Alloy 20 Pipes (UNS N08020) are high-performance, corrosion-resistant alloy pipes specifically designed for use in highly acidic and chemically aggressive environments. Composed primarily of nickel, iron, and chromium, with additions of copper and molybdenum, Alloy 20 offers excellent resistance to sulfuric acid, chloride-induced corrosion, pitting, and stress corrosion cracking.
These pipes are ideal for demanding applications in the chemical processing, pharmaceutical, food and beverage, and petrochemical industries. Their unique composition makes them particularly effective in handling sulfuric acid, phosphoric acid, and other harsh chemical solutions where standard stainless steel grades would fail.
We supply seamless and welded Alloy 20 pipes in accordance with international standards such as ASTM B729, B464, and B468, ensuring high strength, dimensional accuracy, and long-term performance. Pipes are available in a variety of schedules and sizes with end connections including Plain End (PE), Beveled End (BE), and Threaded End (TE).
At Middle East Piping, our Alloy 20 material is sourced from trusted manufacturers such as Carpenter Technology, Sandvik, and PCC Energy Group, ensuring full traceability and material certification. We supply across major industrial markets including Saudi Arabia, UAE, Qatar, Bahrain, and Kuwait, supporting EPC contractors, maintenance teams, and process industries with reliable delivery and documentation. click here
