Copper; tubes and pipes, of copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver)

HS code 741122 covers the import and export of copper tubes and pipes made from copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver). These specialized copper alloy products are widely used in various industries, including plumbing, HVAC, and chemical processing, due to their corrosion resistance, durability, and thermal conductivity. As a key component in many industrial applications, the trade of 741122 products plays a vital role in the global economy.

The production of copper tubes and pipes under HS code 741122 typically involves a multi-step process. First, the copper-nickel or copper-nickel-zinc alloy is produced by melting and alloying the raw materials. The molten alloy is then cast into billets or ingots, which are subsequently hot-rolled or extruded to form the initial tube or pipe shape. Further processing, such as cold-drawing, annealing, and finishing, may be employed to achieve the desired dimensions, surface finish, and mechanical properties of the final product.

The main inputs required for the production of 741122 copper tubes and pipes include copper, nickel, and zinc as the primary raw materials. Specialized machinery, such as melting furnaces, rolling mills, and drawing equipment, are also essential for the manufacturing process. Additionally, energy sources, such as electricity or natural gas, are needed to power the production facilities.

The primary output of HS code 741122 is copper tubes and pipes made from copper-nickel base alloys (cupro-nickel) or copper-nickel-zinc base alloys (nickel silver). These products are widely used in various industries, including 741510 Copper; sanitary ware and parts thereof, 841430 Compressors used in refrigerating equipment, and 842139 Filtering or purifying machinery and apparatus for gases, among others. The versatility and corrosion resistance of 741122 copper alloy tubes and pipes make them valuable inputs for a range of industrial applications.
