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 defined by
site safety rules. Always follow site procedure for safely lifting 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 confirm that the maximum test pressure of your system is subjected to is in accordance with
all applicable industry and site-specific 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 fitting 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.
