Bereket Pipes is a reliable manufacturer and supplier of Stainless Steel 321/321H Heat Exchanger Tubing, located in Addis Ababa, Ethiopia, providing high-performance tubing solutions for thermal and high-pressure services. Designed with superior resistance to heat and intergranular corrosion, Bereket Pipes’ Stainless Steel 321/321H Heat Exchanger Tubing is best suited for applications in systems that are exposed to continuous high temperatures. Bereket Pipes supplies vital industries like power generation, chemical processing, oil and gas, and aerospace with tubing that meets global standards and provides long-term performance under adverse service conditions.
Stainless Steel 321/321H Heat Exchanger Tubing is comprised of 17–19% chromium and 9–12% nickel titanium-stabilized austenitic stainless steel. Grade 321 has titanium to avoid carbide precipitation after welding, whereas 321H includes more carbon content (up to 0.10%) for improved creep and high-temperature strength. The tubes provide a tensile strength of 515–750 MPa and a yield strength of about 205 MPa. Both grades retain corrosion resistance and structural stability at temperatures of up to 870–900°C, with 321H being the choice where increased mechanical strength is necessary at high temperatures.

Stainless Steel 321/321H Heat Exchanger Tubing is applied in superheaters, heat exchangers, boiler systems, refinery units, and exhaust gas treatment systems. It performs particularly well in thermal cycling applications as well as welded structures that are involved in continuous high-temperature service. The 321 stabilization of titanium does not cause sensitization, but the presence of more carbon in 321H enables higher performance in pressure-containing and high-heat services. These tubes offer a reliable and effective heat transfer solution for corrosive and high-temperature applications, guaranteeing reliability and longer service life.
