Problems solved by technology

[0002] At present, with the development and requirements of various industries, the required heat exchange copper tube material has high corrosion resistance and high erosion resistance, and the existing ones are mostly brass tubes or nickel white copper tubes. The disadvantages are as follows: the cost of brass tubes is low, but the corrosion resistance and processing performance are not as good as those of white copper tubes, and their service life is short, which requires regular maintenance and replacement, which has a great impact on the shutdown and maintenance of the overall equipment and machinery
Nickel white copper tubes are still not enough in the way of high corrosion resistance and high erosion resistance

Abstract

The invention discloses a zinc aluminum cupronickel pipe. The zinc aluminum cupronickel pipe comprises the following raw material components in parts: 30-35 parts of zinc, 25-30 parts of aluminum, 20-25 parts of iron, 5-10 parts of titanium, 250-300 parts of copper, 1-2 parts of scandium rare earth, 1-2 parts of dysprosium rare earth, 1-2 parts of neodymium rare earth, 1-2 parts of gadolinium rare earth, 1-2 parts of holmium rare earth, 1-2 parts of erbium rare earth, and 1-2 parts of thulium rare earth. The zinc aluminum cupronickel pipe has high corrosion resistance and high washout resistance, and can improve the surface quality of a copper pipe, refine alloy grains and improve the cooling performance.

Description

technical field [0001] The invention relates to the technical field of copper pipes, in particular to a zinc-aluminum white copper pipe. Background technique [0002] At present, with the development and requirements of various industries, the required heat exchange copper tube material has high corrosion resistance and high erosion resistance, and the existing ones are mostly brass tubes or nickel white copper tubes. The disadvantages are as follows: the cost of brass tubes is low, but the corrosion resistance and processing performance are not as good as those of white copper tubes. Its service life is short and requires regular maintenance and replacement, which has a great impact on the shutdown and maintenance of the overall equipment and machinery. Nickel cupronickel tubes are not enough in the way of high corrosion resistance and high erosion resistance. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned short...
