Inflatable stopper bags are an easy and cost-effective way to seal a pipe and avoid penetration of liquids, gases or any kind of debris or contamination. They are available in sizes from 2 to 80 in. (50–2,000 mm), but other sizes can be made on request. The inflatable bags can be produced in different designs from a variety of materials, including canvas and polyurethane-coated nylon. Versions with internal spines for better stability of the air bag are also available. — Weldwide Solutions Ltd., Llanelli, U.K.
