MSS SP-44 is a standard developed by the Manufacturers Standardization Society (MSS) of the Valve
and Fittings Industry. It provides specifications for steel pipeline flanges. Specifically, MSS SP-44 covers steel pipeline flanges for use in high-pressure, high-temperature services. These flanges are commonly used in the oil and gas, petrochemical, and power generation industries. ASME B16.47 incorporates the MSS SP-44 standard for large diameter flanges. ASME
B16.47 is a series of standards that cover large diameter steel flanges from NPS 26 through NPS 60. The series is divided into two classes: Series A and Series B. Both Series A and Series B flanges in ASME B16.47 reference the MSS SP-44 standard. Size Range: MSS SP-44 flanges
cover nominal pipe sizes (NPS) from 26 inches through 60 inches. These are considered large diameter flanges, suitable for heavy-duty applications. Pressure Classes: Series A: Class 150, Class 300, Class 400, Class 600, and Class 900. Series B: Class 75, Class 150, and Class 300. Design and Dimensions: MSS SP-44
