The maximum allowable tolerances for IPS Pipe from square cut ends are: Sizes 1 to 3 (DN25 to DN80) 0.030 inch (0,76 mm) Sizes 4 to 6 (DN100 to DN150) 0.045 inch (1,14 mm) Sizes 8 to 24 (DN200 to DN600) 0.060 inch (1,52 mm) Sizes 26 to 42 (DN650 to DN1050) 0.125 inch (3,18 mm)


Gasket Seating Surface “A” must be free from score marks, ridges, in - dentations, projections, loose paint, scale, dirt chips, grease, and rust that would prevent a positive seal. •  Groove Diameter “C” must be uni - form depth around the circumfer- ence of the pipe. •  Groove Depth “D” is a reference dimension of the distance from the pipe outer surface to the groove bottom, with regards to groove concentricity about the pipe. This dimension is a reference only. The actual dimension “C” must be main - tained. •  Minimum Wall Thickness “T” is the minimum pipe wall thickness that should be roll or cut grooved. •  Maximum allowable pipe end flare diameter is measured at the pipe end diam

Production process

Grooved pipes and fittings provide an economical and efficient method of joining pipe in mechanical building sevices. The grooved piping system joins to - gether two pipe ends by using a cou - pling that is seated in grooves at the end of each pipe. When the coupling is assembled, the coupling keys engage the grooves around the circumfer - ence of both pipes, providing a secure connection. There are two types of grooving: roll grooving and cut grooving. Roll groov - ing uses a special machine that ro - tates the end of a pipe through a roll set, displacing the metal and forming a groove on the outside surface of the pipe. Roll grooving is limited to use with pipe having a hardness value of HB180 or less. Roll grooving can be ac - complished on carbon steel, stainless steel, copper, and aluminum. However, care must be taken to use the proper equipment and roll sets (which may vary with piping material) to create the groove. Consult the grooving machine manual or roll set instructions for fur - ther information. If necessary, contact GRINNELL for assistance. Cut grooving is performed by turning the pipe on a lathe, removing metal from the outside surface of the pipe to create the groove. Cut grooving is intended to be used with Schedule 30 and heavier wall pipe. Refer to Figure 2, “T” Minimum Wall Inches (mm)

Roll Groove

Roughly 90 percent of pipes grooved today utilize roll grooving technology due to the ease of the grooving process while maintaining optimal joint performance. The pipe can be roll grooved in 30 to 40 seconds per square inch compared to one minute per inch using a cut groove. The roll grooving process also removes the need for cutting oil and the hassle of cleaning up the metal shavings that are removed from the pipe during the cut grooving process.

Cut Groove

While roll grooving is very popular, the tried and true cut groove provides very useful in many situations. For example, if the pipe wall is too thick-cut grooving the pipe will provide a more reliable groove. Or if the pipe is internally lined or coated, cut grooving is recommended to keep the integrity of the lining and coating. Even the pipe material can dictate the groove style, some material of pipe must be cut grooved. Cut grooves provide additional engineering advantages, offering twice as much built-in movement compared to roll grooved pipe ends. Regardless if you choose to roll groove or cut groove, Victaulic offers a solution to your pipe joining needs, with the confidence of 100 years of innovation behind it.
