Aquasol’s Opti-Purge increases productivity in welding pipes up to 84″ in diameter


The Opti-Purge’s unique, one-piece design consists of two outer rings and a hollow connector that quickly inflate to create an impermeable seal within the pipe wall.

The Aquasol Corporation has designed the all new Opti-Purge® Fast Inflatable Purge System to increase productivity when welding pipes 48–84” (1219–2133 mm) in diameter.

In order to facilitate rapid purging of larger sizes pipes, the Opti-Purge is equipped with a tri-flow tubing system. This unique configuration includes a main hose that inflates the bladders with inert gas. An additional hose expedites gas and an exhaust connection hose monitors gases to ensure an O2-free environment.

The exterior of the unit’s hollow connector consists of high heat resistant material that can be exposed to temperatures up to 1004°F (540°C) to accommodate heat affected zone (HAZ). A reflective strip on the hollow connector conveniently indicates the center of the Opti-Purge, allowing for fast and accurate alignment of the system. Moreover, the hollow connector itself dramatically reduces the amount of inert gas needed to purge the weld zone by occupying space within the chamber, saving both time and money.
