PurgExtra Pipe Weld Purging Systems

SKU: APBM0XX

PurgExtra pipe weld purging systems use tandem inflatable dams with additional gas inlets and exhausts. Confirm the bore size, gas connections and heat protection required for your application.

PurgExtra pipe weld purging systems extend the PurgElite family with additional gas inlets and multiple exhausts for applications needing a different purge-flow arrangement. The connected inflatable dams form a localized space on either side of the weld joint.

Select by actual pipe inside diameter

PurgExtra systems use the same bore ranges as PurgElite for the available 2 to 24 inch nominal pipe sizes. Measure the actual inside diameter and match it to the listed range; nominal pipe size alone is not enough to confirm fit.

How PurgExtra differs from PurgElite

Compare the required inlet and exhaust arrangement with the PurgElite inflatable purging system. PurgExtra is a separate system configuration, not simply a spare bladder. Match its connections and model to the intended installation rather than assuming every system uses a single external gas connection.

Positioning and connection features

The listed PurgExtra design incorporates IntaCal gas release and a RootGlo positioning band. Quick-fit connections use seals and retention components to connect the system. Check the supplied configuration and instructions when arranging inflation, purge flow and oxygen sampling.

Hose protection sleeve and PurgeGate valve

Specify a hose protection sleeve when the planned hose routing or heat exposure requires protection. Include the required hose arrangement and length with the quotation request.

Justram offers the Heavy Duty PurgeGate valve as an optional, Justram-customized pressure and flow-control accessory. It is not included with a standard system. Include it in the quotation request when a dedicated control accessory is required, and confirm the selected PurgExtra model, hose connections, valve orientation and supplied operating instructions before use.

Oxygen measurement and related systems

The PurgEye 100 monitor and accessories page provides a monitor option for applications within its measuring range. For lower oxygen limits, pumped sampling or recording requirements, compare the weld purge monitor range. For a central-sleeve purge arrangement, review QuickPurge III; for preheated pipework, discuss HotPurge with Justram.

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. 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.
