What is a C71500 copper nickel tube?
The performance of copper-nickel 70/30 tubing is affected by factors such as its specifications, grade, dimensions, wall thickness, and diameter. Processing methods include welding, electric arc welding (ERW), and submerged arc welding (LSAW). Tubing shapes include round, square, rectangular, and hydraulic types. Length is also an important consideration, and can be single or double random lengths. Tubing ends include beveled, threaded, and flat ends.
This tubing possesses excellent mechanical and physical properties, such as high density, high melting point, low tensile strength, low yield strength, and high elongation. Applications of copper-nickel 70/30 tubing include power generation, petrochemicals, natural gas processing, specialty chemicals, pharmaceutical equipment, pharmaceuticals, seawater equipment, chemical equipment, condensers, heat exchangers, and the pulp and paper industry.
