Flanges 

Flange refer to the various designs and configurations of flanges, which are mechanical components used to connect pipes, valves, pumps, or other equipment in piping systems. Common types include weld neck flanges (for high-pressure applications), slip-on flanges (easy to install for low-pressure systems), socket weld flanges (for small-diameter high-pressure systems), blind flanges (to close pipe ends), lap joint flanges (for systems with frequent dismantling), and threaded flanges (for non-welded connections). Each type is selected based on application requirements like pressure, temperature, and installation ease.
