PIPE PREPARATION
Prepare pipe for roll grooving in accordance with
the Operating and Maintenance Instructions
Manual for the applicable tool being used to roll
groove the pipe. In addition, inspect the pipe
surface for dents or surface build-up where
contact with the ball transfers will occur. The
pipe surface should be free of large dents,
accumulations of dirt, rust, and grime that
may interfere with smooth pipe rotation and/or
traversing.
Pipe with external, axial weld seams can be
supported with Series VAP131R Hydraulic,
Adjustable Pipe Stands. However, the weld bead
must be smooth and rounded and at least three
times as wide as it is high. The weld bead must
not exceed
1/8
inch/3 mm in height.
NOTICE
• Grooving pipe that contains external weld
seams will shorten the life of the ball
transfer units.
INITIAL ADJUSTMENTS
CAUTION
• VAP131 components must be used ONLY
for supporting pipe designated in the
“Pipe Ratings” section of this manual.
• The ball transfers must be installed in
the ball transfer supports.
Failure to follow these instructions could
result in damage to the equipment.
1.
Determine the pipe size to be roll grooved.
Refer to the pipe size label affixed to the
VAP131R and VAP131T (shown below).
Pipe sizes listed on top correspond with
the upper ball transfer location. Pipe sizes
listed on the bottom correspond with the
lower ball transfer location. Make sure the
ball transfer is installed in the appropriate
location on each ball transfer support.

2.
Install the ball transfer assemblies in the
slots marked for the appropriate pipe size.
Make sure the ball transfers are facing
toward the inside of the table and that the
ball transfer assemblies are locked into
position in the slots.
NOTICE
• The ball transfer supports may be placed
in the innermost slots to gain height
clearance when assembling valves and
fittings.
• Friction slides and brakes (accessory
items sold separately) can be used in
place of the ball transfer assemblies to
minimize pipe movement. Friction slides
create slight resistance, while the friction
brakes prevent pipe from rotating freely.
• To accommodate varying pipe diameters,
the ball transfers and ball transfer
supports may be placed in alternate
positions to ensure that the pipe moves
freely and is supported properly.
