Galvanized Flanges Galvanized flanges are essential components used in piping systems to connect pipes, valves, pumps, and other equipment. These flanges are crafted from steel that has undergone a galvanization process, wherein a protective zinc coating is applied to the surface.
The galvanization process involves either hot-dipping the steel flanges in molten zinc or utilizing an electroplating method to apply a zinc layer. This protective coating serves to shield the steel from corrosion, making it highly resistant to rust and other forms of deterioration caused by exposure to moisture, chemicals, or harsh environmental conditions.
Galvanized flanges are crucial components used in piping systems across various industries due to their corrosion-resistant properties and suitability for demanding environments.
Galvanized flanges find extensive use in applications where pipes or equipment are exposed to outdoor elements, moisture, or corrosive substances. Industries such as construction, water treatment plants, chemical processing, oil and gas, and marine environments often utilize galvanized flanges to ensure the longevity and integrity of their piping systems.
