Your Questions Answered

How can Argweld® HotPurge® help me?

HotPurge® systems are designed for welding high-strength chrome steel pipe joints at high temperatures. They help achieve zero-color, coke-free welds without defects caused by harmful gases or vapours.

What range of sizes is available?

HotPurge® systems are available in sizes from 6 to 88 inches (152 to 2,235 mm).

What is the overall length?

The dimensions between the dams vary from 28 to 36 inches. The dimensions can be adjusted for specific requirements, such as bends.

Can HotPurge® Systems be used for 'return bends'?

Yes, they can be adjusted for return bends if specified at the inquiry stage.

Are HotPurge® Systems re-usable?

Yes, they are designed for multiple uses as long as they are used within their specification and not damaged.

What gases can be used with HotPurge® Systems?

These systems are intended for use with inert argon gas of at least 99.995% purity.

What are HotPurge® Systems made from?

They are fabricated from high-temperature-resistant materials.

How cost-effective are HotPurge® Systems?

They save costs by localising the purge, reducing inert gas usage, and eliminating waiting time.

How do I measure the residual oxygen content?

Use HFT® Weld Purge Monitors®, such as the PurgEye® 100 IP65 for general purposes or PurgEye® 200 IP65 for more accurate measurements down to 10 ppm.

How do I position the product in the pipeline?

Use the pull loops, which can withstand up to a 1,000 lb breaking strain, to pull the system from joint to joint.

How long will HotPurge® Systems remain inflated?

They remain inflated until the purge gas hose is detached.

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."
