Manufacturing Process of Cupro Nickel 90/10 Pipes & Tubes
Cupro Nickel 90/10 pipes and tubes are produced under a state of controlled processes to achieve an outstanding resistance against seawater corrosion, erosion and long-term durability. It is a good thermal conductor and has mechanical strength, hence it is applicable in the marine and industrial fields.
- Raw Material Selection
The primary elements are high-purity copper and nickel, and the additions of iron and manganese are controlled in order to improve corrosion resistance and the overall mechanical performance. - Melting and Alloying
Melting the raw materials through induction or electric furnace is done to give the raw materials a homogenous chemical composition. The process reduces the impurities and guarantees the uniformity of material properties. - Hot Working and Forming
Hot working methods including extrusion or rolling are used to create the alloy in the form of pipes and tubes. The processes are used to keep the correct dimensions and evenness of the wall thickness. - Heat Treatment
The annealing of the solution is done to alleviate the internal stresses and enhance ductility and corrosion resistance by moderating cooling. - Final Process and Control Quality
The last steps involve straightening, cutting, and surface finishing as well as quality checks like dimensional inspection and non-destructive tests to ensure that they meet the standards of the international standards.
Applications & Usage of Cupro Nickel 90/10 Pipes & Tubes
Cupro Nickel 90/10 pipes and tubes find application in areas where resistance to corrosion, thermal stability, and reliable operation in harsh environments are required.
