pipe flange systems: a European pipe flange system represented by Germany; the other is represented by the United States. American pipe flange system.

IOS7005-1 is a standard promulgated by the International Organization for Standardization in 1992. It is actually a pipe flange standard formed by merging two series of pipe flanges from the United States and Germany.
