Ideal for chemical processing, power generation, and marine applications, these tubes are designed to offer long-lasting performance with minimal maintenance.① STANDARD: ASTM B161/ ASTM B163/ASME SB161/ASME AB163② OD RANGE : 6-457MM③ THICKNESS RANGE: 1-35 MM
Seamless UNS N08020 Nickel Alloy Steel Pipe refers to a high-performance corrosion-resistant alloy pipe, commonly known as Alloy 20 or Carpenter 20, is a nickel-iron-chromium austenitic alloy designed primarily for superior corrosion resistance in harsh chemical environments, particularly sulfuric acid. It is not a traditional carbon or low-alloy steel but a high-performance nickel-based superalloy with iron as a significant component (typically 32-46%). The "nickel alloy steel" designation in your query likely refers to its classification as a nickel-chromium-iron alloy used in steel-like piping applications. This material is stabilized with niobium (columbium) to prevent sensitization and intergranular corrosion, making it ideal for general corrosive service.Alloy 20 seamless pipes are produced under the ASTM B729 specification (or its ASME SB729 boiler code equivalent), which covers seamless, cold-worked, or hot-finished pipes and tubes in UNS N08020, N08026, and N08024 grades. These pipes are furnished in a stabilized-annealed condition unless otherwise specified.
Hastelloy C2000 Seamless Nickel Alloy Steel Pipe, is a high-performance material used primarily in demanding corrosive environments.Corrosion Resistance: Highly versatile. It offers outstanding resistance to a wide range of oxidizing and reducing chemicals, including hot contaminated mineral acids (like sulfuric and hydrochloric acids) and process streams with ferric ions and dissolved oxygen.Localized Corrosion: Excellent resistance to pitting and crevice corrosion, especially in the presence of chlorides.Seamless pipe and tube made from Hastelloy C-2000 are primarily covered by the following ASTM/ASME specifications:ASTM B622 / ASME SB622: Standard Specification for Seamless Nickel and Nickel-Cobalt Alloy Pipe and Tube.
Hastelloy B3 Seamless Nickel Alloy Steel Pipe is a high-performance nickel-molybdenum alloy tube specifically designed to offer excellent resistance to hydrochloric acid and other strongly reducing chemicals. Known for their enhanced thermal stability and improved fabricability, these tubes are widely used in harsh chemical environments. ① STANDARD: ASTM B622/ ASTM B829 ...② OD RANGE : 6-457 MM③ THICKNESS RANGE: 1-45 MM
