A method to improve corrosion, abrasion, and fire resistant properties of structural components for use in oil, gas, exploration, refining and petrochemical applications is provided. The structural component is suitable for as refinery and/or petrochemical process equipment and piping, include but are not limited to process vessels, transfer lines and process pipes, heat exchangers, cyclones, and distillation columns. The method comprises providing the structural component with a plurality of layers, a corrosion resistant layer in contact with the corrosive petroleum products comprising a material selected from amorphous metals, ceramic materials, or combinations thereof; a structural layer; and an outer layer comprising a fire resistive material. In one embodiment, the structural component is further provided with at least another layer selected from a metal sheeting layer, an adhesive layer, and a containment layer. The structural component is characterized as having excellent corrosion/abrasion/erosion properties and fire-resistant properties.
