What is Lap Joint Flanges?

Lap joint flanges are a type of flange used in plumbing systems to make it easier to assemble, disassemble, and align pipes. They have two major components: the stub end and the backing flange. The stub end of the pipe is welded, and the backing flange is bolted to the piping system. This property makes them especially suitable in situations where piping component alignment is crucial, such as pipelines with expansion joints or systems undergoing thermal expansion and contraction.

Lap joint flanges are widely utilised in sectors such as oil and gas, chemical processing, water treatment, and power generation, where dependable connections and ease of maintenance are required. Overall, lap joint flanges are a practical solution for connecting pipes and equipment in piping systems, enabling flexibility, ease of assembly, and dependability in a variety of industrial applications.
