What are Lap Joint Flanges?
Joint Flanges are two-piece flange assemblies used together with a stub end. Unlike welded flanges, the flange itself is not directly welded to the pipe, allowing it to rotate freely for easy bolt alignment. These flanges are ideal for systems requiring regular dismantling, inspection, or maintenance.
They are commonly used in low-pressure piping systems and industries where corrosion resistance and flexibility are essential.
