16.1 Transfer liquid nitrogen into the clamp using the connected hose. Ensure there is no
misalignment between the hose and the clamp to prevent leakage of liquid nitrogen.
17. Check the formation and integrity of ice plugs using a laser temperature gun After confirming
that the ice plug is fully formed, drain off the pipe medium at the end of the pipeline and verify
the pressure in the pipe is reduced to atmospheric pressure (no pressure).
18. Proceed with the necessary isolation work.
19. Note: All work should be carried out at least 500mm away from the ice plug. If slight melting of
the ice plug occurs, connect a plastic hose to the drain point on the pipe and discharge the
pipe medium to the nearest drainage point/ floor trap.
20. To start necessary blind off for the pipe:
a. Electrical cutter will be used to cut off existing pipe.
b. Existing pipe will be welded with a blind flange to Cap-Off
c. Ensure Cap-off is done properly to prevent leakage
21. After completing the isolation work, drain the residual pipe medium in the pipeline.
22. De-freeze the ice plug and drain the freezing clamp.
23. To prevent air lock, open the vent valve on top of the pipe and purge the system of air. Air lock is
released while de-freezing.

requirement the design pressure of the line is 1.5 time testing pressure, 1 bar, Install a minimum of two
pressure gauges one at higher point and other at lower point. Pressure gauges must be calibrated and
must have validity of minimum six months. Pressure gauges rating must be three times testing pressure.
Counter check all gaskets, test blinds, bolt and nuts had been properly installed. Water filling shall be
conducted at the lower point and Ensure all other nozzles shall be closed with suitable blinds, pipe will be

shall be done in the presence of the client’s representative, the required test pressure shall be maintained
for not less than 30 minutes, Eye protection shall be worn all time during leakage inspection. Safety
barrier shall be provided and only qualified personnel shall be authorized to enter the testing areas.
Sufficient number of warning signboards shall be displayed, Bleed the line to correct test pressure if the
pressure increases, after inspection of line and pressure holding is completed, open the vents gradually
until the pressure goes down to zero.

After completing the mechanical installation work, check the pressure gauges and make sure it's in
the same pressure before de-freeze the ice plug and drain the freezing clamp.To prevent air lock,
open the vent valve on top of the pipe and purge the system of air. Air lock is released while de-
freezing.
