FAQ

Single Ended for Closing Welds!

Argweld® Inflatable Weld Pipe Purging Dams offer a cost-effective alternative to traditional plastic foam or cardboard dams, often hand-made by welders on-site at significant expense. Manufactured from advanced materials with low outgassing rates, these dams are ideal for applications where Argweld® Tandem Pipe Purging Systems or older Purge Bladder Systems are less suitable.

Applications for Single Ended for Closing Welds!

Your Questions Answered

What sizes are the Argweld® Weld Purge Dams available in?

They are manufactured in sizes ranging from 6 to 88 inches (152 to 2,235 mm).

Are the Weld Purge Dams reusable?

They are made from the same rugged material as our QuickPurge® Inflatable Tube and Pipe Purging Systems, allowing for multiple uses.

What are the Weld Purge Dams made from?

They are predominantly made from low vapour pressure, flexible, durable, heat-resistant materials selected for longevity.

How long will Argweld® Weld Purge Dams remain inflated?

Continuous purging will ensure effective sealing, with instant deflation upon disconnecting the argon feed hose.

How do I measure the residual oxygen content?

Weld Purge Dams come standard with an exhaust port to connect a Weld Purge Monitor®, measuring oxygen levels as low as 10 ppm.

How do I remove the Weld Purge Dam from the pipe?

Four pull tags around the circumference allow for the attachment of rope, pull wires, or slings to retrieve the deflated system.

How close can they be set up in relation to the weld?

It is recommended that the Weld Purge Dam be placed at least 4 inches away from the welding zone. The dams are heat-resistant up to 80ºC (176ºF), but argon gas, being extremely cold, will generally prevent overheating.

CLIENT TESTIMONIALS

"The purge meters are second to none."

"I am a huge fan of Huntingdon products and have talked to others over the years about using them. The purge meters are second to none. I own and use regularly my PurgEye 100 and my PurgEye 300. I think somewhere, I still have my original Argweld® MKV monitor, which sadly no longer powers up. I am a scarce breed because I have 3 degrees and a complete academic understanding of metallurgy, but more importantly, welding science; I also have over 20 years of hands-on experience in welding on drill floors, firing lines, and vessel shops. I quite literally have a passion for old-fashioned welding! Excellent product, guys!"

"One of the best, if not the best, residual oxygen detector instruments on the market."

"I believe the PurgEye to be one of the best if not the best, residual oxygen detector instruments on the market with its digital residual oxygen level LED display readouts measuring as low as 0.01% and its large, user-friendly viewing screen making it easier for me to read. I also believe the PurgEye has great accuracy in residual oxygen, with speedy measurements displayed within seconds. The PurgEye is a far cry from the old school homemade 'use a cigarette lighter' to check purge gas flow system."

"Purge monitors are a necessity."

"I can personally vouch for purge monitors. When working with medium to large-diameter exotic pipework, they can prevent you from having a terrible day! I've only used the older model, which was a godsend. Anyone, from the welder who has had to carry out weld repairs due to root weld oxidation (or coking) on such materials, to the directors facing an expensive bill for re-work and possible tarnished company reputation, to the client with their project now running behind schedule - knows exactly what I mean. Purge monitors are a necessity."
