QuickPurge III Inflatable Purge Systems
QuickPurge III inflatable purge systems use two dams and a central sleeve to reduce the pipe volume requiring purge gas. Specify pipe bore, joint access, temperature and the required oxygen limit with Justram.
QuickPurge III inflatable purge systems combine tandem dams with a central sleeve that reduces the volume around a pipe weld requiring inert gas. This arrangement is intended for pipe fabrication where purging the full pipe volume would take more gas and time.
Central sleeve, gas release and positioning
The design includes IntaCal gas release and a RootGlo positioning band. The band helps locate the system at the weld area inside the pipe, while the sleeve reduces the space between the dams that must be purged. Inlet, auxiliary and exhaust connections support the required gas and monitoring arrangement; verify the connections on the supplied unit.
PurgeGate is listed by the manufacturer as standard on QuickPurge systems. Follow the applicable instructions for pressure, flow, exhaust and handling. Correct setup and condition remain necessary even with pressure-control features.
Select the diameter and heat configuration
Justram lists this range for nominal pipe diameters from 6 to 110 inches (approximately 150 to 2,790 mm). Manufacturer publications describe different range limits across versions, so confirm the exact model and operating bore range before ordering. State the actual inside diameter and access through bends or fittings.
Specify any optional heat-protection bands and confirm compatibility with the model supplied. For preheated pipework, review HotPurge weld purge systems. Do not treat an accessory heat rating as a rating for every part of a standard assembly.
Confirm purge performance for the application
Purge time, gas use and the oxygen level achieved depend on pipe geometry, system fit, gas delivery and the welding procedure. Use an appropriate monitor to check the purge atmosphere rather than relying on a fixed time or a guaranteed payback claim. See the weld purge monitor range for measurement and sampling options.
