We offer These Stainless Steel 904L Flanges as per DIN, ISO, JIS or ANSI Standard.
Exceptional corrosion resistance: Stainless steel 904L is known for its outstanding corrosion resistance, especially in highly corrosive environments such as sulfuric acid, chloride, and other aggressive elements. This makes 904L flanges ideal for infrastructure deterioration, a major concern.
Formability and Machinability: Stainless steel 904L is extremely easy to fabricate and machine, allowing complex flange structures with specific shapes. This increases the flexibility of the 904L flange to meet the project’s specific requirements.
Versatility: The 904L flange is versatile and can be used in a wide range of applications in a variety of industries, including chemical processing, oil and gas, chemical and desalination plants
Durability and longevity: Stainless steel 904L flanges exhibit excellent strength and longevity due to corrosion resistance and rugged mechanical properties. They can withstand harsh working conditions and require little maintenance during their lifetime.
High Temperature Resistance: These flanges retain their mechanical properties and corrosion resistance even at elevated temperatures, making them suitable for high-temperature applications such as chemical processing and petrochemical industries
Stainless Steel 904L Flanges shave excellent mechanical qualities and are resistant to wear corrosion, and high temperatures, they are widely used in various industries. These flanges are widely used in the oil and gas, petrochemical, power generation, and aerospace industries. They play an important part in joining equipment, valves, and pipe systems. They are perfect for applications exposed to severe operating conditions, such as high temperatures, high pressures, and corrosive environments, because of their exceptional strength, toughness, and wear resistance.
Chemical applications: In the chemical industry, 904L flanges are used in pipelines, reactors and storage applications where resistance to corrosive chemicals such as sulfuric acid, phosphoric acid, and chloride solutions is important
Desalination plants: Stainless steel 904L flanges play an important role in desalination plants where they are used in seawater transport, brine processing and water treatment, providing excellent corrosion resistance to salinity places
Petrochemical Industry: These flanges are used in petrochemical plants to connect piping and storage equipment containing volatile chemicals and high temperatures to ensure reliable operation and safety wom
Oil & Gas Industry: Stainless steel 904L flanges are used on offshore platforms, refineries and pipelines, providing superior corrosion resistance in seawater, brine environments and acidic environments encountered during exploration, production and refining processes
Corrosion Resistance: Determine the specific corrosive conditions in which the flanges will operate. Stainless steel 904L is known for exceptional corrosion resistance, especially in high-temperature environments containing sulfuric acid, chloride, and other aggressive elements. Ensure that flanges are suitable for corrosion conditions at their intended design.
End connections: Select flanges with end connections that meet the needs of your piping system, such as raised faces, flat faces, or ring-type joints (RTJ). Make sure flanges and faces are properly aligned and sealed to prevent leaks and maintain system integrity.
Flange Type and Size: Based on the needs of your piping system, determine the appropriate flange type (e.g., weld neck, slip-on, socket weld, threaded) and size. Consider factors such as pipe size, pressure rating, and compatibility with existing materials.
Temperature and Pressure Analysis: Consider your application’s temperature and pressure requirements. The stainless steel 904L flange is designed to withstand high temperatures and pressures, but it is important to ensure that the flange you choose meets your system’s specific operating conditions.
