ASTM B466 - Seamless Pipe and Tube

Astm B466 Copper Nickel pipe and tube

Curpo Nickel ASTM B466 Pipes are an alloy of copper and nickel, along with fortification elements such as manganese and iron. Copper Nickel Alloy Tubes show some higher corrosion resistance in seawater. The copper alloy(cupro nickel tubes) that is used for heat exchangers and condensers has certain specifications like, it contains 1 to 4.5 wt % of Zn, 1.0 to 2.5 wt %, preferably 1.5 to 2.0 wt % of Sn, 0.005 to 0.05 wt %, 0.01 to 0.04% of P, and the rest balance substantially copper and unavoidable impurities. This particular alloy tubes exhibit high levels of corrosion resistance like, stress corrosion cracking, dezincification corrosion and more. The other features are superior workability, strength and solder wettability, thus is ideal to be used in Heat Exchangers & Condensers. Such Cupro nickel tubes and pipes used in Heat Exchangers & Condensers play a vital role in all industrial fields. Thus, it is being used for piping systems, marine hardware, and at times for the crankshafts, propellers and hulls of finest fishing boats, tugboats, and other working boats.

Scope And Manufacturing

ASTM B466 specification establishes the requirements for seamless copper-nickel pipe and tube in straight lengths, suitable for general engineering purposes. Each product should be manufactured from cast billets by hot extrusion or piercing and then subjected to cold working and annealing. The standard tempers for the products in this specification are soft annealed (O60), light drawn (H55), hard drawn (H80), and hard drawn and end annealed (HE80). Pipe and tube tensile properties, Rockwell hardness, and test performance should conform to the values specified herein. Performance requirements include those from expansion, flattening, and eddy Current tests.

The product shall be manufactured by such hot extrusion or piercing and subsequent cold working and annealing as to produce a uniform, seamless wrought structure in the finished product.
