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.

The three-layer polyethylene anti-corrosion coating, a leading technology, functions as the outermost protective layer for underground pipelines. It is extensively used in the corrosion prevention of gas and oil transmission lines, municipal gas supply systems, water pipes, and other fluid transport conduits, enhancing pipeline mechanical capabilities with superior electrical insulation, waterproofing, durability, and anti-aging features.
Corrosion-resistant steel pipes are primarily categorized into two main types: internally treated and externally treated.
Internally treated steel pipes are widely used, relatively low-cost, and utilize a coating to protect the pipe's interior. Externally treated steel pipes are primarily 3PE-coated, a mainstream technology. Qingdao Huashida's 3PE anti-corrosion production line utilizes mature technology, providing highly effective corrosion protection for both the exterior and interior of steel pipes. Suitable for a variety of pipe types, including straight-seam steel pipe and spiral pipe, the line boasts a comprehensive ISO9001-certified quality assurance system, ensuring reliable, end-to-end quality control.
