ASME B16.9 Stainless Steel 304/316 Butt Weld Pipe Fittings Eccentric Reducer Pipe Fittings Reducer

The eccentric size head refers to the size head whose circle center is not on the same straight line. Its function is to stick the pipeline to the wall or to the ground without occupying space, and it is to connect two pipes of different diameters to change the flow rate.

standard system

National Standard, American Standard (ANIS), Japanese Standard (JIS), British Standard (BS), German Standard (DIN), Italian Standard (UNI), etc.

International pipe flange standards mainly have 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 flanges. In addition, there are Japanese JIS pipe flanges, but they are generally only used in public works in petrochemical plants, and they have little international impact. Now the introduction of pipe flanges in various countries is as follows:

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 of the two countries has two casing flange standards.

In summary, the internationally universal pipe flange standards 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 represented by the United States American pipe flange system.

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