Ceramic composite elbows can be used for pipeline connections and serve as replacement products for stainless steel pipes, ceramic pipes, and cast stone pipes. The dataset includes major raw and auxiliary materials, energy consumption, and waste generated during production; however, infrastructure such as production equipment and factory construction is not included within the system boundary of the dataset. The life cycle inventory is compiled from data sourced from multiple references. The manufacturing process of ceramic composite elbows includes cutting, cladding, beveling, assembly welding, bonding, and inspection procedures.
