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.
