EXPLANATION OF CRITICAL ROLL GROOVE DIMENSIONS FOR
ADVANCED GROOVE SYSTEM (AGS) PRODUCTS
WARNING
• Pipe dimensions and groove dimensions shall be within the tolerances specified in the
tables on the following pages to ensure proper joint performance.
Failure to follow these specifications could cause joint failure, resulting in serious personal
injury and/or property damage.
NOTICE
• Grooving pipe to Advanced Groove System (AGS) specifications enlarges the pipe length by
approximately 1/8 inch (0.125 inch/3.2 mm) for each groove. For a pipe length with an AGS
groove at each end, the length will grow approximately
1/4 inch (0.250 inch/6.4 mm) total. Therefore, the cut length should be adjusted to
accommodate this growth. EXAMPLE: If you need a 24-inch/610-mm length of pipe that
will contain an AGS groove at each end, cut the pipe to a length of 233/4 inches/603 mm to
allow for this growth.
• It is critical to measure the Groove Diameter “C” dimension, along with the Gasket Seat “A”
dimension and the Flare Diameter “F” dimension. These measurements shall be within the
specifications listed in the following tables for proper joint performance.

Pipe Outside Diameter – Nominal NPS Pipe Size (ANSI B36.10) and Basic Metric Pipe Size
(ISO 4200)
– The average pipe outside diameter shall not vary from the specifications listed in the
tables on the following pages (API 5L end tolerance). Maximum allowable pipe ovality shall comply
with the requirements of ASTM A-999 and API 5L. Greater variations between the major and minor
diameters will result in difficult coupling assembly.
The maximum allowable tolerance from square-cut pipe ends is 1/8 inch/3.2 mm
for all sizes grooved to AGS dimensions. This is measured from the true square
line. Any internal and external weld beads or seams shall be ground flush to the
pipe surface. The inside diameter of the pipe end shall be cleaned to remove
coarse scale, dirt, and other foreign material that might interfere with or damage
grooving rolls. The front edge of the pipe end shall be uniform with no concave/
convex surface features that will cause improper grooving roll tracking and result
in difficulties during coupling assembly.
