High-Efficiency Automatic 3PE Fbe Steel Pipe Anti-Corrosion Coating Production Line

Our 3LPE/3PE/FBE Steel Pipe Anti-Corrosion Coating Production Line is designed for high-performance corrosion protection of steel pipelines used in oil & gas transportation, municipal infrastructure, water supply, and industrial projects.

The complete line integrates steel pipe surface treatment, shot blasting, epoxy powder coating, adhesive and polyethylene extrusion, cooling, cutting, conveying and other processes. With advanced automation and precise process control, it provides uniform coating thickness, strong adhesion and reliable long-term corrosion resistance.

Suitable for a wide range of pipe diameters, the line can be customized according to the customer's pipe specifications, production capacity and coating requirements. Huashida provides complete technical solutions, equipment manufacturing, installation, commissioning and after-sales support.
 

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.
