STEEL WELDED NECK FLANGES include many types of standards and material. If according to standard to divide, which refer to ASME/ANSI B16.5, DIN AND JIS. If according to material to divide, which refer to carbon steel, stainless steel and alloy steel. And flanges also have many kinds of pressure.  ASME B16.5 CARBON STEEL WELDED NECK FLANGES CLASS 1500 Is just one kind of high pressure flange.
