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.
Slip-on weld flanges have no internal stop. Slide a pipe through the flange and weld on both sides.
