ASTM B111 / ASME SB111 Chemical Composition Tubes, SPECIFICATION

Standard Specification for Copper and Copper-Alloy Seamless Condenser Tubes and Ferrule Stock

This specification establishes the requirements for seamless tube and ferrule stock of copper and various copper alloys of a specified range of diameters, for use in surface condensers, evaporators, and heat exchangers. The specified coppers and copper alloys are UNS No. C10100, C10200, C10300, C10800, C12000, C12200, C14200, C19200, C23000, C28000, C44300, C44400, C4400, C60800, C61300, C61400, C68700, C70400, C70600, C70620, C71000, C71500, C71520, C71640, and C72200. The product shall be produced by processes such as casting, extrusion, drawing, annealing, straightening, trimming, and other processes which may produce a seamless tube in the specified condition. The coppers and copper alloys shall be specifically furnished in any one of the following tempers: annealed, light-drawn, hard-drawn, or hard drawn and end annealed. Tubes for ferrule stock shall be annealed sufficiently to be fully crystallized. Some tubes are suggested to be subjected to a stress-relieving thermal treatment subsequent to straightening. The products shall be subjected to expansion, flattening, and residual stress tests. The tensile and expansion requirements for the products are specified in accordance with the temper designation. The products shall also be subjected to mercurous nitrate, ammonia vapor, Eddy-current, hydrostatic, and pneumatic tests.

This specification2 establishes the requirements for seamless tube and ferrule stock of copper and various copper alloys up to 31/8 in. [80 mm] inclusive, in diameter, for use in surface condensers, evaporators, and heat exchangers. The following coppers and copper alloys are specified:3

ASTM B466 / ASME SB466 Chemical Composition Pipes and Tubes

Standard Specification for Seamless Copper-Nickel Pipe and Tube

This specification covers the requirements for seamless UNS C70400, C70600, C71000, C71500, C71520, and C72200 copper-nickel Pipes and Tubes in straight lengths suitable for engineering Applications. UNS C70620 and C71520 copper alloys are intended for products that are to be welded subsequently. 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.

1.1 This specification establishes the requirements for seamless copper-nickel pipe and tube in straight lengths, suitable for general engineering purposes. The alloys involved are copper alloys UNS Nos. C70400, C70600, C70620, C71000, C71500, C71520, and C72200.

1.1.1 Copper alloys UNS Nos. C70620 and C71520 are intended for product that will be subsequently welded.

1.2 Units—Values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
