STANDARD CUT GROOVE SPECIFICATIONS NOTES
*9/16" (14mm) width groove is required in sizes 22-24" (550-600 mm) in order to obtain the maximum allowable pipe end movement listed in
Performance Data Charts. 1/2" (12 mm) width groove will give 1/2 the maximum allowance shown for 22-24" (550-600 mm). For double groove
tool bit information, contact Victaulic.
† Coatings applied to the interior surfaces, including bolt pad mating surfaces, of our grooved and bolted plain end couplings should not exceed
0.010" (0.25 mm). Also, the coating thickness applied to the gasket seating surface and within the groove on the pipe exterior should not exceed
0.010" (0.25 mm).
COLUMN 1: Nominal IPS Pipe size.
COLUMN 2: IPS outside diameter. The outside diameter of
cut grooved pipe shall not vary more than the tolerance
listed. For IPS pipe the maximum allowable tolerance from
square cut ends to 0.030" for 3/4-31/2"; 0.045" for 4-6"; and
0.060" for sizes 8" O.D. and above measured from true square
line.
COLUMN 3: Gasket seat. The pipe surface shall be free from
indentations, roll marks, and projections from the end of the
pipe to the groove, to provide a leaktight seal for the gasket.
All loose paint, scale, dirt, chips, grease and rust must be
removed. It continues to be Victaulic's first recommendation
that pipe be square cut. When using beveled pipe contact
Victaulic for details. Square cut pipe must be used with
FlushSeal® and EndSeal® gaskets. Gasket seat "A" is
measured from the end of the pipe.
COLUMN 4: Groove width. The bottom of groove to be free of
loose dirt, chips, rust and scale that may interfere with
proper coupling assembly. Maximum permissible radius
at bottom of groove is .015"
COLUMN 5: Groove outside diameter. The groove must be of
uniform depth for the entire pipe circumference. Groove
must be maintained within the "C" diameter tolerance listed.
COLUMN 6: Groove depth. For reference only. Groove must
conform to the groove diameter "C" listed.
COLUMN 7: Minimum allowable wall thickness. This is the
minimum wall thickness which may be cut grooved.
