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.
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
- 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
