Precision-machined sealing surface on forged steel flanges for leak-proof connections in high-pressure industrial piping systems.
The sealing face is a critical component of forged steel flanges, consisting of a precisely machined surface that interfaces with gaskets to create a leak-proof seal in high-pressure, high-temperature piping systems. This component ensures the integrity of fluid or gas containment by providing uniform compression and surface contact with mating flanges, preventing leakage and maintaining system pressure.

The three primary types are Raised Face (RF) for general applications, Flat Face (FF) for low-pressure systems, and Ring Type Joint (RTJ) for high-pressure/high-temperature applications requiring metal-to-metal seals.
Surface finish (typically 125-250 Ra) directly impacts gasket compression and seal integrity. Too smooth surfaces may cause gasket slippage, while too rough surfaces can damage gaskets and create leakage paths.
