ANSI B16.5 Blank Flanges

Our range of forged blank flanges to ASME B16.5:2017 can be found below, this includes pressure class 150 & 300 flanges in sizes 1/2″ (DN15) – 24″ (DN600). All of our ASME/ANSI B16.5 blank flanges are made of black (self-colour) carbon steel to ASTM A105.
All of these blank flanges, also known as blind flanges come with a raised sealing face, this increases pressure on the gasket for a tighter seal, they’re also available with 3.1 test certificates for full traceability. This type of pipe flange is most often used to cap or blank off the end of a pipeline.
