Standard System For Bent Pipes

There are two main international stainless steel flange standards, 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 only used in public projects in petrochemical plants and have little impact internationally. The following is an introduction to pipe flanges in various countries:

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

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

3. British and French pipe flange standards, each country has two casing flange standards.

The internationally accepted pipe flange standards can be summarized into two different and non-interchangeable pipe flange systems: one is the European pipe flange system represented by Germany; the other is the American pipe flange system represented by the United States. system.

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