ASME B16.9 Stub End Stainless Steel Stub End Pipe Fittings are buttweld fittings that can be used in combination with a lap joint flange. Alternatively the ASME B 16.9 Stub End can be used with welding neck flanges to make flanged connections. The use of Lap Joint Stub End has two advantages. One , the ANSI B 16.9 Stub End can reduce the total cost of flanged joints when used in a piping system in high material grades. This is because the lap joint flange does not need to be of the same material of the pipe while the Stub Ends B16.9 but could be a lower grade.
