I-Purge®

MODULAR INFLATABLE BLADDER SYSTEM

US & FOREIGN PATENTS ISSUED & PENDINGCE APPROVED

THE MOST VERSATILE & ADAPTABLESOLUTION FOR PIPE PURGING           

MADE IN THE USA

ABOUT I-PURGE

• 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

1) 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

2) 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

3) 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

4) 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

5) 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

6) 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

7) 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

8) 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

9) 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

10) 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
