About

• The Opti-Purge Inflatable Purging System
  increases productivity when welding large
  diameter pipes 48? to 84? (1219 mm to 2133 mm) of
  various materials including stainless steel,
  titanium, nickel and several other metals and
  alloys.
• The unique one-piece design of Opti-Purge
  consists of two outer rings and a hollow
  connector. The unit is easily and quickly
  inflated to create an impermeable seal within the
  pipe wall. The hollow connector dramatically
  reduces the amount of inert gas needed to purge
  the weld zone, saving both time and money. The
  exterior of the hollow connector consists of high
  heat resistant material that can be exposed to
  temperatures up to 1004F (540C).

• A reflective strip on the hollow connector
  conveniently indicates the center of the
  Opti-Purge, allowing for fast and accurate
  alignment of the system.
• The Opti-Purge is the ideal solution for welding
  large pipe rapidly, requiring minimal preparation
  for maximum results.

Features and Benefits

• Inflatable Structure
• Flexible, lightweight structure
• Inflated rings create an impermeable, air tight
  seal on pipe wall
• Re-usable, long-lasting solution for purging
  multiple pipes of the same diameter
• High Heat Resistant Hollow Connector
• High heat resistant, durable exterior fabric can
  be exposed to temperatures up to 1004F (540C)
  to accommodate heat affected zone (HAZ)
• Supportive rods extend down length of hollow
  connector to maintain structural integrity
• Complete with luminescent indicator for accurate
  alignment with root gap

• Proprietary Relief Valve
• Factory pre-set relief valves allow for precise
  flow rates while minimizing set-up time and
  reducing gas consumption
• Aids in maintenance of optimum seal on pipe wall
• Prevents risk of over inflation
• Tri-Flow Inner Tubing System (BLUE, BLACK WHITE
  Hoses)
• Multiple inlet/exhaust ports for faster, more
  efficient purging
• Separate Connections
• BLUE  Inflation of unit
• Initial function is to inflate the unit by
  allowing gas to flow into the internal tubing
  system. Then it proceeds to flood the weld zone
  with noble gas.
• BLACK  Increase Gas Distribution Within Weld
  Zone
• Designed to expedite purging, the secondary
  (BLACK) purge hose is used to flood the weld zone
  with inert gas and evacuate oxygen at a faster
  rate.

WHITE  Exhaust ConnectionConnect this hose to
an Oxygen Monitor, such as Aquasols PRO OX-100
that obtains readings down to 100 PPM (0.01),
for continuous or spot monitoring of oxygen in
the weld zone Pull Loops Strong pull loops can
be connected to a rope or chain to insert or
remove the Opti-Purge Moderate tension should be
applied on pull-wires to prevent sagging of the
harness during installation and operation

How Opti-Purge Works
1. Using the pull loops, position Opti-Purge in
the pipe so that the reflective, glow tape
portion in the center of the unit is aligned with
the root gap 2. Connect inert gas lines to
the BLUE and BLACK  hosesBLUE gas hose is
required to inflate the purge bladdersBLACK gas
hose is optional to expedite the purging
process 3. Turn the gas supply on to inflate the
unit and purge the weld zoneRecommended Flow
Rate for Purging150 CFH (70 LPM) 4. Once a
tight seal has been achieved, commence welding
while maintaining flow rate 5. After the weld is
complete, turn off the gas supply to deflate the
unit. Once theheat zone has sufficiently cooled,
remove Opti-Purge from the pipe. Be sure to
disconnectall gas lines and monitoring
equipment. 6. Clean Opti-Purge and store in area
away from hazardous and sharp objects
