Weld Overlay is a process governed by API 5LD. Weld Cladding provides comparable wear and corrosion resistance at a fraction of the cost of solid alloy solutions. Our weld overlay utilizes multiple layers of nickel alloy on a carbon steel backing which is accomplished with minimal diffusion of the substrate.The finished material will greatly increase service life compared to carbon solutions. In addition to pipes and tubes, the technology can be applied to virtually any fitting or piece required for fluid transportation, proving especially useful in sour oil field service. It can be used anywhere increased that corrosion and wear resistance properties are required.
