2. Safety
⚠ Failure to follow proper safety requirements may result in the GripSafe plug failing, which could lead to personnel
injury, material loss, and/or damage to equipment.
⚠ Wear proper Personal Protective Equipment (PPE) when performing any task with the GripSafe plug as dened by
site safety rules. Always follow site procedure for safely liing and operating equipment.
⚠ Never install the GripSafe plug in a position where the Gripping Wedge would be located over weld droop or ridge.
⚠ Never install the Seals or Gripping Wedge over a section of pipe that is missing its interior wall; i.e. weldolet, tee,
etc.
⚠ Use care in the handling of the Wedge Studs. Never beat, hammer, or pry on the Wedge Studs, and never remove
the nut located on the Wedge Studs.
⚠ Pressure testing can be a hazardous operation and safety precautions are important. Never stand or pass in front
of a test plug during installation, testing, and removal.
⚠ Do not make adjustments to the plug, safety equipment, or vessel while the plug is under pressure.
⚠ Do not exceed rated pressure stamped on the plug. Plugs are rated for holding pressure in one direction; never
apply pressure on the non-rated side of the plug.
⚠ Backpressure rating on the references the plugs ultimate holding capacity. Never exceed the pressure capacity of
the weakest component in a pressurized system. Study your system’s components prior to beginning a pressure
test to ascertain and conrm that the maximum test pressure of your system is subjected to is in accordance with
all applicable industry and site-specic standards.
⚠ We recommend using water as the test medium. Before pressurizing the system, vent all gases from the vessel.
⚠ If performing pneumatic testing, all attempts to limit potential damage to personnel or equipment is critical. USA
Industries, Inc. recommends Nitrogen as the medium for pneumatic testing as it does not support combustion.
Follow provisions outlined in ASME PCC-2 Repair of Pressure Equipment and Piping when testing pneumatically.
⚠ Carefully observe the location of the pipe where the Wedge Grippers make contact when performing a hydro test.
If you observe any deformation or swelling of the pipe, stop immediately and slowly release the pressure from the
system. Contact USA Industries, Inc. for further assistance.
⚠ If you hear a popping or clicking sound at any time during a hydro test, stop immediately and slowly release the
pressure from the system. Popping or clicking sounds during hydro testing may be a sign of the Wedge Gripper
slipping, cracking, or one of the plug components failing. Remove the plug from the pipe or tting and inspect for
damage. Contact USA Industries, Inc. for further assistance.
⚠ Make sure the plug is clean of debris and contaminants. Each Wedge Gripper should freely slide up and down in
its slot with a full range-of-motion, and incur no resistance. If you experience impeded movement due to debris,
dirt or contaminants, the plug may not grip the pipe’s ID securely, which can cause plug ejection under pressure,
potentially leading to injury, death, material loss, and/or damage.
⚠ For any questions or concerns, contact USA Industries, Inc. for technical assistance.

• Ensure the Compression Hex Nuts⑱are tightened to the point where the Spring Plate
Hub⑳is in the energized state, ush to the Retainer Plate⑰.
• Do not over tighten or torque nuts to the point that the Seal⑩ 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 Gripper⑤should slide
freely up and down in its slot with a full range of motion and no resistance. Wedge Grippers⑤with
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 Liing 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
Nuts⑱are loosened. See Section 7 for
plug removal.
• Insert plug until the top of the Spring Plate
Hub⑳is at least ush with the end of the pipe (see Figure 6).

FRM-23.1 Rev.B
• If insertion into the pipe proves problematic in the “Ready to Install” state (see Figure 5), it may
be advantageous to insert the plug in the “Not Ready to Install” state (see Figure 4). To do so,
loosen all Compression Hex Nuts⑱to the top of their respective All-read Shas⑪. Care
should be taken to not completely remove the Compression Hex Nuts⑱from the assembly. In
this orientation, the Gripping Wedges will be fully retracted and the plug can be inserted freely
into the pipe.
Caution: In this orientation, it is important to note the plug will not be immediately gripping the pipe
upon insertion. Only aer tightening the Compression Hex Nuts⑱while the plug is in the pipe, to
advance the bottom of the Spring Plate Hub⑳to contact the top of the Retainer Plate⑰will the
plug be securely gripping the pipe. Continue installation with Step 6.2.
TEMPERATURE NOTE:
If welding is to occur while the plug is inside the pipe we recommend that the top of the Spring Plate
Hub⑳be at minimum of 12” into the pipe beyond the location welding is to occur. USA Industries’
Urethane Seals (Tri-Ply™)⑩can withstand 180° continuous and 225° Fahrenheit for short durations.
If high-temperature seals are needed, contact USA Industries for alternative sealing solutions.
Monitoring of pipe temperature at the seal location is recommended to prevent seal failure.
6.2 Evenly tighten the Compression Nuts.
• Using a star pattern (see Figure 7), turn each Compression Hex Nut⑱a maximum of 3 full
revolutions before moving to the next nut. Repeat until 50% target torque is achieved on all nuts,
and then increase to 100% target installation torque and continue torqueing in a star pattern.
Aer completing the star pattern at 100% of the target torque, use a circular pattern to conrm
all nuts are torqued correctly.
• Minimal torque will be required for the rst several passes, but torque will increase notably aer
the Seals⑩begin to compress against the pipe ID.
NOTE: To help center the plug in the pipe it may be desirable to tighten the two bottom-most
Compression Hex Nuts⑱to expand the Seals⑩under them, thereby liing the plug up to center.
A short push of the plug will reset the Wedge Grippers⑤to accommodate the new centered position
respective to the rest of the plug body. Normal installation should commence once the plug is centered.
is may be desirable in the event the plug is noticeably not in the center of the pipe and test pressures
are not achieved while the plug is at Maximum Compression Torque or the plug is not within the 1/8”
concentricity limit if the pipe ID is within 0.200” of maximum range.

6.3 Verify integrity of the Seals⑩.
• If the plug is being used for pressure testing, use proper ttings to install a hydro test
pump to the Backpressure Vent Port⑲; otherwise, install a cap to seal o the system or a
backpressure monitoring tee.
• Increase pressure to 25% of target pressure or 150 psig, whichever is less. Observance of a
pressure drop may not be an indication of leakage. e Seals⑩will creep under pressure
until they are fully seated. is creep will increase the pressure test volume. Depending on
the test volume size this may be by such a trivial amount it will not be seen on a gauge. For
relatively small test volumes a noticeable gradual loss in pressure may be observed during
this creep phase. Seating the Seals⑩is obtained by reapplying pressure until the pressure
becomes stable. is seal creep may also be observed when the system is subjected to the full
pressure. Resolution to the creep is the same at high pressure and while verifying integrity.
CAUTION: If the plug is being used for pressure testing, careful observation is needed on the Wedge
Gripper Nuts③travel. On Figure 8, pressure can be added to the system since the Wedge Gripper
Nuts③are still far from the Spring Plate Halo⑮. On Figure 9 however, no additional pressure can
be added to the system since the Wedge Gripper Nuts③have reached their maximum travel.
CAUTION: Careful observation is needed at the location of the pipe where the Wedge Grippers make
contact while performing a hydro test. If any deformation or swelling of the pipe is observed, STOP
IMMEDIATELY and slowly release the pressure from the system. Contact USA Industries for
further assistance.

CAUTION: If at any time during hydro testing a popping or clicking sound is heard, STOP
IMMEDIATELY and slowly release the pressure from the system. Popping or clicking sounds during
hydro testing could be a sign of the Wedge Gripper slipping, cracking, or one of the plug components
failing. Remove the plug from the pipe or tting and inspect for damage. Contact USA Industries
for further assistance.
• It may be desirable to attach a gauge and vent hose assembly, or a backpressure monitoring
tee, to the Backpressure Vent Port⑲to bleed o any backpressure. e hose should
be long enough to redirect vapor coming out of the vessel to a safe location away from
personnel that may be in the area. A valve may also be attached to this port to allow safe
backpressure removal before plug extraction (see Section 7). If using a backpressure
monitoring tee, it may be useful to have a pressure gauge on the branch side of the tee
while connecting the run side to the Backpressure Vent Port⑲and a ball valve. Further
advantages can be made by attaching a hose to the ball valve on the monitoring tee and
running the hose to vent to a safe location away from workers that may be in the area.
CAUTION: Fast owing gases or liquids through hosing can cause hose whip. Take caution to avoid
this, failure to do so may result in injury and/or equipment damage.
CAUTION: Do not stand directly in front of the GripSafe DBB plug at any time. Installed plugs
should always be treated in this manner irrespective if the plug has backpressure on it or not.
CAUTION: If backpressure develops, constant observation of pressure observed through the use of an
attached gauge and physical observation of pipe integrity is necessary to ensure safety to personnel and
equipment. Any bulging, enlargement or tapering of the pipe is an indication of over pressuring. e
Backpressure Rating listed in Table 1 is for the pressure holding capability of the GripSafe Outboard
Wedge Double Block and Bleed and could be well beyond the system design limitations in which it
is being used to test.

7.1 If using the plug to hydrostatically test a weld, ensure proper Depth of Insertion by
using the following method:
1. Measure the Weld Zone Depth distance from the pipe or tting end to the center of weld
area to be tested.
2. Obtain the Plug Insertion Depth from Table 3 in respect to the Weld Neck Flange being
tested.
3. Subtract the Plug Insertion Depth from the Weld Zone Depth.
4. If the dierence is a negative number, insert the plug while measuring from the pipe or
tting end to the top of the Spring Plate Hub/Halo ⑮/⑳ and stop inserting when the
reading on the measuring tape matches the dierence found in Step 3.
Example: Testing a weld on a 14” Class 150 Weld Neck Flange.
• Weld Zone Depth: 5.00”
• 12” Class 150 Plug Insertion Depth obtained from Table 3: 6.14”
• Weld Zone Depth – Plug Insertion Depth = 5.00 – 6.14 = -1.14
From the calculation, the top face of the Spring Plate Hub/Halo⑮/⑳ should be
1.14” out past the end of the weld neck ange (see Figure 8).
5. If the dierence is a positive number, measure from the pipe or tting end into the pipe
or tting by the dierence found in Step 3 and make a mark on the ID of the pipe or
tting. Insert the plug until the top of the Spring Plate Hub/Halo⑮/⑳ is aligned to this
mark.
Example: Testing a weld on a 14” Class 600 Weld Neck Flange.
• Weld Zone Depth: 8.38”
• 12” Class 600 Plug Insertion Depth obtained from Table 3: 6.63”
• Weld Zone Depth – Plug Insertion Depth = 8.38 – 6.63 = 1.75”
From the calculation, the top face of the Spring Plate Hub/Halo⑮/⑳ should be
1.75” into the weld neck ange’s end (see Figure 9).

CAUTION: Gripping failure may occur if the Gripping Wedges are not fully inserted into the pipe or
tting. If any of the Wedge Gripper’s⑤surface is visible beyond the end of the pipe or tting end,
represented in Figure 11, the GripSafe plug may not hold any back pressure. Advancement of the plug
into the vessel being tested is necessary so none of the Wedge Gripper’s⑤surface is visible beyond
the end of the pipe or tting end shown in Figure 10. Care should be taken to not cover the weld area
with the Seal⑩ as it could render a false outcome of a hydro test. e plug may be out of center with the
pipe. To help center the plug in the pipe it may be desired to tighten the two bottom most Compression
Hex Nuts⑱to expand the Seal⑩under them, thereby liing the plug up to center. A short push of the
plug will reset the Wedge Grippers⑤to accommodate the new centered position respective to the rest of
the plug body.
Normal installation should commence once plug is centered. is may be desirable in the event the plug is
noticeably not in the center of the pipe and test pressures are not achieved while the plug is at Maximum
Compression Torque or the plug is not within the 1/8” concentricity limit if the pipe ID is within 0.200”
of max range.

8. GripSafe DBB Plug Removal
8.1 Depressurize the system through the hydro test pump and drain all water from the
Test Vent Port and Test Fill Port.
8.2 Remove hydro test equipment and or gauges from the Test Ports①.
NOTE: Use caution to ensure the Test Ports①do not become unthreaded or loosened within the
plug during removal of the hydro testing equipment when testing is complete. Failure to do so may
cause internal leaks when the plug is used again. Use appropriately sized wrenches.
8.3 Ensure there is no back pressure on the GripSafe DBB plug.
CAUTION: SLOWLY open Vent Port⑲to relieve any back pressure. Care must be taken when opening
valves or loosening ttings if any inadvertent backpressure was introduced to the vessel. Failure to do
so may result in hazardous pressure ow and/or ttings becoming violently hazardous projectiles that
may damage personnel and/or equipment. If utilizing a backpressure monitoring tee, fast owing
gases or liquids through hosing can cause hose whip. Take caution to avoid this, failure to do so may
result in injury to personnel or equipment.
8.4 Loosen the Compression Hex Nuts⑱in an even star pattern as to not place the whole
load on one bolt.
• If a Compression Hex Nut⑱runs free during loosening, run the nut back to ush with the top of
the Spring Plate. e Seal⑩act as a spring containing a large amount of force, too great for one
All readed Sha⑪to handle.
• Once the seal has broken free from the pipe ID, continue loosening the Compression Hex Nuts⑱
until it is even with the top of the All readed Sha⑪.
NOTE: Do not remove the Compression Hex Nut⑱from the All readed Sha⑪. If this happens,
immediately reinstall the components.
CAUTION: Ensure that all Compression Hex Nuts⑱maintain a load on them during the entire
loosening process. Having all Compression Hex Nuts⑱loose but one, means that a large load is le on
one All readed Sha⑪and the risk of breakage is probable. Once the seals have relaxed enough to
break the seal from the pipe ID the plug is now in a much more relaxed state and Compression Hex
Nuts⑱can be loosened in full.
8.5 Remove the GripSafe DBB plug from the pipe.
• Clean and store for later use or return to USA Industries, Inc.
• Store out of direct sunlight in an area not exposed to above 150⁰F UV. Excessive heat will cause
seal degradation over time.

• Wedge Gripper⑤texture may become packed with pipe scale and rust aer several uses of
the plug. Inspection of this surface aer use is necessary to keep the gripping strength of the
Gripping Wedges at peak performance. To clean, simply use a mild dishwashing soap and a
sti stainless steel bristled brush such as a welding brush. If plugging is persistent, use of a
household rust remover along with a sti stainless steel bristled brush should be sucient.
Rinse plug clean of residual chemicals with tap water and dry thoroughly.
