Description
Branch Connection fittings (also known as O'lets) are fittings which provide an outlet from a larger pipe to a smaller one (or one of the same size). The main pipe onto which the branch connection is welded is usually called the Run or Header size. The pipe to which the branch connection provides a channel is usually called the Branch or Outlet size. Branch connections are in all sizes, types, bores, and classes, in a wide range of stainless steel, chrome-moly, and other alloys

General notes:
  • Dimensions: Top Row in Inches / Bottom Row in millimeters.
  • 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.
  • L = Dimensions Center Line of Run Pipe + X (Root Gap) + A (height 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.
