Concentric ReducerL Butt Weld Steel Pipe Fittings Reducer ASME/ANIS B16.9 BW Pipe Fitting
The size heads whose center is on a straight line are called concentric size heads. The commonly used forming process is reducing diameter pressing, expanding diameter pressing or reducing diameter plus expanding diameter pressing, and stamping forming can also be used for reducing diameter pipes of certain specifications.
Product Usage
Petroleum gas pipeline engineering, natural gas pipeline engineering, chemical plants, power plants, shipyards, pharmaceuticals, dairy products, beer, beverages, water conservancy, etc.
Standard System
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.
