Silver Tubes is a reputed super duplex steel supplier and trading house of Super Duplex Stainless Steel S32750 Pipes and Tubes, known for their exceptional strength and corrosion resistance. Our Super Duplex Stainless Steel Seamless S32750 Pipes are engineered to resist pitting, crevice corrosion, erosion corrosion, stress corrosion cracking, and corrosion fatigue, making them ideal for demanding industrial environments. The high chromium and molybdenum content in SA 790 UNS S32750 pipes ensures outstanding resistance to uniform corrosion caused by organic acids such as formic and acetic acid.
We supply Super Duplex Stainless Steel Seamless S32750 Tubes and UNS S32750 Welded Pipes to critical sectors like the oil & gas industry, offshore platforms, heat exchangers, and process & service water systems. These Super Duplex UNS S32750 Welded Pipes are also used in fire-fighting systems, injection and ballast water systems, chemical process industries, heat exchangers, vessels, and piping. Our Super Duplex UNS S32750 EFW Pipes also provide excellent resistance to inorganic acids, especially those containing chlorides.
Our Super Duplex UNS S32750 EFW Pipes offer excellent resistance to inorganic acids, especially those containing chlorides. Built from an approximately 50/50 mix of austenitic and ferritic phases, UNS S32750 ERW Pipes are often referred to as austenitic-ferritic stainless steels. These Super Duplex Steel S32750 Pipes combine the best of both worlds—high strength and ductility from ferritic steels with the superior corrosion resistance of austenitic steels.
Stainless Steel S32750 Pipes combines the best attributes of both austenitic and ferritic stainless steels and provides high strength/ductility with good corrosion resistance to corrosion (including stress corrosion cracking).
Super Duplex S32750 Pipes are generally more complex and offer even higher strength and corrosion resistance making them suitable for very demanding applications such as offshore marine engineering.
We also offer Super Duplex 2507 Pipes, a premium variant designed for even more aggressive environments. These pipes and tubes are suitable for extremely corrosive and high-pressure applications in marine engineering, offshore rigs, and chemical industries.
Additionally, we manufacture and supply Super Duplex Steel S32760 Pipes and Super Duplex Steel Tubes tailored to meet global standards. Our quality controllers perform rigorous inspections to ensure defect-free delivery and top-notch performance.
