Products Description

Copper-nickel pipe manufacturers produce a variety of copper-nickel pipe compositions. The copper-nickel family encompasses various compositions and material grades, and GNEE's copper-nickel pipe manufacturers produce a wide variety of different types of pipe. Grades of copper-nickel include C70600, C71500, 90/10, and more. These differences in copper-nickel pipe are due to the varying ratios of copper and nickel in the material. Copper-nickel pipe offers excellent corrosion resistance and a long service life. These pipes are primarily used in seawater and marine applications.

ASTM B466 pipe sizes range from ¼ inch to 12 inches. Pressure capacities for these pipes range from 10 gauge to 160 gauge. Copper-nickel pipe suppliers also produce pipe in various lengths, up to 13 meters. Production processes include rolling, cold drawing, hot working, stress relieving, annealing, quenching, or tempering. Different copper-nickel pipe specifications, such as DIN 86019 pipe, are suitable for different applications. Copper-nickel pipe can also be manufactured with plain or beveled ends. Dimensions vary depending on the standard, with outer diameters ranging from 3 mm to 114.3 mm. Copper-nickel tubing can also be made seamless, hot-rolled, cold-drawn, welded, or electric-resistance-welded. Industries such as defense, shipbuilding, refineries, and power plants use copper-nickel tubing for its increased strength, corrosion resistance, and longer service life. Copper-nickel tubing suppliers also offer products for evaporators, heat exchangers, chillers, power plants, and other high-corrosion applications.
