What are the anticorrosion methods of anticorrosive welded steel pipe

  Anticorrosive welded steel pipe is a kind of interpenetrating network polymer, which can initiate polymerization at room temperature. The two networks can learn from each other and produce a cooperative effect. It is a new type of anticorrosive coating with strong adhesion, high strength, abrasion resistance, hydrolysis resistance, corrosion resistance, water resistance and weather resistance. The requirements for rust removal on steel structure surface are not high, and the service temperature can be between - 20 and 120 Within ℃

  What are the anticorrosion methods of anticorrosive welded steel pipe

必威彩票平台  1. Protective layer method of anticorrosive welded steel pipe

必威彩票平台  The protective layer method of anti-corrosion welded steel pipe is widely used. This kind of anti-corrosion method is to make protective layers of various materials on the surface of metal to isolate the metal products from the external corrosive medium, so as to achieve the effect of preventing corrosion. The protective layer of anticorrosive steel pipe can be formed by coating, spraying, electroplating, hot plating, spray plating, etc.

  There are many kinds of protective coating materials for anticorrosive welded steel pipe, such as oil, paint and other coatings, and non-metallic materials such as ceramics and plastics. The electroplating and hot-dip plating of anticorrosive steel pipes generally use non corrosive metals, such as zinc, tin, chromium and nickel. Another material of anticorrosive welded steel pipe is the oxide film formed on the surface of steel, that is, black ferric oxide film, which can also play an anti-corrosion role.

  2. Structural change method of anticorrosive welded steel pipe

必威彩票平台  One of the common methods of anticorrosive welded steel pipe is to change the structure of metal. There are many kinds of metals. Some heavy metals have low chemical activity and are not easy to be corroded by other substances. Some metals can effectively improve the anti-corrosion ability when used with other metals. For example, adding chromium, nickel and other materials to ordinary steel to make stainless steel can obtain better anti-corrosion effect.
