Straight Seam Resistance Welded Steel Pipe 3pe Anticorrosion Case

ERW in straight seam high-frequency electric resistance welded pipe means resistance welding, which has the characteristics of high production efficiency, low cost, material saving and easy automation. Therefore, it is widely used in various industrial sectors such as aviation, aerospace, energy, electronics, automobile, light industry, etc. It is one of the important welding processes. ERW straight seam high-frequency electric resistance welded pipe is a “high- frequency electric resistance welded steel pipe”. It is different from the ordinary welded pipe welding process.

The weld bead is melted from the base metal of the steel strip body, and the mechanical strength is better than that of the general welded pipe.Straight seam welded pipe 3pe anti-corrosion has been recognized by everyone, and its application is also very wide, but 3pe anti-corrosion steel pipe has been continuously researching and developing new technology in order to better meet people’s needs. 3PE anti-corrosion steel pipe manufacturers have succeeded in the latest technology nanotechnology in recent years.

The technology is combined with 3PE anti-corrosion steel pipes. At present, all countries in the world attach great importance to the research on corrosion control issues, and have achieved many achievements in the field of pipeline anti-corrosion coatings, and various new materials and new technologies are emerging. The life of the three- layer PE is expected to be more than 40 years, but the price is relatively expensive. Currently, it is widely used in Europe, while the US application is less.

Since the introduction of China in 1995, the main steel pipe factory has established a three-layer PE anti-corrosion production line. The Shaanxi-Beijing gas pipeline and the Kuqian pipeline have a total of about 2,000 km of three-layer PE, and the West-East Gas Pipeline Project also uses the anti-corrosion layer.

Since the properties of the surface materials involved in corrosion protection are determined by the microstructure, the emergence and application of nanotechnology will undoubtedly bring huge opportunities for the development of corrosion control technology. Studies have shown that the use of nanotechnology to modify the organic coating anti-corrosion materials can effectively improve its overall performance, especially increase the mechanical strength, hardness, adhesion, light resistance, aging resistance, weather resistance and so on.

Since the 1950s singular long-distance pipeline has cited the petroleum asphalt anti-corrosion technology of the former Soviet Union, petroleum asphalt has been the most commonly used anti-corrosion layer in China for a long period of time.

In the 1970s and 1980s, a variety of anti-corrosion materials such as tapes, jackets, and epoxy powders were put into use one after another, and the situation in which petroleum asphalt dominated the world began to change. In 1995, the anti-corrosion layer of coal tar enamel began to be applied in the pipelines such as the double-track and the Jingxi. In the late 1990s, the two kinds of anti-corrosion layers of FBE and three-layer polyethylene (three-layer PE) gradually became In the mainstream, double-layer epoxy (double-layer FBE) has gradually begun to scale applications in recent years.
