DN800 Pipeline: Definition, Applications & Specifications - Oil & Gas Industry

DN800 is a term commonly used in the oil and gas industry to refer to a type of pipeline or pipeline component. \n\nDN stands for "Diameter Nominal," which is a standardized way of indicating the size of a pipe or fitting. In this case, DN800 means that the pipe or fitting has a nominal diameter of 800 millimeters (or approximately 31.5 inches).\n\nDN800 pipelines are typically used for transporting large volumes of fluids, such as crude oil, natural gas, or water, over long distances. They are designed to withstand high pressure and are often buried underground or submerged in water.\n\nThe specific characteristics and specifications of a DN800 pipeline can vary depending on the application and the company or organization implementing it.
