1. Cleaning Uses solvents and emulsions to clean the surface of steel to remove oil, grease, dust, lubricants and similar organics. However, it cannot remove rust, oxide scales, and welding flux on the surface of steel. Therefore, it is only used as an antiseptic product. Aids.
2, tool rust Mainly use wire brush and other tools on the surface of the steel, can remove loose or tilt of the scale, rust, welding slag and so on. The manual tool derusting can reach Sa2 level, and the derusting of power tools can reach Sa3 level. If the steel plate surface is attached with a solid iron oxide scale, the rust removal effect of the tool is not satisfactory, and the depth of the anchoring lines required for anti-corrosion construction cannot be achieved.
3, pickling Generally use chemical and electrolytic methods to do pickling treatment, pipeline anti-corrosion chemical pickling only, you can remove oxide scale, rust, old coating, and sometimes can be used as a sand blasting after retreatment. Although chemical cleaning can make the surface reach a certain degree of cleanliness and roughness, its anchorage is light and it is easy to pollute the environment.
Whether it's hydroponics, plants in soil, you can add a touch of magic to every veg and flower with Xeccon grow lights.
With the continuous development of China's economy, the country vigorously develops the energy industry, and long-distance oil and gas pipelines are an important means of energy security. During the construction of anti-corrosion pipelines for oil (gas) pipelines, surface treatment of steel pipes is a key factor in determining the service life of pipelines. First, it is the premise that the anticorrosion layer and the steel pipe can be firmly combined. After verification by the research institute, the life of the anti-corrosion coating depends on the coating type, coating quality and construction environment. The effect of surface treatment of the steel pipe on the life of the anti-corrosion coating accounts for approximately 50%. Therefore, the anticorrosion layer should be strictly adhered to. The requirements of the surface of the steel pipe are continuously explored and summarized to continuously improve the steel pipe surface treatment method.
