Abstract:
1. A two-piece flange adapter for connecting a flanged pipe to a grooved pipe, comprising: at least two flange members, each flange member comprising: first and second flange member ends, the first flange member end having a first planar end surface and the second flange member end having a second planar end surface, the planar end surfaces each disposed in a plane parallel to and passing through a longitudinal axis of the flange member; a flange portion having at least one surface for engagement with the flanged pipe, the at least one surface defining a series of longitudinal bolt holes extending longitudinally through the flange portion; a tongue portion having a least one surface for engagement with the grooved pipe; an inner diameter surface extending between a first terminal end at the first flange member end and a second terminal end at the second flange member end to define a channel configured to support a gasket; a notch at the first flange member end defined by a notch surface adjacent to the first terminal end of the inner diameter surface, the notch disposed between the first planar end surface and the longitudinal axis, the notch having a notch depth extending between the first planar end surface and a terminal end of the notch; and a projection at the second flange member end defined by a portion of the inner diameter surface and a projection surface adjacent to the second terminal end of the inner diameter surface, the projection disposed between the second planar end surface and the longitudinal axis, the projection having a projection height extending between the second planar end surface and a terminal end of the projection, the projection height being less than the notch depth.
