VE272SFS Roll Grooving Tool
13
If pipe/tubing 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. Refer to the example below.
EXAMPLE:
A 20-foot, 4-inch (6,2-m) length of
10-inch diameter steel pipe is required to fin-
ish 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
(0,1-m) length of steel pipe, follow these
steps:
1.
Refer to Table 1 on this and the previous
page, 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 "Long Pipe/Tubing
Lengths" section on page 13.
LONG PIPE/TUBING LENGTHS
When roll grooving pipe/tubing that exceeds
the maximum length shown in Table 1, a roll-
er-type pipe stand must be used. The roller-
type pipe stand must be capable of handling
the weight of the pipe/tubing, while allowing
the pipe/tubing to rotate freely.
1.
Make sure the tool is level. Refer to the
"Tool Setup" section on page 7 for leveling
requirements.
2.
When pipe/tubing flare is excessive,
right-to-left tracking must be kept to a mini-
mum. It may be necessary to use less than
1
/
2
º for the tracking angle.
3.
Installation of couplings on pipe/tubing
that exceeds the maximum allowable flare
may prevent pad-to-pad closure of the hous-
ings and/or may cause damage to the cou-
pling gasket. Refer to the applicable “Roll
Groove Specifications” table for details.
4.
If the tool is properly set up in a level
position, but the back end of the pipe/tubing
is higher than the end being grooved, the
pipe/tubing may not track. As a result, exces-
sive flare may occur on the pipe/tubing end.
Refer to the "Tool Setup" section, starting on
page 7, and Figures 1 and 2 below for tool
setup and pipe positioning requirements.
5.
Place the pipe stand at a distance slight-
ly beyond half the pipe/tubing length from the
tool. Refer to Figure 1 below.

6.
Position the pipe stand approximately
1
/
2
º to the left for the tracking angle. Refer to
Figure 2 below.
