Concentric reducer

Concentric reducer is that its connection form is directly butt-welded to the steel pipe. The main manufacturing standards of concentric reducer are generally GB / T12459, GB / T13401, ASME B16.9, SH3408, SH3409, HG / T21635, HG / T21631, SY / T0510. Corresponding to concentric reducers are eccentric reducers, which are made of carbon steel, alloy steel and stainless steel.

There are two main international pipe 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 flange. In addition, there are Japanese JIS pipe flanges, but they are generally only used for public works in petrochemical plants, and have a small international impact. The pipe flanges of various countries are introduced below:

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 sleeve flange standards.

In summary, the internationally accepted standard for pipe 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. American tube flange system.

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