SS 347 flanges are widely used in the chemical and petrochemical industry due to their exceptional corrosion resistance. They provide excellent protection against oxidation, as well as outstanding weldability. They also have a high tensile strength at both normal and elevated temperatures, making them ideal for use in steam conditions. SS 347 flanges are also resistant to general corrosion, stress-corrosion cracking, pitting attack from chloride solutions, crevice corrosion and intergranular attack. These features make them an excellent choice for many applications, including pressure vessels, valves, pumps and piping systems exposed to corrosive media within the chemical/petrochemical processing industry.
What are SS 347 Flanges?
SS 347 Flanges are stainless steel flanges made from chromium, nickel, and columbium alloys. These materials provide excellent corrosion resistance and good mechanical properties allowing them to be used in many industrial applications. In addition, the alloying elements impart good formability and weldability, making it easy to fabricate and install these flanges in existing pipelines. SS 347 flanges offer superior oxidation resistance even at high temperatures allowing for safe operation up to 870°C (1600°F). Furthermore, these flanges are resistant to intergranular corrosion, making them suitable for operations involving strong reducing acids such as sulfuric acid. Overall, SS 347 flanges are a great option for use in acidic environments or high-temperature applications due to their combination of features, including superior strength and durability.
Benefits of SS 347 Flanges
Corrosion Resistance
One of the main benefits of SS 347 flanges is their corrosion resistance. The high level of chromium and nickel in the alloy creates a protective layer over the surface of the flange, preventing rust and corrosion. This property is especially important in the chemical and petrochemical industry, where aggressive chemicals and fluids constantly flow through the pipes. SS 347 flanges are ideal for applications that require excellent corrosion resistance.
High-Temperature Resistance
SS 347 flanges are also known for their high-temperature resistance. The alloy contains niobium, stabilising the material at high temperatures, up to 1600°F (871°C). This property makes SS 347 flanges suitable for high-temperature applications, such as steam lines, boilers, and heat exchangers. It also prevents the flanges from becoming brittle and prone to cracking when exposed to heat.
Oxidation Resistance
Another benefit of SS 347 flanges is their excellent oxidation resistance. The alloy contains a small amount of titanium, which reacts with oxygen to form a protective oxide layer. This layer prevents the flange from rusting when exposed to air or oxygen-rich environments. SS 347 flanges are commonly used in applications that require oxidation resistance, such as food processing, pharmaceuticals, and aerospace.
Applications in the Chemical and Petrochemical Industry
Stainless Steel 347 Flanges are widely utilized in the chemical and petrochemical industries due to their excellent corrosion resistance, toughness and stability at high temperatures. These flanges offer superior resistance to serious corrosive environments in chemical processing and oil & gas production. Furthermore, they offer superior protection against oxidation, which helps maintain product purity for longer-lasting results. Additionally, these flanges provide shock & vibration absorption, ensuring that liquid transfers are done without any interruption or damage while protecting from temperature fluctuations. Overall, stainless steel 347 flanges provide an attractive solution for many applications in the chemical and petrochemical industries.
