Steel pipe can be coated for corrosion resistance through various methods such as galvanization, epoxy coating, or fusion-bonded epoxy coating. Galvanization involves applying a layer of zinc to the steel surface, forming a protective barrier against corrosion. Epoxy coating involves applying a layer of epoxy resin to the pipe surface, providing a durable barrier against corrosion. Fusion-bonded epoxy coating involves applying a powder coating to the heated pipe surface, which then melts and fuses to form a corrosion-resistant layer. These coating methods help protect steel pipes from the damaging effects of corrosion, extending their lifespan and maintaining their structural integrity.
