Work with German AWM to develop highly sensitive hot bimetallic
Release time:2014-11-21
The bimetallic sheet is bonded together by a special process by two different expansion coefficients. Bimetallic sheet for the steam system, long-term immersion in high temperature condensate, bimetallic surface will continue to corrosion, resulting in metal fatigue, metal curvature weakened, resulting in leakage, reduce the life of bimetallic. Because the two kinds of metal can not be filled with the same amount of rust-proof elements, the domestic production of bimetal most of the metal is used with iron nickel chromium composition, the other side of the use of iron and manganese components, so iron and manganese corrosion resistance Relatively poor, relatively poor service life. As the bimetallic most of the electronic use of anti-corrosion properties do not need. While we use bimetallic use in the steam system to exclude condensate from water use without corrosion resistance. So I plant through long-term multi-party contact, made with the German AWM company, AWM company according to our factory made of metal double-sided must contain nickel chromium composition, and the content should be more than 18% requirements. And finally developed a corresponding anti-corrosion antioxidant highly sensitive hot bimetallic. After I plant a recent experiment and in the thermal power plant high temperature and high pressure steam system to achieve the desired effect. In the low-pressure steam system drainage temperature range of 80 degrees to 150 degrees.
