3pe anticorrosive steel pipe process knowledge
In recent years, China has gradually completed the research and development and burial of anti-corrosion steel pipes, with the increase in the length of pipeline put into use, 3pe anti-corrosion layer reflects the separation of the negative electrode, the negative electrode separation is caused by the existence of the shortcomings of the anti-corrosion layer and the influence of external factors
It has become the development plan of the anti-corrosion layer outside the pipeline, the 3pe anti-corrosion steel pipe makes the pipeline applied in different work sites, in order to reduce or prevent the metabolic work of the pipeline, then what are the elements of the 3pe anti-corrosion steel pipe in Hebei Province
What is 3pe anti-corrosion steel pipe ?
Anti-corrosion steel pipes play a key role in our daily work. Anti-corrosion steel pipe usually refers to the unique process of anti-corrosion solution for general anti-corrosion steel pipe, so that the anti-corrosion steel pipe has a corresponding anti-corrosion level.
Usually used for moisture-proof, anti-corrosion, acid, vulcanization and other properties, 3pe anti-corrosion steel pipe usually refers to high pressure polyethylene anti-corrosion, 3pe anti-corrosion steel pipe is widely used in crude oil, gas, urban water supply, coal water slurry transportation pipelines and other fields.
Importance of Anticorrosion in Steel Pipes
General anticorrosive steel pipe in the harsh environment will produce obvious corrosion, which will reduce the service life of anticorrosive steel pipe, but Hebei 3pe anticorrosive steel pipe is not easy to rust
The service life of anti-corrosion insulation steel pipe is also correspondingly longer, usually can be applied for 30 years or 50 years, proper assembly and application can also reduce the cost of pipe network maintenance, anti-corrosion insulation steel pipe can also set an alarm system, automatically identify pipe network leakage errors, accurate familiar with the error mark and active warning.
Not only can reduce a lot of resources, but also reduce energy costs, it has a strong level of moisture and corrosion protection, and does not need to be attached to the pipe trench, can be immediately buried underground or underwater. In addition, it can also be immediately buried in frozen soil under the corresponding environment.
Spraying process of 3pe anti-corrosion steel pipe
It refers to the three coatings are powder electrostatic electrothermal spraying, the method does not need rolling, solves the problem of thin weld coating of spiral welded steel pipe, saves the equipment such as plastic extruder on the production line, and reduces energy consumption.
The steel pipe after shot peening is heated to 210° ~ 220°C at medium temperature, and the bottom epoxy powder is sprayed on the outer surface of the steel pipe. The epoxy powder is still in a molten state, and the adhesive and polyethylene are extruded into thin sheets by an extruder and wrapped around the steel pipe
It is then rolled flat, the method mainly depends on the shape of the coating itself: the epoxy powder is in powder form, the adhesive and PE are in granular form, and can only be wound by electrostatic spraying and plasticizing extrusion.
