(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.

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.
