Grinnell Grooved Standard Specifications
Roll and Cut Groove for Steel Pipe
Technical
Data
1- The maximum allowable tolerances for IPS
Pipe from square cut ends is:0.030" (0.76mm)
for sizes 1 1 /4" thru 3"; 0.045" (1.14mm) for
sizes 4" thru 6"; and 0.060" (1.52mm) for sizes
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.
3- Groove Diameter “C” must be 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.

General Notes: It is the Designer’s responsibility to select products suitable for the intended service and to ensure
that pressure ratings and performance data is not exceeded. Always read and understand the installation
instructions (IH-1000). Never remove any piping component or correct or modify any piping deficiencies without
first depressurizing and draining the system. Material and gasket selection should be verified to be compatible
for the specific application.
