ASME/ANSI B16.5 Class 600 SO

Pipe flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification.

The Slip-on flange has a low hub because the pipe slips into the flange prior to welding. It is welded both inside and out to provide sufficient strength and prevent leakage.Slip-on flanges are all bored slightly larger than the O.D. of the pipe.
