Pipe PreparationSECTION 15: PIPE PREPARATIONGroove DimensionsSTANDARD CUT GROOVESPECIFICATIONS NOTESFor Complete InformationRequest Publication 25.01ODBAExaggerated for ClarityGROOVE DIMENSION NOTES:Column 1: Nominal Pipe SizeColumn 2: Outside DiameterThe outside diameter of cut grooved pipeshall not vary more than the tolerancelisted. For carbon steel pipe the maximumallowable tolerance from square cut endsto 0.76 mm/0.030" for 20 – 90 mm/¾ – 3½";1.14 mm/0.045" for 100 – 150 mm/4 – 6";and 1.5 mm/0.060" for sizes 200 mm/8" O.D.and above measured from true square line.Column 3: Gasket SeatThe pipe surface shall be free fromindentations, roll marks, and projectionsfrom the end of the pipe to the groove,to provide a leak-tight seal for the gasket.All loose paint, scale, dirt, chips, greaseand rust must be removed. It continuesto be Victaulic’s first re<strong>com</strong>mendationthat pipe be square cut. When usingbeveled pipe contact Victaulic for details.Square cut pipe must be used withFlushSeal and EndSeal gaskets. Gasket seat“A” is measured from the end of the pipe.Column 4: Groove WidthThe bottom of groove to be free ofloose dirt, chips, rust and scale that mayinterfere with proper coupling assembly.Maximum permissible radius at bottomof groove is 3.8 mm/.015".Column 5: Groove Outside DiameterThe groove must be of uniform depthfor the entire pipe circumference. Groovemust be maintained within the “C”diameter tolerance listed.Column 6: Groove DepthFor reference only. Groove must conformto the groove diameter “C” listed.Column 7: Minimum AllowableWall ThicknessThis is the minimum wall thicknesswhich may be cut grooved.BCDTSTANDARD CUT GROOVE SPECIFICATIONS – STEEL AND OTHER METALLIC PIPE @1 2 3 4 5 6 7NominalSizemmInchesPipe Outside Diameter O.D.AGasket Seat± 0.76± 0.03Dimensions – mm/InchesBGrv.
