Product Overview: Lapped Flange
A lapped flange is a specialized flange lap joint stub end type used in piping systems where two lap joint flanges are mated with a gasket sandwiched between, forming a secure and leak-proof junction. Compared to standard flanges, lapped flange connections offer enhanced flexibility, ease of alignment, and fitment in systems where pipe sections may require frequent disassembly or rotation. This attribute makes lapped flange assemblies a go-to choice in industries demanding reliability and dynamic maintenance cycles.
