Anti-corrosion steel pipes play important and different roles in people’s daily life. Anti-corrosion steel pipes generally refer to the use of special processes to carry out anti-corrosion treatment on ordinary steel pipes (such as seamless pipes, welded pipes), so that the steel pipes have certain anti-corrosion properties. Corrosion ability is generally used for waterproof, anti-rust, anti-acid and alkali, anti-oxidation and other characteristics. Generally speaking, PE anti-corrosion steel pipe refers to polyethylene anti-corrosion steel pipe, which is a tubular article processed by advanced science and technology. PE anti-corrosion steel pipes are widely used in oil, natural gas, city gas, city water supply, coal-water slurry pipelines, etc.
Corresponding anti-corrosion measures can also be carried out on the inner and outer walls of steel pipes according to different needs. The common ones are epoxy coal tar pitch anti-corrosion steel pipes, polyurethane coating anti-corrosion, cement mortar anti-corrosion on the inner wall of anti-corrosion steel pipes, etc. Anti-corrosion steel pipes are mainly used in special requirements or Engineering fields in harsh environments.
Anti-corrosion steel pipe refers to steel pipes that have been processed by anti-corrosion technology, which can effectively prevent or slow down the corrosion phenomenon caused by chemical or electrochemical reactions during transportation and use. According to the statistical data of our country, the direct economic loss of domestic steel pipe corrosion is more than 280 billion yuan every year, and the global annual loss due to steel pipe corrosion is as high as 500 billion U.S. dollars. Anti-corrosion steel pipes can effectively prevent or slow down corrosion, prolong the service life of steel pipes, and reduce the operating cost of steel pipes. The characteristics of anti-corrosion steel pipes are corrosion resistance, no leakage, high toughness, excellent flexibility, good resistance to scratches, and good resistance to rapid crack transmission. In one, the service life of anti-corrosion steel pipes is greater than or equal to Under the environment of 60 degrees Celsius, it can have a life span of more than 50 years.
In addition to improving the service life of steel pipes through anti-corrosion, it is also manifested in the following aspects:
1. Combining the mechanical strength of steel pipe and the corrosion resistance of plastic.
2. The outer wall coating is more than 2.5mm, which is scratch-resistant and bump-resistant.
3. The friction coefficient of the inner wall is small, 0.0081-0.091, which reduces energy consumption.
4. The inner wall is smooth and not easy to scale, and has the function of self-cleaning.
