Class 1500 Lap Joint Flange Dimensions in mm/kg

The ANSI / ASME B16.5 Class 1500 Lap Joint Flange is a type of flange used in high-pressure piping systems with a pressure rating of Class 1500, meaning it can withstand pressures up to 1500 pounds per square inch (PSI). This type of flange is typically used in conjunction with a stub end or a lap joint, and it is designed for applications where the piping system needs frequent disassembly or alignment.
