Lap joint stub ends are used in piping systems where flange rotation, convenient alignment, and simplified maintenance are important. They are commonly installed with lap joint flanges in systems that require frequent dismantling or use corrosion-resistant piping materials. The appropriate stub end and flange combination depends on pressure, temperature, fluid compatibility, material grade, and applicable piping standards.
