Manufacturing Process of Cupronickel Tubes

The manufacturing process for cupronickel tubes typically involves several stages, including melting, ingot casting, hot rolling, cold rolling or cold drawing, heat treatment, and finishing. To ensure dimensional precision and high surface quality, modern production lines often utilize advanced automated control equipment, enabling the precision processing of tubes with outer diameters ranging from 1 mm to 100 mm-or even broader ranges. While these tubes are predominantly circular, custom-shaped profiles can also be produced to meet specific requirements. Products are generally weighed to ensure fair and accurate transactions. Regarding hardness, tubes can be supplied in various tempers-such as annealed (soft) or cold-rolled (hard)-to suit specific installation and application needs.
