PREPARING PIPE FOR
GROOVING
For proper tool operation and production of
grooves that are within Victaulic specifications,
the following pipe preparation steps must be
followed.
Victaulic recommends square-cut pipe for use
with grooved-end pipe products. Square-cut
pipe MUST be used with Victaulic FlushSeal
®
and EndSeal
®
gaskets. For 12-inch/323.9-mm
and smaller pipe sizes, beveled-end pipe may
be used with Victaulic standard and Vic-Flange
gaskets, provided that the wall thickness is
standard wall (ANSI B36.10) or less and that the
bevel meets ANSI B16.25 (37
1/2
°) or ASTM A-53
(30°).
NOTE:
Roll grooving of beveled-end pipe
may result in unacceptable pipe flare.
1.
For 12-inch/323.9-mm and smaller pipe
sizes, raised internal and external weld
beads and seams must be ground flush
with the pipe surface 2 inches/50 mm
back from the pipe ends.
2.
All coarse scale, dirt, and other foreign
material must be removed from the interior
and exterior surfaces of the pipe ends.
CAUTION
• For maximum grooving roll life, remove
foreign material and loose rust from the
interior and exterior surfaces of the pipe
ends. Rust is an abrasive material that
will wear the surface of grooving rolls.
• Replace grooving rolls that show signs of
wear, damage, distortion, or other flaws.
Foreign material may interfere with or
damage grooving rolls, resulting in distorted
grooves and grooves that are out of Victaulic
specifications.
PIPE LENGTH REQUIREMENTS
VE268 tools are capable of grooving short pipe
lengths without the use of a pipe stand. Table 1
identifies the minimum pipe lengths that can be
grooved safely by using Victaulic Grooving Tools.
In addition, this table identifies the maximum
pipe lengths that can be grooved without the
use of a pipe stand. Refer to the “Grooving Short
Pipe Lengths” section for instructions on how to
groove short pipe lengths.
NOTE:
Grooved pipe
nipples, shorter than those listed in Table 1, are
available from Victaulic.
Pipe lengths, longer than those listed in Table
1 (and up to 20 feet/6 meters), must be
supported with a pipe stand. Pipe lengths,
from 20 feet/6 meters up to double-random
lengths (approximately 40 feet/12 meters), must
be supported with two pipe stands. Refer to
the “Grooving Long Pipe Lengths” section for
instructions on how to groove long pipe lengths.
If pipe is required that is shorter than the
minimum length listed in Table 1, shorten
the next-to-last piece so that the last piece is
as long (or longer) than the minimum length
specified.
EXAMPLE:
A 20-foot, 4-inch/6.2-m length
of 10-inch diameter steel pipe is required
to finish a section, and only 20-foot/6.1-m
lengths are available. Instead of roll grooving
a 20-foot/6.1-m length of steel pipe and a
4-inch/102-mm length of steel pipe, follow these
steps:
1.
Refer to Table 1, and note that for
10-inch diameter steel pipe, the minimum
length that should be roll grooved is
10 inches/255 mm.
2.
Roll groove a 19-foot, 6-inch/5.9-m length
of pipe and a 10-inch/255-mm length of
pipe. Refer to the “Grooving Long Pipe
Lengths” section.
