Standard Specification for Nickel-Copper Alloy (UNS N04400) Seamless Pipe and Tube
|Publication Date:||19 February 1971|
|ICS Code (Nickel and chromium products):||77.150.40|
This specification covers nickel-copper alloy (UNS N04400)• in cold-drawn (see Section 2) seamless pipe and tube intended for general corrosive service and for mechani.:al applications. in sizes 8% in. (219 mm) and under in outside diameter. and with wall thicknesses of 0.500 in. (12.7 mm) and under. Pipe is available in various schedules (Appendix A2). Tube may be specified to two dimensions only (length excepted) as follows:
Outside diameter and average wall (preferred) (Note 1).
Outside diameter and inside diameter (Note 2), 1. 1.3 Inside diameter and average wall (Note 2).
NOTE 1 - Tube produced to outside diameter and minimum wall. may be furnished upon agreement between the manufacturer and the purchaser.
NOTE 2 - Tube is available commercially in a wide range of outside diameters and wall thicknesses. When produced to outside diameter and inside diameter and to inside diameter and arerage wall. the range of sizes is more limited and the manufacturer should be consulted as to whether dies and tools arc available or whether the sizes desired will necessitate production of special dies and tools.
Hot-finished (extruded) tube is available in some of the sizes provided for in this specification and also in larger diameter and heavier wall thicknesses than indicated in 1.1. The surface condition, properties and permissible tolerances in this specification are not applicable to such material. and the manufacturer should be consulted
For tube intended for condenser and heat-exchanger service, reference :should be made to ASTM Specification B 163. for Seamless Nickel and Nickel Allov Condenser and Heat-Exchanger Tubes."
Material is available in the following conditions (tempers) and finishes (Appendix Al):
See also Appendix A3 for other tem· pers available in small diameter. light wall tubing (converter sizes).
It should be understood that this specification is general. Provision is made herein for material suitable for hot- and cold-working operations, machining, welding. and other common methods of fabrication. Since the material may be used for purposes where the requirements of the operations are too particular to be prescribed in general specifications, it is advisable in these instances for the purchaser to submit samples or detailed information to the manufacturer and secure an adjustment of processing to suit the conditions for which the material is intended (Section 16).
NOTE 3 - The values stated in U.S. customary units arc to be regarded as the standard. The metric equivalents of U.S. customary units may be approximate
