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.

ASME B16.5 CARBON STEEL WELDED NECK FLANGES CLASS 1500, the standard is ASME B16.5 or ANSI B16.5, the material is carbon steel ASTM A105, the form is welded neck, class 1500 is the pressure. So it also can be called ANSI B16.5 flange, carbon steel A105 flange, welded/ welding neck flange 1500class. Because its high pressure, many power plant, chemical plant and shipbuilding plant make it used for special places. Flange plays a very important role in the whole project, if the quality is not enough good big risk will be left in the project. Our flanges are under inspection of third party (SGS), the quality is guaranteed. Choosing us choosing safe. Welcome your inquiry at any time.
