Sandco Metal Industries specialize in manufacturing of Super Duplex Pipes & Tubes available in various grades and dimensions at affordable cost with no quality compromise. We are manufacturing Super Duplex Pipes & Tubes from past 25 years under supervision of technical experts with their expert guidance and support. Our Organization is ISO-9001:2008 certified with added advantage of products electro polishing, cutting as per customer requirements. 

Super-Duplex pipes & Tubes are known as high alloyed, high-performance Duplex steel with a pitting resistance equivalent of >40 (based on Cr% + 3.3Mo% + 6N%). The chemical composition due to high contents of chromium, nickel , molybdenum improve its inter granular and pitting corrosion resistance capabilities. Addition of nitrogen enhances structural hardening by interstitial solid solution mechanism thus raising the yield strength without impairing toughness. Due to its high level of chromium, they provide outstanding resistance to acids, acid chlorides, caustic solutions and other environments in the chemical/petrochemical, pulp and paper industries. Our Super Duplex Pipes & Tubes are available as seamless, welded and ERW (ERW stands for Electric Resistance Welded) pipes & tubes .

Super Duplex Seamless Pipes & Tubes

Super Duplex Seamless Pipes & Tubes Supplier, Super Duplex Seamless Pipes & Tubes Exporter, Super Duplex Seamless Pipes & Tubes Distriburter, ASTM A815 UNS S32750 Super Duplex SteelSeamless Pipes in India & Tubes, Ferritic / Austenitic Super Duplex 2507 Seamless Tubing, Super Duplex UNS S32950 Seamless Pipes & Tubes

 Seamless pipes are made by drawing a solid billet over a piercing rod to create the hollow shell. As they do not require any welding, seamless pipes are considered to be stronger and more reliable. The advantage of seamless steel pipes lies in their ability to withstand pressure.

Super Duplex Welded Pipes & Tubes
