FBE, 2PP, 3LPE/3PE Coating Steel Pipe

Allland produce and export large quantity FBE, 2PP, 3LPE/3PE coating steel pipes/anti-corrosion pipes.
External & internal coatings. Anti-corrosion coatings act as a barrier layer that prohibits or slows down the formation of corrosion on the underlying metal surface of the carbon steel pipe. By preventing external corrosion with the use of either single or multi-layer anti-corrosion coatings, it ensures precious natural resources and other products reach their destination safely and efficiently.

1、 Production process
The production process of coated steel pipes mainly includes raw material preparation, steel pipe pretreatment, coating treatment, curing and cooling, as well as inspection and packaging. Among them, coating treatment is the core process, and common coating treatment methods include hot-dip molding, spraying, electrostatic spraying, etc.
Hot dip molding process: After preheating the steel pipe to a certain temperature, plastic powder is coated on the steel pipe through a spray gun or electrostatic adsorption, and then sent to a constant temperature electric furnace for heat treatment, so that the plastic powder melts and adheres to the surface of the steel pipe.
Spray coating process: Use a spray gun to spray pre prepared plastic coating onto the surface of the steel pipe, forming a uniform and dense coating.
Electrostatic spraying process: Electrostatic powder coating is sprayed onto the surface of pre treated steel pipes, and the powder is attached to the surface of the steel pipes through electrostatic adsorption effect, and then sent to a constant temperature oven for curing.
2、 Performance characteristics
Coated steel pipes have various excellent performance characteristics, mainly including:
Excellent corrosion resistance: The coating material of coated steel pipes has excellent corrosion resistance, which can effectively prevent rusting and corrosion of steel pipes and extend their service life.
Good wear resistance: The coating material of the coated steel pipe has good wear resistance, which can reduce the wear of the steel pipe during use.
Good high temperature resistance: The coating material of partially coated steel pipes can maintain stable performance in high temperature environments and is suitable for high temperature applications.
Good insulation: The coating material of coated steel pipes has good insulation properties, which can effectively prevent current leakage.
Good anti scaling properties: The coating material of coated steel pipes can effectively prevent scaling inside the pipeline and keep the pipeline unobstructed.
Good antibacterial properties: The coating material of partially coated steel pipes also has good antibacterial properties, which can effectively prevent bacterial growth.
