ANSI/ASME B16.5 CLASS 600 WELDING NECK FLANGE is one size of weld neck flange.  Weld neck flange can be produced with the size range from 1/2” to 60” according to different international standards. The material mainly refer to carbon steel, stainless steel, and alloy steel. The production processing generally is forging, so it is also called forged flange. Weld neck flange has two designs, one is common type the other one is long type. The common type is used with pipeline, the long type is not suitable for pipeline and is used for manufacturer.  
ASME B16.5 CLASS 600 WELDING NECK FLANGE
Weld neck flange belongs to one type of pipe flange. They are widely used in industries because of their long tapered hub is easy welded to the pipes. One point is very important, the hub must be matched with the wall thickness of pipes. So specifying the schedule of pipes is quite necessary . Weld neck flange is often used in high pressure pipes. These flanges are ideal for extreme fluctuations of temperature and in environments where there may be a lot of bending and handling of the flanges.
