REVERSE PRESSURE PLUG
|
Standard Sizes 1-1/4" Thru 12"
The Thaxton Reverse Pressure Plug permits testing in a
relatively small section of pipe. This will avoid filling long
sections of pipe with water in order to hydrostatic test a
particular weld or segment of pipe. Reverse plugs have a
solid stem and are held in place by hardened steel
reverse grips. The seal is made with a Neoprene
ring and all steel parts are plated to resist
corrosion.
The stem of each plug has an internal left hand thread to accommodate installation tools.

LARGE DIAMETER STOPPERS
|
|
PIPE SIZES 20" THRU 30" O.D.
Due to the weight and large size of the parts
the stoppers are furnished with a series of draw bolts used in the expansion of the grips.
These drawbolts allow the installer to expand the grip segments evenly.
This type of stopper is also equipped with a female pipe thread
in the bottom of the mandrel which allows the customer to install
a vent tube, by using a street ell and the appropriate length of
pipe. The vent tube will help to remove pockets of air from the
pipe when hydrostatic testing.

Safety GAG
|
The gag is to be installed after the pipe stopper is in place.
The clamp is tightened on the pipe, with the bull ring located
loosely over the stem. If the chain should tighten, this would
signal the operator to reduce pressure and retighten the pipe stopper.
The pipe clamp also serves to restrict expansion of the pipe.

WARNING: PRESSURE TESTING
CAN BE EXTREMELY HAZARDOUS OPERATION AND SAFETY PRECAUTIONS SHOULD BE STRICTLY ADHERED TO.
