Aquasol I-Purge Modular Inflatable Bladder System
I-Purge Modular Inflatable Bladder System
About
The revolutionary, patent-pending I-Purge Modular Inflatable Bladder System is the most innovative and versatile pipe purging system available. I-Purge creates an impermeable seal to consume the least amount of purge gas during pipe purging and welding, saving time and money, while achieving consistent, high-quality welds.
Manufactured in the USA, this long-term, reusable bladder system enables operators to satisfy a myriad of purge requirements with one interchangeable solution. The I-Purge comes equipped with several highly advanced features such as its Quick Connect Fittings that snap-in place and allow easy assembly and disassembly of components. The I-Purge also features an extended length, high heat resistant harness that allows the bladders to be placed outside the heat affected zone and can also sufficiently accommodate any pre-heating or high heat applications.
These state-of-the-art features allow the operator to create multiple configurations, including a one sided pipe stopper and a reducer. Bladders are available in sizes ranging from 2 to 48″ (51- 1219 mm) and may be purchased either individually or as a complete system, a distinct advantage should additional sizes be desired or a component need replacing.
Ideal for fabrication shops, the I-Purge surpasses existing technology with its advanced design and provides the complete solution for all pipe purging needs.
Features and Benefits
Inflatable Bladders Modules A & B
- Manufactured in the USA from the highest quality materials
- Inflated bladders create an impermeable, air tight seal on pipe wall
- Spark resistant, durable exterior cover
- Heavy-duty interior inflatable bag
- Re-usable, long-lasting solution for purging multiple pipes of the same diameter
High Heat Extended Harnesses
- Internal hose and protective external fiberglass sleeve capable of withstanding high temperatures
- Flexible bridge harness easily navigates through pipes, including elbows and tees over 90°
- Kink resistant hose assures continuous gas supply
- Complete with luminescent indicator for accurate alignment at root gap
- Various lengths of harnesses are available to accommodate heat affected zone (HAZ) during pre-heating and high heat applications
- I-Purge sizes 36″ and greater are equipped with a high flow harness to expedite inflation
Quick Connect Interchangeable Fittings
- Push-button feature enables modules to snap-in-place in seconds
- State-of-the-art technology allows for greater versatility and easy assembly – enabling the user to create multiple configurations
- Easy change and replacement of components to avoid costly re-purchase of complete system, with spare parts available for purchase
- Corrosion resistant proven lock mechanism for secure connection
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
- Low profile relief valve available on 2″ and 3″ models
Inert Gas Diffuser
- Patent-pending technology
- Reduces turbulence by dispersing inert gas equally in all directions within the weld zone, improving weld quality and consistency
Tri-Flow Inner Tubing System (BLUE, BLACK & WHITE Hoses)
Multiple inlet/exhaust ports for faster, more efficient purging
Separate Connections:
BLUE – Inflation of Bladders
Initial function is to inflate bladders then flood 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 Connection
Connect this hose to an Oxygen Monitor, such as Aquasol’s 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 I-Purge
- It is important that bladders be deflated before insertion or removal
- Moderate tension (approx. 5 lbs.) should be applied on pull-wires to prevent sagging of the harness during installation and operation
Carrying Bag
- When welding is complete, bladders can be deflated, extracted, cleaned and stored in the provided carrying bag
- Carrying bag protects the bladder when not in use from dust and debris in most industrial work environments, prolonging life
I-Purge Reducer
- Unlike other models with permanent fittings, a pipe reducer can be easily created by simply connecting two bladders of different, yet similar diameters
- Combine different sizes to create unique pipe configurations
I-Purge Isolator Inflatable Pipe Stopper & Single Purge Bladder
I-Purge Modular Inflatable Bladder System
- The I-Purge Isolator is designed to function as a pipe plug for a wide range of applications, including purging of valves or tanks, as well as non-purging applications such as pipe system sealing for servicing, cleaning and inspection
- Constructed of heavy-duty materials designed to withstand the extreme conditions of the petrochemical, utility and construction industries

How I-Purge Works
I-Purge Modular System Components: Equipped with the most Advanced Interchangeable Components
1. Module A 5. Quick Connection to Module A 9. Inflation & Purge (BLUE) Hose
2. Module B 6. Relief Valve 10. Luminescent Indicator
3. Quick Connection to Module B 7. Direct Purge (BLACK) Hose 11. Pull Loops
4. Fiberglass High Heat Bridge Harness 8. Exhaust Monitor Connection 12. Gas Diffuser
Quick Instruction Guide
1. Ensure 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.
