Highly skilled manpower is required for the fabrication of welding neck flanges. Where imperial flanges are detailed, the dimensions have been converted to the nearest mm Here are some of the different ANSI Flange sizes and specifications: Size: ANSI Flanges come in a range of sizes from 1/2 inch toinches.

The size of the flange is determined by the nominal diameter of the pipe to which it is attached. Pressure rating: ANSI Flanges are rated for different pressure levels, ranging from to The However, Weld Neck flanges (Fig) are expensive as compared to other flange types.
