Steel tube outer wall corrosion protection form 3PE anticorrosion generally consists of three layers: First layer epoxy powder (FBE>100um),Second layer adhesive (AD) 170 ~ 250um. The third layer of polyethylene (PE) is 1.8-3.7mm In practice, three kinds of materials are mixed and integrated to form an excellent anticorrosive layer. Its processing mode is generally divided into two types: winding type and circular die cladding type.
3PE anticorrosive steel pipe coating is a new kind of anticorrosive steel pipe coating, which is a combination of 2PE anticorrosive coating in Europe and epoxy powder anticorrosive steel pipe coating (FBE) widely used in North America. It has been recognized and used all over the world for more than ten years.
The coating of 3PE anticorrosive steel pipe is epoxy powder anticorrosive coating on the bottom layer and the surface of the steel pipe, and the intermediate layer is copolymer adhesive with branch structure and functional group. The surface layer is a high density polyethylene anticorrosive coating.
Three PE anticorrosive coating combines the characteristics of high impermeability and high mechanical properties of epoxy resin and polyethylene. Up to now, it is the best anticorrosive coating with the best effect and performance, which has been used in many projects.
For the use of 3PE anticorrosive steel pipe many people only know one do not know the other, its role is really a very wide coverage, it is suitable for underground coal mine drainage, shotcrete, positive and negative pressure ventilation, drainage gas, fire sprinkler pipe network. Thermal power plant process water waste residue, return water pipeline. It has excellent applicability for water supply pipeline of anti-spray and sprinkler system. Power, communication, highway and other cable protection sleeve. Suitable for high-rise building water supply, heat supply network, tap water engineering, gas transmission, buried water and other pipelines. Petroleum transportation pipeline, chemical industry, pharmacy, printing and dyeing and other industries conveying corrosive medium process pipeline. Sewage treatment discharge pipe, sewage pipe and biological pool anti-corrosion engineering. It can be said that 3PE anticorrosive steel pipe is indispensable in the current construction, and it is believed that with the extension of science and technology, it will have more brilliant achievements in the future.
Ordinary steel pipe in the use of harsh conditions, can appear serious corrosion, which will reduce the service life of steel pipe, anti-corrosion insulation pipe service life is longer, generally is 30 to 50 years or so, you can use and correct installation and use is also can make the network maintenance costs low, anti-corrosion insulation pipe also can set the alarm system, automatic detection of pipeline leakage fault, the knowledge of the accurate fault location and alarm automatically.
3 PE anticorrosion insulation pipe heat preservation performance is good, heat loss is only twenty-five percent of the traditional pipe, long running or can save more resources, significantly lower energy costs, and has the stronger ability of water resistant and corrosion resistant, and also do not need to attached pipe trench, can be directly buried underground or in the water, on the construction is simple rapid, comprehensive cost is low, under the condition of low temperature and has good corrosion resistance and impact resistance, and in a certain environment can directly buried permafrost.
