Stainless Steel Large Diameter Flanges are specially designed flanges used for large-scale piping systems, typically ranging from DN600 (24") and above, and extending to several meters depending on project requirements.
Manufactured from high-quality stainless steel, these flanges provide excellent corrosion resistance, strength, and durability, making them ideal for demanding environments such as offshore, chemical processing, and water treatment systems.
They are commonly produced using plate cutting, ring rolling, or fabrication methods, especially when standard forging is not practical for large sizes.
