The Argweld® QuickPurge® Tube, Pipe & Pipeline Inflatable Weld Purge System comprises a tandem inflatable dam system connected by a volume reducing sleeve. Operating temperature 250˚C (482˚F) continuous use and up to 280˚C (586˚F) for short periods. The size of the system to be ordered must correspond with the ID of the pipe being welded. All systems come fitted with PurgeGate® as standard.

The QuickPurge® design works best by keeping the sleeve as short as possible to fast results. With the short sleeve, it is difficult to pull the system through 90˚ bends. In the event that you will need to pull your QuickPurge® system through 90˚ bends, please contact us.

Benefits
Tandem inflatable dam system: This ensures a complete seal around the weld joint, preventing oxygen from entering and causing oxidation.
Volume reducing sleeve: This reduces the volume of the annulus between the pipes, which speeds up the purge process.
Operating temperature of up to 250˚C (482˚F) continuously and up to 280˚C (586˚F) for short periods: This makes it suitable for a wide range of applications.
Comes with PurgeGate® as standard: This prevents the dams from overinflating and bursting, which can damage the system.
Easy to use: The system is designed to be quick and easy to set up, even for inexperienced users.
Fast results: The system can purge a pipe in minutes, which can save time and money.
Can be used in pipes with a maximum bend radius of 1.5 times the pipe diameter: This makes it suitable for a wide range of pipes, including pipes with bends.

FAQs
1. How can Argweld® QuickPurge® help me?

Dramatically reduced welding times achieved. Phenomenal savings in argon. For example, a 36″ (900 mm) pipe joint might take from 4 to 8 hours to prepare and purge properly when using homemade devices such as discs made from cardboard, foam or rubber.

With Argweld® QuickPurge®, it takes as little as 10 minutes which includes placing the system into position, inflating the dams and purging.

2. What range of sizes is available?

6 to 88″ (152 to 2, 235 mm)

3. What is the overall length?

Lengths will vary according to the diameter. The space between the dams is kept very short to minimise inert gas use consistent with the need to provide adequate gas coverage.

4. Can Argweld® QuickPurge® Systems be used for ‘return bends’?

It is necessary to tell HFT® at the time of order, that the QuickPurge® System is required for return bends. We will then manufacture longer collars to provide the necessary space to prevent the dams from being too close to the weld.

5. Are Argweld® QuickPurge® Systems re-usable?

Yes, QuickPurge® II pays for itself in a few welds. QuickPurge® is rugged and can be used for multiple welds.

6. What gases can I use with Argweld® QuickPurge® Systems?

Argon (Europe) and helium (N America) are the most common gases but any gas or gas mix can be used. Argon/hydrogen mixes and nitrogen have been used successfully.

7. What are Argweld® QuickPurge® Systems made from?

Predominantly low vapour pressure, flexible, durable, heat resistant materials selected for longevity.

8. How cost-effective are Argweld® QuickPurge® Systems?

Ask for our return on investment sheet. The savings using QuickPurge® are really stunning.

9. Are Argweld® QuickPurge® Systems resistant to heat?

Yes, QuickPurge® is resistant to the heat of all typical arc welding processes.

Special heat-protected purge systems called Argweld® HotPurge® are available to accommodate pre-weld and post-weld heat treated joints.

Heat Protecting Band accessories are available for Keyhole Tig or Keyhole Plasma welding. Or for any other applications where the material under the weld becomes too hot.

10. How do I measure the residual oxygen content?

Use a dedicated “PurgEye® Weld Purge Monitor®“.

11. How do I position the product in the pipeline?

QuickPurge® Systems are manufactured with high strength pull loops that allow the fixing of pull cords. RootGlo® is a glow sleeve which can be seen readily through the root gap when making open root welds. Exposure to 10 minutes of light provides illumination inside the pipe for up to 12 hours.

12. How long will Argweld® QuickPurge® Systems remain inflated?

Continuous purging will ensure effective sealing and this allows time for post-weld cooling and x-ray or ultrasonic inspection. Deflation is instant once the argon feed hose has been disconnected.
