Purge more with Extra Options

Argweld® PurgExtra® Pipe Weld Purging Systems have the advantage of extra gas inlets and multiple exhausts as additional to accommodate high flow rates of purging and exhaust gases.

04W-MultiExhaustPipeWeldPurgeSystem

An equal number of outlets are provided.

Unwanted connections are left closed with the blanking plugs provided.

The Argweld® PurgExtra® Inflatable Pipe Weld Purging System has additional purge hose inlets to allow extra purge gas to be used for welding titanium and other reactive or high specification metal joints.

The additional inlets and outlets provide the possibility to use the cold inert gas to cool weld metal quick for interpass temperature control or other metallurgical treatments that might need record cooling rates. 

Return on Investment (ROI)

All Argweld® Pipe Weld Purging Systems and all PurgEye® Weld Purge Monitors® provide instant Return on Investment.

Purge with High Flow Rates

PurgExtra Pipe Weld Purge System

Tandem Dam based Tube and Pipe Weld Purging System with PurgExtra® from 2 to 24" (50 to 600 mm).

These Argweld® PurgExtra® Inflatable Pipe Weld Purging Systems are particularly valuable for the welding of high specification stainless steel, titanium and other reactive alloys.

As one of the best systems devised for pipe weld purging activity, the Argweld® PurgExtra® Inflatable Pipe Weld Purge System are based on a tandem dam system.

Argweld® PurgExtra® Inflatable Pipe Weld Purging Systems are easy to use and provide a very rapid weld purge.

High quality materials used in these Argweld® PurgExtra® Inflatable Pipe Weld Purging Systems guarantee perfect oxide free weld roots in very fast times.

The volume to purge is minimised resulting in significant savings in both time and the quantity of inert gas used.

Argweld® PurgExtra® Pipe Weld Purging Systems have the advantage of additional gas inlets and exhausts to accommodate high flow rates of purging and exhaust gases.

In addition, these systems have no metal parts exposed, making them ideal for use in the food, semi conductor, chemical and pharmaceutical industries to protect internally polished stainless steel tubes, as well as for all other applications where pipe purging systems are required.

Argweld® PurgExtra® Inflatable Pipe Purging Systems can be used over and over again further reducing manufacturing costs.

All systems include RootGlo®, a centring band which glows in the dark for up to 20 hours after 10 minutes exposure to light and IntaCal®, a unique purge gas release system.

Standard sizes in the range of Argweld® PurgExtra® Pipe Purging Systems are available for immediate delivery.

Tandem Dam Systems with Multi Gas Ports

05W-MultiExhaustPipeWeldPurgeSystem

Argweld® PurgExtra® Inflatable Pipe Weld Purge Systems simplify the process of inert gas purging and are quick and easy to install.

These cost saving systems can be positioned accurately.

The dams inflate instantly with the purge gas line giving a guaranteed gas tight seal for fast purging through the integral gas release valve.

Purging time is a fraction of that required with conventional methods leading to significant savings in waiting costs.

Highly reliable, giving regular and repeatable controlled high quality results.

The PurgExtra® contains quick fit couplings complete with "o" ring for gas tight sealing and stainless steel collet to hold the tube mechanically tight. Now fitted with "Anti-release" circlip to prevent parts accidentally separating inside the pipe.

Use less inert gas. Volume of purge gas used is less than 2% of that required for a conventional purge thus providing important savings in money and time.

Significant cost savings as the volume to be purged is localised.

Heat Covers PurgElite PurgExtraOne or two welds provide payback for the Argweld® PurgExtra® Inflatable Pipe Weld Purging System and cost savings charts are available on request.

Gas pressure control ensures an even positive root bead with no notching.

Manufactured to Nuclear Quality Standards with nuclear approved materials, these systems guarantee bright, shiny, coke and oxide-free welds.

Because Argweld® PurgExtra® Inflatable Pipe Weld Purging Systems have no metal parts exposed, internally polished stainless steel tubes are protected.

Heat Resistant Covers

Heat Resistant Covers are available for PurgElite® and PurgExtra® as an accessory. These covers are available in all sizes within the PurgElite® and PurgExtra® range 1 – 24” (25 – 600 mm).

Manufactured from a robust material, the Heat Resistant Covers protect the inflatable dams at each end of the system, with a temperature range of up to 300ºC (572ºF).

Ties on each Cover ensure they are held securely to the Inflatable Tube and Pipe Purging System. Holes are designed on each Cover for the PurgElite® or PurgExtra® fittings, such as inlet, exhaust and Weld Purge Monitor® connection.

The Heat Resistant Covers are sold as a pair, or can be manufactured as a single unit if required.

Technical Data and Specification

PurgExtra Pipe Weld Purging Systems with Extra Gas Inlets and Multiple Exhausts

Argweld® PurgExtra® Inflatable Pipe Purging Systems are available from 2 to 24" (50 to 600 mm).

High quality circumferential butt-welding of tubes or pipes with other tubes, pipes or fittings, requires inert gas to be used inside the bore to prevent oxidation and notching of the root penetration weld bead.

The tandem based Argweld® PurgExtra® Inflatable Pipe Purging System has been designed specially for this work.

Each system has 2 protected inflatable dams connected by an armoured heatproof spinal tube.

Once ready to start purging, the system is inserted into the bore with one dam either side of the weld joint.

The spinal tube carries the gas to inflate the dams, using a unique IntaCal® System to release the gas gently, to purge the interspace without turbulence.

When the gas connection is made and opened, the dams inflate to form a seal, after which the pressure in the system opens the purge IntaCal®.

Each system can be fitted with PurgeGate® as an accessory. PurgeGate® is a revoluntary control mechanism for pressure and flow. With the use of PurgeGate®, the systems are guaranteed not to burst due to over pressurisation.

RootGlo® is included with every system, after exposure to light for just 10 minutes, RootGlo® with glow inside the tube or pipe for up to 20 hours. An easy positioning device.

The inert gas is then fed into the space between the dams expelling the air through the integral exhaust tubes.

Welding can then be carried out with the inert gas ensuring a clean even penetration bead.

Note:  Welding will be started once the Argweld® PurgEye® 100 IP65 Weld Purge Monitor® indicates the required low level of oxygen has been reached.

Afterwards, the dams are deflated simply by disconnecting the purge gas feed and the device can be easily removed. This uniquely designed system means that only one gas connection is required for both dam inflation and weld purging.

The Argweld® PurgExtra® Inflatable Pipe Weld Purging System has additional purge hose inlets to allow extra purge gas to be used for welding titanium and other reactive or high specification metal joints.

An equal number of outlets are provided. Unwanted connections are left closed with the blanking plugs provided with the system.

Frequently Asked Questions

07W MultiExhaustPipeWeldPurgeSystem

1.0 Can I use an inflatable purge system in a smaller or larger pipe?

In the event that the correct size is not available, adjacent sizes may be usable as there is some crossover in the range of each model. Check the specification sheet.

2.0 What happens with pre-heated pipes?

For sizes of 1" to 6" (25-150 mm), see our heat resistant covers.

For sizes of 8" and above (200-2000 mm) see our HotPurge™.

See Argweld® HotPurge™ Heat Resistant Systems.

3.0 What is the distance between the inflated dams?

The spinal tubes between the dams are of a standard length. A chart is available showing the length for each size of system. They can be shorter or longer, according to customer requirements.

4.0 What happens if one dam is damaged, do I have to purchase a whole new assembly?

No, the quick release fittings allow you to disconnect the damaged dam and replace it.

5.0 Can I weld return bends with the Argweld® Inflatable Tube and Pipe Weld Purging Systems?

Yes. The polyurethane coated nylon covers allow the assemblies to easily slide around bends.

6.0 What is the maximum operating temperature for the standard Inflatable Pipe Purging Systems?

80˚C (176˚F), however heat covers are available, which will increase the maximum operating temperature to 300ºC (572ºF).
