Check ANSI B16.5 Steel Pipe Flanges, Steel Pipe Flanges Dimensions in mm.


ASME B16.5 Flange belongs to the B16.5 standard which covers pipe fittings of ¼ inches to 24 inches in diameter. R.C. Metal Corporation is a manufacturer and supplier of these ANSI B16.5 Steel Pipe Flanges and other material made flanges in various types and dimensions. The different materials, the different types and the different Steel Pipe Flanges Dimensions are suited for varying applications. The physical, mechanical and chemical properties vary depending on the ASME B16.5 Flange Material. The stainless steel materials are the most used to manufacturing different types, sizes, pressure classes and specifications of the ASME B16.5 Standard pipe flanges.


ASME B16.5 Flange

ASME B16.5 Flange

There are other materials such as commercially pure materials, high alloys, steel alloys, carbon steels and others as well. The Flange Standard B16 5 can have different types of faces. There are flat face, raised face and ring type joint flanges in this standard. In applications which require high toughness and wear and tear resistance, the Carbon Steel ANSI B16.5 Pipe Flanges are used. The materials have high hardness and toughness compared to ordinary stainless steels so the Carbon Steel ANSI B16.5 Flanges are used in outdoor applications, exposed pipe lines and other wear and tear prone applications.
