This table is applicable only to ANSI piping and is based upon the following material grades. Refer to the appropriate international
standard for other systems.
Steel – Brinell Hardness Number (BHN) of 180 BHN and less.
NOTE:
When roll grooving steel pipe at or near the maximum rated
thickness, the pipe must not exceed the yield strength of API-5L Grade “B”, ASTM Grade “B”, 150 BHN maximum.
Stainless Steel – Types 304/304L and 316/316L
Aluminum – Grades 6061-T4 and 6063-T4
PVC Type I, Grade I (PVC 1120)
PVC Type I, Grade II (PVC 1220)
PVC Type II, Grade I (PVC 2116)
* All minimum and maximum wall thicknesses are nominal
