I Purge and I PurgeX Operation Instructions

Описание: Operation Instruction for I-Purge:

1. Ensure I-Purge http://www.aquasolwelding.com/i-purge is fully assembled (i.e. Modules are securely connected to harness using quick connect fittings).
2. If necessary, connect rope, chain, or wire to the pull loops on the ends of the bladder
modules. This will allow easy insertion and removal of the system.
3. Connect inert gas lines to the BLUE and BLACK hoses.
BLUE gas hose is required to inflate the purge bladders.
BLACK gas hose is optional to expedite the purging process
4. Position the purge unit in the pipe using the luminescent indicator as a guide to center
the system across the root gap
5. Turn the gas supply on to inflate the bladders and purge the weld zone.
Recommended Flow Rates for Purging:
BLUE gas hose should transfer inert gas at 10-32 SCFH (5-15 LPM) for models 2″ – 34″ and 60 SCFH (28.5 LPM) for models 36″– 48″
6. Once a tight seal has been achieved, commence welding while maintaining flow rate.
Recommended Flow Rates During Welding:
BLUE gas hose should transfer inert gas at 15-30 SCFH (7.5-15 LPM)
7. After the weld is complete, turn off the gas supply to deflate the bladders. Once the
heat zone has sufficiently cooled, remove I-Purge from the pipe. Be sure to disconnect
all gas lines and monitoring equipment.
8. Clean I-Purge and store in the provided carrying bag when it is not in use.
Operations Instruction for I-Purge X:
1. Ensure I-Purge X (expandable purge bladders http://www.aquasolwelding.com/i-purge-x ) is fully assembled (i.e. modules are securely connected to harness)
2. If necessary, connect rope, chain, or wire to the pull loops on the ends of the bladder modules. This will allow you easy insertion and removal of the system.
3. Connect inert gas lines to the BLUE and BLACK hoses
4. BLUE gas hose is required to inflate the purge bladders
5. BLACK gas hose is optional to expedite the purging process
6. Position the purge unit in the pipe using the luminescent indicator as a guide to center the system across the root gap
7. Turn the BLUE gas hose on to inflate the bladders and purge the weld zone.
8. Always maintain a consistent flow rate during inflation, purging, and welding.
9.For sizes 2″-36″ BLUE gas hose should transfer inert gas at 30 SCFH (15 LPM) only. For sizes 38″-48″ BLUE gas hose should transfer inert gas at 60 SCFH (28.5 LPM) only.
10. Once a tight seal has been achieved, commence welding
11. After the weld is complete, turn off the gas supply to deflate the bladders. Once the heat zone has sufficiently cooled, remove I-Purge X from the pipe. Be sure to disconnect all gas lines and monitoring equipment.
12. Clean I-Purge X and store in the provided carrying bag when it is not in use.
