Multi-Layer Internal External FBE 3LPE Coating Machinery for Steel Pipe
Product Description
The epoxy powder anti-corrosion process for the inner and outer walls of steel pipes is currently an efficient and reliable solution for pipeline anti-corrosion. The treated steel pipe has significant advantages: its coating not only has excellent corrosion resistance, capable of resisting the long-term erosion of various chemical media such as acids, alkalis and salts, but also has a smooth and dense surface structure, which can effectively reduce the frictional resistance during fluid transportation and improve the transmission efficiency of the pipeline. This type of anti-corrosion steel pipe, with its outstanding comprehensive performance, is widely used in multiple key fields such as long-distance oil and gas pipelines, urban water supply and drainage networks, and industrial fluid transportation.
Internal & External FBE Powder coating
Epoxy powder, as a thermosetting non-toxic coating material, forms a high-molecular cross-linked structure coating after curing, which combines excellent chemical anti-corrosion performance with mechanical strength. Its base layer is bonded and cured on the surface of the steel pipe to form a continuous and dense coating, providing excellent adhesion, chemical corrosion resistance and cathodic disbondment resistance. The polymer adhesive bonds the epoxy powder before gelation and is closely connected with the top layer of polyethylene, making the three-layer structure a unified protective whole.
