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

Divided by production method
Divided into national standard, electric standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.
Divided into a long radius elbow and a short radius elbow by the radius of curvature. A long radius elbow refers to the outer diameter of a tube whose radius of curvature is equal to 1.5 times, that is, R = 1.5D; a short radius elbow refers to a radius of curvature equal to the outer diameter of the tube, that is, R = 1.0D. (D is the elbow diameter and R is the radius of curvature). 5. According to the pressure level: about seventeen, and the United States pipe standards are the same: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH100, Sch120, Sch140, Sch160, XXS; the most commonly used are STD and XS.
standard system
There are two main systems for the international pipe flange standard, namely the European pipe flange system represented by German DIN (including the former Soviet Union) and the American pipe flange system represented by the 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 little impact internationally. Now introduce the national pipe flanges as follows:
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, British and French pipe flange standards, the two countries have two casing flange standards.
In summary, the internationally accepted pipe flange standard can be summarized as two different, 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. This standard is actually a standard for pipe flanges that combines two series of pipe flanges from the United States and Germany.
