Model:50-4200mm
Diameter range:50-4200mm
Extrusion Capability:≤350m²/h
Materials used: epoxy powder, adhesive, polyethylene
Main equipment: steel pipe external blasting equipment, steel pipe conveyor system, intermediate frequency heating equipment, epoxy powder coating equipment, AD adhesive extrusion equipment, PE polyethylene extrusion equipment, cooling equipment, PE beveling equipment, print label equipment, etc
According to customer demand for the production of different specifications products.
The lines can be applied to FBE, 2 layer FBE, 2 layer PE, 2 layer PP and 3 layer PE anti-corrosion coating.
3 layer PE anti-corrosion coating consists of first FBE coating, middle adhesive layer and outer polyethylene layer.
The steel pipe anti-corrosion coating line is employed for applying anti-corrosion coatings to steel pipes in the factory with different diameters, which is more extensively utilized in various types of engineering projects, particularly in heating, gas, and oil sectors.

The composition of 3-layer PE coating production line
The three -layer PE anticorrosion structure includes fusion bonded epoxy-powder bottom layer, polymer adhesive middle layer and polyethylene top layer. The so-called 3-layer PE Coating Production line,3-layer refers to the 3-layer structure of epoxy primer, that is a thermosetting, non-toxic coating, curing after form high molecular weight cross-linked structure coating, With excellent chemical corrosion resistance and high mechanical properties, especially the best wear resistance and adhesion. It can form a continuous coating and steel pipe surface directly bonded, with good resistance to chemical corrosion and anti-cathode stripping performance. 
To ensure that the overall coating at a higher temperature Has a good adhesion, making the middle layer of adhesive reactive groups to form a chemical bond. That is high quality of steel pipe anti-corrosion coating buried in the ground.


The intermediate layer is usually a copolymer binder, the main component of which is polyolefin, and is widely used as a vinyl copolymer adhesive. The polar moiety of the copolymer adhesive and the epoxy group of the epoxy primer can react to form hydrogen bonds or chemical bonds to form a good bond between the intermediate layer and the substrate; and the non-polar ethylene moiety has a Good affinity, so the middle layer and the surface layer also has a good bonding performance. Three-layer structure of polyethylene anti-corrosion, as the buried pipe outside the protective layer is very superior, and the technology has been widely used in the West-East Gas and oil field oil supply, urban gas supply, water pipeline used on the anti-corrosion.
