Bereket Pipes, a top-notch manufacturer and supplier based in Addis Ababa, Ethiopia, specializes in high-quality Stainless Steel 321 and 321H ERW Pipes. These pipes are specifically designed to handle high temperatures, resist corrosion, and meet the demands of various industrial applications. Crafted to comply with international standards, these Electric Resistance Welded (ERW) pipes boast impressive durability, tensile strength, and resistance to oxidation, intergranular corrosion, and stress corrosion cracking. Bereket Pipes is committed to delivering superior quality by utilizing advanced ERW manufacturing techniques, ensuring precise dimensional control, and conducting rigorous quality testing. This results in pipes that feature smooth finishes, consistent wall thickness, and dependable mechanical properties. They find extensive use in the petrochemical, chemical processing, power generation, and oil & gas sectors, especially for critical high-temperature applications.
The Stainless Steel 321 and 321H ERW Pipes are made from titanium-stabilized austenitic stainless steel, which includes chromium, nickel, and titanium. The 321H variant, with its higher carbon content, offers enhanced high-temperature strength and creep resistance. Both grades excel in resisting intergranular corrosion, pitting, and oxidation, even in harsh environments. On the mechanical side, these pipes deliver high tensile and yield strength, toughness, and fatigue resistance, all while maintaining good weldability and machinability. Their ERW construction guarantees uniform wall thickness, dimensional stability, and reliable performance under high-pressure and high-temperature conditions.
