Automatic 3LPE Coating Pipe Production Line with Induction Heating and SA2.5 Surface Treatment for Oil Gas Pipeline

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, especially in heating, gas, and oil sectors.
The lines can be applied to FBE, 2 layer FBE, 2 layer PE, 2 layer PP and 3 layer PE anti-corrosion coating.
The 3 - layer PE anti - corrosion coating contains a first FBE coating, an intermediate adhesive layer, and an outer polyethylene layer.

      Shot blasting equipment                                                   Dust removal equipment                                                   Epoxy powder equipment

Features:
1. Reduce costs
High sealing performance can greatly save energy, reduce costs, and protect the environment when the equipment operates for a long time.
2. Long service life
The operation is convenient and simple, the equipment production speed is fast, and the service life can reach 30-50 years.
3. Good impact resistance
It also has good impact resistance under low temperature conditions
4. Good anti-corrosion effect
Epoxy has high strength, low water absorption of PE, good softness of hot melt adhesive, and high anti-corrosion reliability.   The characteristics of this anti-corrosion method are simple production process, good anti-corrosion effect, and low price, which are widely recognized in the pipeline manufacturing industry as anti-corrosion methods.
5. Full automatic processing: PLC intelligent control system
The entire production line is equipped with a large number of sensors, which can statistically analyze position, speed, efficiency, and energy consumption, achieve automatic processing and high-precision stable processing, and ensure the accuracy of products and designs.


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.
