01 How are MSS SP-44 flanges different from other flange standards?

MSS SP-44 flanges are distinguished by their higher pressure ratings compared to other standards like ANSI B16.5. They are designed to withstand more severe service conditions.
These flanges are commonly used in industries such as oil and gas, petrochemicals, power generation, and other industries where high pressures and temperatures are encountered.
MSS SP-44 covers weld-neck flanges, blind flanges, and socket-welding flanges. These flanges are typically used in high-pressure applications.
