Product Description ASTM B466/B466M Seamless Copper-Nickel Pipe and Tube for Saltwater Piping/Heat Exchangers/CondensersThe standard covers pipes and tubes made from two specific copper-nickel (Cu-Ni) alloys:UNS C70600: Copper-Nickel alloy with a nominal composition of 90% Copper and 10% Nickel.UNS C71500: Copper-Nickel alloy with a nominal composition of 70% Copper and 30% Nickel.These alloys are specifically chosen for their excellent corrosion resistance, particularly in marine environments.2. Manufacturing Process:The product is mandated to be seamless, meaning it is formed without a welded seam. This is achieved by processes like extrusion or piercing a solid billet.The seamless construction provides superior mechanical strength, pressure integrity, and resistance to corrosion, which is critical for the intended applications.3. Scope and Application:This specification is designed for components used in critical systems, primarily:Saltwater Piping: For handling seawater in marine and offshore applications (e.g., shipboard piping, desalination plants).Heat Exchangers: Where tubes carry a fluid (often seawater) to transfer heat.Condensers: Specifically in power plants and marine applications where steam is condensed using cool water (often seawater) circulated through the tubes.4. Key Properties:Corrosion Resistance: Excellent resistance to corrosion and biofouling in seawater and brackish water.Erosion Resistance: High resistance to impingement attack and erosion from fast-flowing water.Fabricability: Good ductility and ability to be bent, flared, and brazed or welded.Thermal Conductivity: Good heat transfer properties, making it ideal for heat exchanger and condenser applications.5. Standard Designation (B466 vs. B466M):The dual designation B466 / B466M indicates that the standard supports both U.S. Customary units (B466) and Metric units (B466M).The values stated in either system are not exact equivalents and must be used independently of each other to avoid specification errors.6. Product Forms:The standard covers pipes and tubes in various tempers (drawn, annealed) and in a range of sizes, including:Pipe: Typically specified by Nominal Pipe Size (NPS) or diameter.Tube: Often specified by outside diameter and wall thickness.Company ProfileProduct Description Specification / RequirementDetails / ExamplesChemical CompositionStrict elemental control based on UNS alloy.- Major Elements: Nickel (Ni), Chromium (Cr), Cobalt (Co), Molybdenum (Mo), etc., must fall within specified ranges for the specific alloy (e.g., N06625, N10276).- Trace Elements: Carbon (C), Sulfur (S), Phosphorus (P), Silicon (Si) are tightly controlled to ensure performance.Mechanical PropertiesRequirements vary by specific UNS alloy and temper condition.- Tensile Strength: Minimum required (e.g., ≥ 120 ksi / 827 MPa for annealed UNS N06625).- Yield Strength: Minimum required.- Elongation: Minimum percentage required.Inspection & TestingMandatory and optional tests to ensure quality.- Chemical Analysis: Performed on a sample from each heat (melting batch).- Tension Tests: One test required per lot of pipe.- Hydrostatic Testing: Applied by agreement or if specified in the purchase order (optional unless specified).- NDE (Non-Destructive Examination): Methods like Radiography or Dye Penetrant inspection may be applied to the weld seam if required.- Visual Inspection: Surface must be free of defects exceeding acceptance criteria.
