American ANSI B16.5 carbon steel A694 F42 F46 F52 F56 F60 F65 F70 raised face forged steel flange sliding

AEA Socket Weld Flanges are typically used on smaller sizes of high pressure pipes. These flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. RAW MATERIAL LISTNO.Material GradeCategoryNO.
