Selection and ordering notes
In a weld neck flange the pipe is joined to the end of the tapered hub with a butt weld. Stress decreases gradually along the hub, which makes it the standard choice for high pressure, high temperature and vibrating lines. The weld is single and fully radiographable.
The hub bore is machined to the pipe schedule, so the schedule must be stated on the order. RTJ faces are frequently specified from class 600 upwards, and gasket and stud selection must follow that form. See weld neck or slip-on for the details.
