Technical notes
- Flanges may be cast, forged, or plate (for blind flanges only) materials.
- Requirements and recommendations regarding bolting and gaskets are also included.
- The American Society of Mechanical Engineers issues standards for mechanical and piping design.
- ASME standard B16.47 covers large diameter pipes up to a 60-inch bore.
- ASME standard B16.7 series A flanges are equivalent to MSS SP44 flanges.
- ASME standard B16.7 series B matches API 605 flanges.
- The Standard is limited to flanges and flanged fittings made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forged, or plate materials.
- Also included in this Standard are requirements and recommendations regarding flange bolting, flange gaskets, and flange joints.
- API Standards API flanges are designed to handle very high pressures and temperatures.
- API flanges have a smaller bolt circle than MSS flanges.
- API flange standards start with a number followed by a letter.
- API standard 17D is the specification for sub-sea well head flanges.
- "The Differents Between API and ANSI Flanges" The difference between ASME/ANSI and API flanges is the fabrication material and the higher rated API operating pressure.
- ASME/ANSI flanges are common in industrial process systems handling water, steam, air and gas.
- API flanges are manufactured for high strength operating refinery systems with products such as oil and explosive gases.
- The flange standards API 6A and ASME/ANSI B16.5 are similar dimensionally - but the API 6A flanges are rated for higher pressures as shown in the table below: API vs.
- MSS Standards MSS flange standards were adopted by American National Standards Institute.
- MSS flange standards start with an SP followed by a number.
