•
Ensure the
Compression Hex Nuts
⑱
are tightened to the point where the
Spring Plate
Hub
⑳
is in the energized state, flush to the
Retainer Plate
⑰
.
•
Do not over tighten or torque nuts to the point that the
Seal
⑩
starts to swell or extrude over
the OD of the plug.
•
In the “Ready to Install” state (see
Figure 5)
, the GripSafe plug will immediately grip on
the pipe upon insertion.
CAUTION:
Make sure plug is clean of debris and contaminants. Each
Wedge Gripper
⑤
should slide
freely up and down in its slot with a full range of motion and no resistance.
Wedge Grippers
⑤
with
impeded movement due to debris, dirt or contaminants will cause the plug to not grip on the pipe’s
ID which can cause it to eject under pressure, potentially leading to injury or death, material loss,
and/or damage to equipment.
6. Installing the GripSafe DBB Plug
CAUTION:
Ensure pipe I.D. is clean, and loose debris is removed to the deepest point the plug will be
installed into. If the pipe is lined or has an irremovable product,
and
contact USA Industries, Inc.
for support before proceeding
. Failure to do so may impede the wedges ability to grip and cause the
plug to eject under pressure. Be sure to wear proper PPE and follow all site guidelines.
6.1 Insert the GripSafe DBB plug evenly into the pipe.
• See
Table 2
for Operational ID Range and clearance requirements.
•
For using GripSafe
Lifting Device
, see
Section 8
.
•
When the
Gripping Wedges
come into contact with
the pipe I.D., evenly push the GripSafe
DBB plug further into the pipe.
•
A slight rocking motion will assist in
insertion.
•
Once the
Gripping Wedges
have begun
entering the pipe, each will be in
independent contact with the pipe I.D.
Retraction or removal of the plug at this
juncture is not possible unless the
Compression
Nuts
⑱
are loosened. See
Section 7
for
plug removal.
•
Insert plug until the top of the
Spring Plate
Hub
⑳
is at least flush with the end of the pipe (see
Figure 6
).
