Metal lubricants are used for lubrication treatment before steel pipe deformation and are primarily composed of sodium fatty acids. The dataset includes major raw materials, auxiliary materials, and energy used in the production process; however, infrastructure such as production equipment and facility construction is not within the system boundary of the dataset. The life cycle inventory is compiled from data obtained from multiple sources. The manufacturing process of metal lubricants includes mixing, homogenization, degassing, filtration, and filling.
