Why Choose Super Duplex Stainless Steel?

Super Duplex stainless steel is a blend of austenitic and ferritic grades, offering a perfect balance of mechanical strength and superior corrosion resistance. Its high molybdenum and chromium content ensures that these pipes resist pitting, stress corrosion cracking, and crevice corrosion, even in chloride-rich environments such as marine or chemical processing industries.

Advantages of Super Duplex SS Seamless Pipes (88.9mm X Sch 40):

  • Exceptional Strength:The dual-phase structure of Super Duplex makes these pipes twice as strong as conventional austenitic stainless steel grades.
  • Corrosion Resistance: : High resistance to chloride-induced stress corrosion cracking, pitting, and crevice corrosion.
  • Cost-Efficiency: : The enhanced durability and strength of Super Duplex reduce the need for thicker walls, even in heavy-duty applications.
  • High Pressure Handling: The Sch 40 rating indicates the pipe’s ability to handle moderate to high-pressure systems efficiently.

Manufacturing & Standards

Our Super Duplex SS seamless pipes (88.9mm X Sch 40) are manufactured to meet stringent international standards, such as:

  • ASTM A790/ ASME SA 790
  • UNS S32750 and S32760

At Alcona Tex Engineers, we ensure that every pipe undergoes rigorous testing for quality assurance, including hydrostatic tests, eddy current testing, and ultrasonic testing, ensuring that you get only the best material for your project.
