This video demonstrates how to add new pipe sizes to the Database. It explains the process of adding steel pipe data from a PDF document to a database while creating a new entry with a title and relevant information like unit measurements and maximum operating pressure. This video provides step-by-step instructions on entering the wall thickness, outer diameter, and inside diameter for different pipe sizes using an inch-diameter based table as an example, and how to assign the newly created pipe size to the steel pipe on the flow sheet.
