Could you help explain the meaning of each word in the description of the flange below?

FLANGE WN SCH10S B16.5 BE/RF CL 150 A182-F304 . .
WN butt weld flanges SCH10S and the pipe designation for pipes welded to flanges: S denotes stainless steel; the dimension standard is B16.5, the American standard specifies a BE/RF bevel end/convex face design, with a pressure class of CL 150, which is equivalent to 2.0mpa per the Chinese standard, using material A182-F304.
A182-F304 304 stainless steel
Basically correct. As a supplement, WN stands for welding neck, which refers to butt-welded fittings with a neck; the second and third points are correct. The BE/RF joint surface should be convex, and CL150 is correct. A182 refers to ASTM A182, which is a standard in the American standards system; it pertains to forged or rolled alloy and stainless steel pipe flanges, forged fittings, as well as valves and parts designed for high-temperature service. F304 denotes the material type, namely forged stainless steel F304
Doesn’t SCH10S refer to the wall thickness grade of the pipe connected to the flange?
I also learned that – it turns out I only knew the dimensions and that CL150 means 150 pounds
