Effect of modifying micro-additions on the corrosion resistance of oil and gas pipeline welded joints

The effect of modifying additions of REE, AEE, and Zr on the corrosion resistance of oil and gas pipeline welded joints is studied. Optimum concentrations are established for micro-additions of cerium, yttrium, calcium, barium, and zirconium to fuzed metal providing good welded joint corrosion prope...

Zusammenfassung:	The effect of modifying additions of REE, AEE, and Zr on the corrosion resistance of oil and gas pipeline welded joints is studied. Optimum concentrations are established for micro-additions of cerium, yttrium, calcium, barium, and zirconium to fuzed metal providing good welded joint corrosion properties. Mathematical models are obtained for engineering and predicted estimates of the service life for welded oil and gas pipelines
