Historically, purge chambers for gas-tungsten arc, ( TIG ), welding were typically made of heavy paper or cardboard. Costly in time and effort to remove, they often left dangerous residue in the lines. Current methods such as bladders and cones are expensive and bulky to store or transport. They are also prone to malfunctions, easily damaged and limited in their application. Dissolvo water-soluble purge dams from CMS Gilbreth eliminate the hassles of conventional methods while saving you time and money.

Effortless Removal with Water or Steam

Dissolvo papers and tapes completely disperse in liquid. Made of cellulose polymers and tackified resins, Dissolvo products are simply flushed away with water or steam when the weld is complete. Dissolvo purge dams are quickly and easily removed when no longer needed from even the most inaccessible pipe interiors.

Dissolvo purge papers completely dissolve upon contact with liquid or steam. Non-toxic and non-corrosive, they are environmentally safe.

Easy to Use and Transport

No special tools or training are required to install Dissolvo purge dams. Simply cut, trace, fold and apply. They are also easier to handle and transport than bulky bladders, cones and discs. A small amount of Dissolvo paper will handle an entire day of welding.

More Economical and Worry-Free

Non-disposable purge dams such as cones and bladders are often difficult to remove and expensive to replace. Dissolvo papers and tapes are completely disposable and inexpensive. They also save time and gas. The hassles of lost, damaged or stolen purge dams are eliminated with Dissolvo.

A broad range of Dissolvo products ensures you have exactly what you need to complete any weld. Extremely portable, a small amount of lightweight Dissolvo is enough for a omplete day of welding.

Strong and Reliable

Although Dissolvo materials are disposable, they last as long as needed and are strong enough to dam argon, helium and other inert gases. They can be formed to fit all sizes and shapes of piping and tubing and leave no harmful residue or trace elements in the line. Dissolvo purge dams are also designed not to burst inside pipes, unlike traditional bladders.

Proven Effective

Used successfully for over 20 years in thousands of applications, Dissolvo purge dams are the preferred choice of the welding industry. Today, Dissolvo is at work in nuclear and fossil fuel plants, breweries, processing and chemical plants, offshore drilling rigs, tankers, pipelines, pulp mills, and many other welding sites.

Dissolvo products are easy to install and remove, and they are also designed not to burst inside pipes.

Dissolvo TM is an effective, economical purge-dam material for Tungsten inert gas welding of steel, steel alloy or aluminum pipes. Dissolvo is strong enough to dam argon or helium, and still maintain an oxygen purge.

Easy to use, Dissolvo requires no special tools or training. Simply cut, trace, fold and apply to your pipe. Punch a pinhole in each dam to allow oxygen to escape. When the weld is complete, flush the line thoroughly with water or steam. Dissolvo completely disappears, leaving no residue.

Dissolvo is economical - a small amount lasts an entire day. Dissolvo purge dams are easier to handle and transport than bulky bladders, cones or discs.

Dissolvo is available in sheets, rolls and as pressure sensitive tape. Use Dissolvo tape to hold dams in position or splice sheets together to dam large pipes.

Dissolvo purge-dam paper and tapes are nontoxic, biodegradable and 100% recyclable.
