Manufacturing & Quality Standards
Our flanges are forged from high-quality steel billets to ensure uniform grain flow and optimal mechanical stability. Flange faces are machined with a standard phonographic finish (serrated finish) to maximize gasket seating and prevent leaks. All flanges are clearly marked with size, rating, material heat code, and manufacturing standard.
