Super Duplex Steel Pipes Tubes

Super Duplex Pipes and Super Duplex Tubes for Corrosion-Resistant Applications

Piyush Steel is a leading stainless steel pipe manufacturers in India. We manufacture Super Duplex Pipes and Super Duplex Tubes from raw materials tested for chemical composition and mechanical strength before production begins. They have a two-phase microstructure of almost equal ferrite and austenite, and this gives them a higher pitting resistance than the normal austenitic grades. PREN values >40 are superior to 316L stainless steel in chloride-rich environments. Its corrosion resistance makes super duplex tubes ideal for offshore and marine service, and its 550 MPa yield strength allows thinner walls and lower costs. Super duplex pipes are used in oil, gas, chemical, food, pulp, pollution control, and agrochemical industries in seamless and welded forms.

FAQs

What are super duplex pipes used for? +

Super duplex pipes are highly resistant to pitting and are used in acid transfer lines, seawater cooling systems and sour gas lines in oil, gas, marine and chemical processing plants.

What are the benefits of super duplex tubes? +

Super duplex tubes deliver PREN ratings above 40, yield strength near 550 MPa, and resistance to stress corrosion cracking in chloride service under sustained load.

What grades of super duplex pipes are available? +

Piyush Steel is a manufacturer of super duplex pipes in UNS S32750 & S32760 under ASTM A790 for Seamless and ASTM A928 for welded pipe.

What sizes and specifications are available for super duplex pipes? +

Super duplex pipes ship from NPS ½ to NPS 24, with wall thickness from 1.2 mm to 40 mm, in standard schedules 5S through XXS.

How do super duplex pipes differ from duplex stainless steel pipes? +

Super duplex grades carry higher molybdenum, nitrogen, and chromium content than standard duplex 2205, raising pitting resistance for service in aggressive marine and chloride-bearing environments.
