“ES” ROLL 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 - 31/2” (20 - 90
mm); 0 .045: for 4 - 6” (100 - 150 mm); and 0 .060” for sizes 8” O .D . (200 mm) 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 . 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 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 roll groove must have a radius of the following dimensions . For IPS pipe, 0 .04R on 11/2 - 12” (40 -
300 mm) . For (ISO) metric pipe, 1 .2R mm on 20 - 300 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 grooved .
COLUMN 8: Maximum allowable pipe end flare diameter.
Measured at the most extreme pipe end diameter square cut or
beveled .
