In this article, we will discuss the benefits and features of Stainless Steel Super Duplex Flanges!

 

Stainless Steel Super Duplex Flanges

 

Our Super Duplex 2507 flanges, made of a stainless steel alloy with 25% chromium, 4% molybdenum, and 7% nickel, are known for their high strength and excellent resistance to localized corrosion caused by chloride. This alloy is popularly used for its yield strength, which is double that of annealed austenitic stainless steels such as 304 and 316 stainless.

The microstructure of this alloy in the annealed state contains roughly 40-50 percent ferrite. Despite possessing the corrosion resistance properties of austenitic grades, the microstructure of super duplex steel imparts the superior strength of the ferritic grades. Thus, it is a viable solution for combating chloride-induced stress cracking. Moreover, this type of steel exhibits excellent resistance to sulfide-stress corrosion cracking under sour gas conditions.

 

Features of Stainless Steel Super Duplex Flanges:

 

Stainless Steel Super Duplex Flanges have several features that make them ideal for a variety of applications:

• High strength
• High resistance to pitting, crevice corrosion resistance
• High resistance to stress corrosion cracking, corrosion fatigue, and erosion
• Excellent resistance to chloride stress-corrosion cracking
• High thermal conductivity
• Low coefficient of thermal expansion
• Good sulfide stress corrosion resistance
• Low thermal expansion and higher heat conductivity than austenitic steels
• Good workability and weldability
• High energy absorption

 

Benefits of Stainless Steel Duplex Flanges

 

The benefits of stainless steel super duplex flanges are numerous, and here are some of the most important ones:

• High Durability - Super duplex flanges are known for their high strength and durability. They can withstand extreme pressure and temperature, making them ideal for heavy-duty applications.

 

• Corrosion Resistance - Stainless steel super duplex flanges have a high resistance to corrosion, making them ideal for use in harsh environments. They are resistant to pitting, crevice corrosion, and stress corrosion cracking.

 

• Cost-Effective - Despite their high strength and durability, super duplex flanges are cost-effective. They have a longer lifespan than other types of flanges, which means that they do not need to be replaced as frequently.

 

• Versatility - Super duplex flanges are versatile and can be used in a wide range of applications. They are commonly used in the oil and gas, chemical, and petrochemical industries, as well as in offshore and marine applications.

At Vishal Tubes Industries, we pride ourselves on providing our clients with high-quality stainless steel super duplex flanges that meet their unique requirements. Our flanges are available in various sizes, dimensions, and specifications, and we can also manufacture custom flanges to meet your specific needs.
