Iris Pipes and Tubes, located in Cairo, Egypt, stands out as a leading manufacturer and supplier of top-notch industrial piping solutions, including Super Duplex Steel Boiler Tubing. This tubing is engineered to deliver outstanding strength, resist corrosion, and withstand high temperatures, making it a reliable choice for demanding boiler and heat exchange systems. At Iris Pipes and Tubes, advanced manufacturing techniques and strict quality control measures are employed to meet international standards. The Super Duplex Steel Boiler Tubing is particularly resistant to pitting, crevice, and stress corrosion, which makes it perfect for industries like power generation, petrochemical, chemical processing, and marine, where safety, efficiency, and long-lasting performance are essential.
This specialized tubing is made from high-alloy stainless steel, featuring around 25-26% chromium, 6-7% nickel, 3-4% molybdenum, and nitrogen, which together provide exceptional corrosion resistance and mechanical strength. It boasts high tensile and yield strength, remarkable toughness, and resistance to fatigue. The tubing maintains its structural integrity even under high pressure and elevated temperatures, while also resisting pitting, crevice, and stress corrosion cracking. Thanks to precision manufacturing, it ensures uniform wall thickness, a smooth surface finish, and leak-proof performance. These characteristics make Super Duplex Steel Boiler Tubing an excellent choice for critical industrial applications that demand long-term reliability and durability in harsh environments.
