TABLE 1 – GROOVABLE PIPE LENGTHS
If a pipe shorter than the minimum shown in
Table 1 is needed, if possible, shorten the next
to last piece of pipe enough so that the last
piece of pipe is as long or longer than the mini-
mum length specified in Table 1. See example
below.
Example:
A 20 ft. 4 in. length of 10 in. diame-
ter pipe is needed to finish a section and you
only have 20 ft. lengths available. Instead of roll
grooving a 20 ft. piece of pipe and a 4 in. piece
of pipe, follow these steps:
1.
Refer to Table 1 and note that for 10 in.
diameter pipe, the minimum length that
should be grooved is 10 in.
2.
Roll groove a 19 ft. 6 in. piece of pipe and a
10 in. piece of pipe. Refer to Long Pipe Lengths
below.

NOTICE
Pipe nipples shorter than those shown in Table 1 are
available from Victaulic.
LONG PIPE LENGTHS
With pipe in excess of the maximum length
shown in Table 1, a roller type pipe stand must
be used.
1.
Position pipe and pipe stand in accordance
with Figures 2 and 3.
NOTICE
Figure 2 shows the Victaulic adjustable pipe stand
(VAPS 112). VAPS 112 is suitable for
³⁄₄
- 12" pipe.
Also available is Victaulic model VAPS 224 suitable
for sizes 2 - 24". See Accessories on page 29.
Pipe position will affect pipe flare.
• When pipe end flare is excessive, right-to-left
tracking must be kept to a minimum. It may be
necessary to use less than
¹⁄₂
degree.
• Assembly of couplings on pipe exceeding Maximum
Allowable Flare, Column 8 in the Roll Groove
Specifications charts, pages 35 - 38, may prevent
closure of couplings pad-to-pad, allowing possible
pipe separation, and result in property damage.
• Also, joint leakage may result due to excessive
gasket distortion/damage.
