What is the best combination of anti-corrosion materials in anti-corrosion steel pipes

in the increasingly demanding anti-corrosion steel pipe, the selection of anti-corrosion materials has also become diverse, and different anti-corrosion materials have different requirements for steel pipes in different use environments. aside from the premise of the project environment, what is the best anti-corrosion material in anti-corrosion steel pipes?

although both polyethylene and epoxy have excellent corrosion resistance, polyethylene is a thermoplastic material, with good flexibility and bump resistance, due to the poor durability of adhesion between non-polar molecules and steel pipes; epoxy resins are polar molecules with hydroxyl groups. at a certain temperature, the group is easy to react with the steel pipe, and the adhesion is extremely strong, but because it is a thermosetting substance, it is not resistant to bumping. therefore, the combination of the two materials belongs to the current anti-corrosion industry collocation.

these two raw materials are also often seen in the coating material suppliers of anti-corrosion steel pipes. as a manufacturer of anti-corrosion steel pipes, it is enough to see the increase in the demand for anti-corrosion pipes.
