Development of Sour Grade API X60 Steel for LSAW 16” Pipes in the Dos Bocas Refinery Project
Development of Sour Grade API X60 Steel for LSAW 16” Pipes in the Dos Bocas Refinery Project
This study presents the development and qualification of sour‑grade API X60 steel for 16”–24” LSAW pipes for the Dos Bocas Refinery project. Production employed KR desulfurization, vacuum degassing, and strict casting controls to minimize inclusions and segregation. Two chemistries were evaluated: DOE‑1 (w/o Ni/Cu) and DOE‑2 (with Ni/Cu)...
