The ANSI / ASME B16.5 Class 2500 Slip-On Flange is a type of flange designed for high-pressure applications, adhering to the ASME B16.5 standard with a pressure rating of Class 2500. It is called a Slip-On Flange because it is designed to slip over the pipe and is then welded at both the inner and outer edges to create a secure connection.
