STANDARD ROLL GROOVE SPECIFICATION NOTES:
COLUMN 1: Nominal IPS Pipe size.
COLUMN 2: IPS outside diameter.
The outside diameter of roll grooved pipe shall not vary more than the tolerance listed . For IPS
pipe the maximum allowable tolerance from square cut ends is 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 leak-tight 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 .
IMPORTANT: Roll grooving of beveled end pipe may result in unacceptable pipe end flare . See column 8 .
COLUMN 4: Groove width.
Bottom of groove to be free of loose dirt, chips, rust and scale that may interfere with proper coupling
assembly . Corners at bottom of groove must have a radius of the following dimensions . For IPS steel pipe, .06R on 3/4 - 11/2”,
.08R on 2 - 6”, .05R on 8” and up .
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 roll grooved – except PVC .
COLUMN 8: Maximum allowable pipe end flare diameter.
Measured at the most extreme pipe end diameter square cut or
