PurgElite Inflatable Purging Systems
PurgElite inflatable purging systems use tandem dams to contain the weld purge area. Select the model by pipe inside diameter, and specify heat covers, hose extensions and PurgeGate separately.
PurgElite inflatable purging systems create a localized purge space around a pipe or tube weld. Two connected inflatable dams limit the volume that must be displaced with inert gas, supporting repeated fabrication and maintenance work without purging the entire pipe length.

Choose the model by inside diameter
The range covers nominal sizes from 1 to 24 inches (approximately 25 to 610 mm). Use the listed inside-diameter range to identify a suitable model; nominal pipe size alone is not enough to confirm fit. The table also lists the corresponding optional heat-cover part numbers.

Standard system and optional heat protection
The manufacturer lists an 80°C (176°F) maximum operating temperature for standard systems. Optional heat-resistant covers are listed up to 300°C (572°F). A cover rating does not establish the allowable temperature or exposure time for every hose, fitting and component of the assembled system. Confirm the specified configuration and operating limits for the application.
For preheated pipework, review HotPurge heat-resistant weld purge systems. Specify any covers, hose protection sleeves, extensions and feed hoses as part of the quotation; items shown together in photographs are not necessarily included in a standard package.
Options guide: what to specify with your quote
Use this guide with the model table above. Confirm the final configuration and operating limits for the application; photographs may show optional items.
| Option | When to specify it |
|---|---|
| Heat-resistant covers | Select the matching optional HRC part number from the model table when heat protection is required. Confirm the complete system operating limits for the application. |
| Hose protection sleeve | Specify when the planned hose routing or heat exposure requires protection. |
| Hose extension | Specify the required extension when access or placement requires it. |
| Argon feed hose | Specify the required feed-hose arrangement and length with the quotation request. |
| Justram Heavy Duty PurgeGate valve | Optional Justram-customized pressure and flow-control accessory. Include it in the quotation request when a dedicated control accessory is required; confirm the model, hose connections, valve orientation and supplied operating instructions. |
Justram Heavy Duty PurgeGate valve and related configurations
Justram offers the Heavy Duty PurgeGate valve as an optional, Justram-customized pressure and flow-control accessory for PurgElite quotations. It is not included with a standard system. Include it in the request where a dedicated control accessory is required, and confirm the selected PurgElite model, hose connections, valve orientation and supplied operating instructions before use.
For additional gas inlets and exhausts, compare PurgExtra pipe weld purging systems. For larger purge areas and a central sleeve that reduces purge volume, compare QuickPurge III inflatable purge systems.
Application fit guide
Use the measured inside diameter to select a PurgElite model, then describe the joint geometry in the quotation request. The following guide identifies when configuration advice may be needed.
| Application | Selection guidance |
|---|---|
| Straight pipe or tube joint | Select PurgElite by the measured ID range in the model table and confirm the joint layout. |
| 90-degree bend or elbow | Provide the bend geometry and required reach. A suitable flexline length and configuration should be confirmed with the quotation. |
| T-piece, short elbow or dome-end/closure work | Describe the joint and access restrictions. A standard tandem system may not suit the configuration; Justram can review the required arrangement. |
| Preheated pipework or extended heat exposure | Review HotPurge heat-resistant weld purge systems and specify the operating conditions. |
| Repeated larger-bore work in one diameter | Compare QuickPurge III inflatable purge systems where the job benefits from a system selected for repeated work in the same bore. |
Specify the system for your weld
Provide the pipe inside diameter, wall thickness, material, joint layout, access restrictions and any preheat or extended heat exposure when requesting a quotation. For bends, tees, short elbows or dome ends, include a sketch or dimensions and describe access from each side. Confirm the model, hose connections, heat protection and operating instructions for the supplied system. Purge time and gas consumption depend on the installation and the oxygen limit required by the welding procedure.
Choose a monitor with a measuring range suitable for that oxygen limit. Compare the weld purge monitor range; the system and monitor have different functions, and an oxygen reading does not certify the completed weld.
PurgElite selection questions
Should I select by nominal pipe size?
No. Select the model using the measured pipe inside diameter within the listed ID range; nominal size alone does not confirm fit.
Are the accessories shown in photographs included?
Not necessarily. Heat covers, hose protection, extensions, feed hoses and the Justram Heavy Duty PurgeGate valve are specified separately as required for the quotation.
When should I compare another purge system?
For additional gas inlets and exhausts, compare PurgExtra pipe weld purging systems. For larger purge areas and a central sleeve that reduces purge volume, compare QuickPurge III inflatable purge systems.
