Root Gap - X - "Space" for welding the O'let is raised off the run pipe to establish proper weld gap by placing spacers, e.g. welding rods, under the fitting. This provides a uniform welding gap between the curvature of the run and base of fitting.
X=Root Gap not included in L measure.
L=Dimensions Center Line of Run Pipe to Face of Weldolet.
Bevelled Ends ASME B16.9 and B16.25.
Source comes from Bonney Forge (except the sizes in millimeters).
Weldolet® is a registered name. Another often used name is Welding Outlet.
