One I-Purge X unit can expand to fit multiple pipe sizes, and all pipe schedules that correspond with a pipe’s diameter. An 8″ to 12″ I-Purge X can fit any pipe sizes in between this range. The range of sizes is displayed on Module A of the system. Although I-Purge X is expandable, it is important not to overinflate the bladders as they can burst, causing damage to the unit.

No tools are required when configuring the system. To assemble or disassemble the modules from the harness, simply press on the quick connect fitting at the end of each side of the harness and remove or connect.

The bridge harness is the connecting hose between the two inflatable bladders. It is comprised of a flexible braided fiberglass shielding over a high-heat resistant inner tube.

The central point of the bridge harness is marked with a luminescent indicator to easily align the center of the unit with the root gap. It is important to position the bladders equal distances from the weld joint to prevent over heating of one side, which could rupture or damage the bladder.

Extended length harnesses offer flexibility to extend placement of the inflatable bladders outside the heat affected zone (HAZ) and to accommodate pre-heating (high-heat) welding applications. Extended length harnesses are available in standard sizes including 12″ (305 mm), 24″ (610 mm), 36″ (914 mm), 48″ (1219 mm) and 72″ (1828 mm). I-PurgeX sizes 36″ and greater are equipped with a high flow harness to expedite inflation. Custom lengths are available upon request.

To prevent exposure to the HAZ, use an extended length harness appropriate for the situation. These harnesses are sold separately and are available in many custom lengths.

I-Purge X CAN be used in a pre-heated pipe. For pre-heating and high-heat applications, select an appropriate size of an extended length harness to ensure placement outside of the heat-affected zone (HAZ).
