(3) Groove Diameter “C” must be of uniform depth around the circumference of the pipe.
(4) Groove Depth “D” is a reference dimension only. The Groove Diameter “C” must be maintained.
(5) Minimum Wall Thickness “T” is the minimum wall thickness that should be roll grooved.
(6) Maximum allowable pipe end flare diameter is measured at the pipe end diameter.

(1) The maximum allowable tolerances for IPS Pipe from square cut ends is:
0.76mm (0.030") for sizes 32mm – 80mm (11⁄4" thru 3");
1.14mm (0.045") for sizes 100mm – 150mm (4" – 6"); and
1.52mm (0.060") for sizes 200mm (8") and above.
(2) Gasket Seating Surface “A” must be free from score marks, ridges, indentations, projections, loose paint, scale, dirt chips, grease, rust, etc. that would prevent a positive seal.
Caution: Pressure performance values shown for GRINNELL couplings on light wall (Sch. 5 & Sch. 10 ISO Metric) stainless steel pipe are dependent on the use of required special rolls for roll grooving light-wall stainless steel pipe. Failure to utilize the required special rolls for roll grooving light-wall stainless steel pipe may result in equipment failure.
