90 degree stainless steel elbow is one of the widely used pipe connection elements at present, which is mainly used for the connection between pipes, so as to improve the patency degree between pipes. However, many users do not know much about the relevant knowledge. The following is a brief introduction:

I. 90 degree stainless steel elbow classification:

1. Carbon steel, stainless steel, alloy steel, copper, etc.

2. According to the production method, it can be divided into pushing, pressing, forging, casting, etc.

3. According to the manufacturing standard, it can be divided into national standard, petrochemical standard, chemical standard, American standard, German standard, Japanese standard and Russian standard.

4. According to its radius of curvature, it can be divided into long radius 90 degree stainless steel elbow and short radius 90 degree stainless steel elbow.Long radius 90 degree stainless steel elbow refers to its radius of curvature is equal to 1.5 times the outside diameter of the pipe, that is, R=1.5D.A short radius 90 degree stainless steel elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R= 1.0d.(D is the diameter of the 90 degree stainless steel elbow, and R is the radius of curvature).

5. According to the pressure levels, there are about 17 kinds, which are the same as the American pipe standards, including Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s and XS.Sch80, SCH100, Sch120, Sch140, Sch160, XXS;The two most commonly used are STD and XS.
