Bereket Pipes is a leading manufacturer and distributor of super duplex steel seamless tube, based in Addis Ababa, Ethiopia. It specializes in providing high-performance tubing solutions designed for severe service applications in sectors including offshore oil and gas, petrochemicals, marine, and power generation. Bereket Pipes makes sure that every seamless tube is according to international standards of strength, corrosion resistance, and dimensional accuracy. With superior production capacity and a robust quality control process, the company offers super duplex seamless tubing that demonstrates consistent performance in high-pressure, high-corrosion, and high-temperature applications.
Super duplex steel seamless tubing is usually produced from grades like UNS S32750 and S32760. These alloys exhibit a double-phase microstructure of austenite and ferrite, providing outstanding strength and corrosion resistance. The chemical structure consists of high concentrations of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen, which bring added resistance to pitting, crevice corrosion, and stress corrosion cracking. Mechanically, the tubing offers extremely high yield and tensile strength, high fatigue strength, and good toughness even under cryogenic conditions. The seamless design removes welds and maximizes the structural integrity and resistance to failure in demanding applications.
