Industrial Seamless Nickel Pipes

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.
