STANDARD ROLL/CUT GROOVE SPECIFICATIONS

COLUMN 1 - Nominal IPS pipe size. Nominal metric (ISO) pipe size.
COLUMN 2 - IPS outside diameter. Metric (ISO) 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 - 3 1/2" 0.045" for 4 - 6", and 0.060" for sizes 8" O.D. and above measured from true square line. For (ISO)metric pipe, the maximum allowable tolerance from square cut ends is 0.76 mm for sizes 20 mm - 80 mm 1.14 mm for sizes 100 mm - 150 mm; and 1.52 mm for sizes 200 mm and above, measured from the 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. Roll Grooved Pipe: Corners at bottom of groove must be radiused. For IPS pipe, .06R on 3/4 - 1 1/2", .08R on 2 - 6", .05R on 8" and up. For (ISO) metric pipe, 1.5R mm on 20 mm - 40 mm, 2.0R mm for 50mm - 150 mm, and 1.3R mm for 200 mm and up.
Cut Grooved Pipe: Maximum permissible radius at bottom corner of groove is 0.015" (0.381 mm).
COLUMN 5 - Groove outside diameter: the groove must be 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.
COLUMN 8 - Maximum allowable pipe end flare diameter. Measured at the most extreme pipe end diameter square cut or beveled.
