Long-neck weld flanges have a square-cut end for welding directly to a pressure vessel or tank. With a longer neck than butt-weld flanges, they stick out farther from your tank wall for easier access to bolts. These flanges eliminate the need to weld a flange to a length of pipe.
Forged flanges have better strength than cast flanges. 304 stainless steel flanges offer very good corrosion resistance, and 316 stainless steel flanges have excellent corrosion resistance.

Low-Pressure Steel Unthreaded Pipe Flanges
Bolt two flat-surface flanges or two raised-surface flanges of the same size together with a gasket (sold separately) to create an access point in a pipe line. Flanges are for use with low-pressure applications in noncorrosive environments.
Long-neck weld flanges have a square-cut end for welding directly to a pressure vessel or tank. With a longer neck than butt-weld flanges, they stick out farther from your tank wall for easier access to bolts. These flanges eliminate the need to weld a flange to a length of pipe.
