Example Embodiment
[0041]Example 1
[0042]This embodiment provides an anti-corrosion stainless steel pipe for ships, which includes an anti-corrosion stainless steel pipe and an anti-corrosion paint applied to the surface of the anti-corrosion stainless steel pipe. The anti-corrosion stainless steel pipe includes the following elements in terms of mass percentage:
[0043]Chromium Cr: 14%;
[0044]Nickel Ni: 10%;
[0045]Titanium Ti: 0.1%;
[0046]Niobium Nb: 0.1%;
[0047]Molybdenum: 1.5%;
[0048]Silicon Si: 0.8%;
[0049]Carbon C: 0.03%;
[0050]Sulfur: 0.015%;
[0051]Nitrogen N: 0.01%.
[0052]The balance is Fe and other unavoidable impurities, and the sum of the mass percentages of the above elements is 100%.
[0053]In this embodiment, the anti-corrosion coating adopts one of alcohol-soluble phenolic resin, modified phenolic resin, pure phenolic resin or polyurea elastic coating.
[0054]A method for preparing the above-mentioned anti-corrosion marine stainless steel pipe includes the following steps:
[0055]S1, ingredients;
[0056]S2,...
