We offer These Stainless Steel 347H Flanges as per DIN, ISO, JIS or ANSI Standard.
High-temperature resistance: Stainless steel 347H is designed for high-temperature applications. It offers excellent resistance to high temperatures and heat stability, making it suitable for use in areas where extreme temperatures are a concern.
Durability and longevity: Thanks to its durable construction and resistance to various corrosion elements, the stainless steel 347H flange provides exceptional durability. It can withstand harsh operating conditions without compromising performance, reducing maintenance requirements and long-term replacement costs.
Stability under welded conditions: Stainless steel 347H is stabilized with niobium, which provides intergranular corrosion resistance after exposure to temperatures in the sensitivity range during welding or other heating processes. This stabilization increases weldability and ensures the integrity of the flange in the welded state.
Creep Resistance: Stainless steel 347H exhibits better creep resistance at higher temperatures than standard austenitic stainless steel. This property is particularly well suited for applications involving constant high temperatures, such as petrochemical and refining industries.
Corrosion Resistance: One of the most important advantages of stainless steel, including 347H, is its corrosion resistance. These flanges are highly corrosion-resistant from various chemicals, acids and weather, ensuring durability and reliability in harsh environments.
Stainless Steel 347H 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.
Petrochemical Industry: Stainless steel 347H flanges are widely used in the petrochemical industry for piping systems, reactors, heat exchangers, and other equipment operating at high temperatures and in hot environments.
Power generation: Power plants, including conventional and nuclear plants, use stainless steel 347H flanges in steam turbines, boilers, heat exchangers, and other critical components. High resistance and creep of these flanges are essential to ensure reliable and efficient power generation systems.
Chemical applications: Stainless steel 347H flanges are used in pipes, vessels and equipment for handling volatile chemicals, solvents and acids in chemical plants. Their corrosion resistance and high-temperature stability make them ideal for maintaining system integrity and ensuring safety.
Maintenance Applications: Industrial applications of stainless steel 347H flanges in critical applications such as distillation columns, furnaces, and catalytic systems. These flanges withstand high temperatures and corrosive conditions during crude oil processing and processing of various petroleum products.
Understand operational requirements: Identify operating conditions, including temperature, pressure, water/air issues, corrosion potential and other environmental factors. This information will guide you in choosing flanges with the right materials, pressure references, and corrosion resistance.
Flange Dimensions and Standards: Specify the flange dimensions, including thickness, face type (e.g., raised face, flat face, ring type joint), and flange class or pressure rating (e.g., ANSI/ASME B16.5, ANSI ). /ASME B16) and 47 Series A or B). Ensure compatibility with existing pipeline components and adhere to industry standards.
Pressure and Temperature Ratings: Consider your application’s pressure and temperature requirements. Select flanges rated to handle maximum operating pressure and temperature conditions to ensure safe and reliable operation.
Accessories: Ensure the stainless steel 347H is compatible with the water or air piping. The material in the flange must also meet the requirements for chemical resistance, thermal stability and corrosion resistance in the intended environment.
