Product Process

1. Raw Material Selection: High-purity nickel is selected as the raw material for tube production. The nickel is typically sourced in the form of pellets, powders, or ingots to ensure consistent quality and purity.

2. Melting and Casting: The selected nickel material undergoes melting in a controlled environment to prevent contamination. Once molten, it is cast into billets or bars using molds of desired dimensions.

3. Hot Extrusion: The cast nickel billets or bars are then heated to high temperatures and forced through a shaped die to produce tubes of the desired diameter and wall thickness. This hot extrusion process ensures uniformity and precision in tube dimensions.

4. Cold Drawing: Following hot extrusion, the nickel tubes undergo cold drawing to further refine their dimensions and improve their mechanical properties. This process involves pulling the tubes through a series of dies at room temperature, resulting in a smoother surface finish and tighter tolerances.

5. Annealing: The cold-drawn nickel tubes are annealed in a controlled atmosphere to relieve internal stresses and enhance their ductility. Annealing also improves the tubes' resistance to corrosion and high temperatures.

6. Straightening and Cutting: The annealed nickel tubes are straightened to remove any deformations and cut to the required lengths using precision cutting equipment.

7. Surface Treatment: Depending on the application requirements, the surface of the nickel tubes may undergo various treatments such as polishing, cleaning, or coating to improve their corrosion resistance or appearance.

8. Quality Control: Throughout the production process, rigorous quality control measures are implemented to ensure that the nickel tubes meet specified standards for purity, dimensional accuracy, mechanical properties, and surface finish.

Application

1. Heat Exchangers: Pure nickel tubes are commonly used in heat exchangers for applications involving corrosive environments or high temperatures, such as chemical processing, petroleum refining, and power generation.
