SS welded pipes grade Super Duplex Diameter 50.8 mm X Sch 10

SS welded pipes grade Super Duplex Diameter 50.8 mm X Sch 10, Suppliers & Exporters in India.

Super Duplex stainless steel is a high-performance alloy that combines the best features of both austenitic and ferritic stainless steels. With a balanced microstructure of approximately 50% austenite and 50% ferrite, Super Duplex provides exceptional strength and corrosion resistance. It is particularly effective in harsh environments, making it suitable for various applications, including chemical processing, oil and gas, and marine industries.

SS welded pipes made from Super Duplex stainless steel with a diameter of 50.8 mm and Schedule 10 specifications are a robust solution for demanding applications. Their superior corrosion resistance, high strength, and versatility make them an ideal choice for industries that require reliability in harsh conditions. As technology continues to evolve, these pipes will remain at the forefront of material selection for critical applications.

Specifications of SS Welded Pipes

  • Diameter:50.8 mm (2 inches)
  • Schedule: 10
  • Material:Super Duplex Stainless Steel (commonly designated as UNS S32750 or UNS S32760)

Key Features

  • Corrosion Resistance:Super Duplex pipes offer superior resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich environments.
  • High Strength: These pipes exhibit impressive mechanical properties, making them suitable for high-pressure applications.
  • Weldability: Although Super Duplex stainless steel can be challenging to weld, advancements in welding technology and techniques have made it feasible to produce high-quality welded joints without compromising corrosion resistance.
  • Durability:The combination of austenitic and ferritic phases enhances toughness and durability, even at elevated temperatures.

Applications

  • Oil and Gas Industry: Used for pipelines and fittings in offshore and onshore facilities where corrosion resistance is crucial.
  • Chemical Processing: Ideal for handling aggressive chemicals, including acids and chlorides.
  • Marine Applications: Used in seawater applications, such as heat exchangers and desalination plants, due to its ability to withstand harsh marine environments.

Benefits of Using 50.8 mm X Sch 10 Super Duplex Pipes

  • Cost-Effectiveness: While the initial cost may be higher than standard stainless steel, the long-term savings due to reduced maintenance and replacement costs can make Super Duplex pipes a more economical choice over time.
  • Reduced Weight: Schedule 10 pipes have thinner walls compared to heavier schedules, which reduces weight and makes handling and installation easier
  • Versatile:Suitable for various applications due to its strength and resistance properties, offering flexibility in design and engineering.
