STEEL PIPE AND ALL MATERIALS
GROOVED WITH “ES” ROLLS
“ES” ROLL GROOVE SPECIFICATIONS NOTES
COLUMN 1:
Nominal IPS 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
" (26.7
- 101.6 mm); 0.045: for 4 - 6" (114.3 - 168.3 mm); and 0.060" for sizes 8" O.D. (219.1 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 26.7 - 88.9 mm; 1.14 mm
for sizes 114.3 - 168.3 mm; and 1.52 mm for sizes 219.1 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.
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 be radiused. For IPS pipe, 0.04R on 1
¹⁄₂
- 12" (48.3 - 323.9 mm). For (ISO)
metric pipe, 1.2R mm on 26.7 - 323.9 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.
