Pipe tools
Choose purge plugs, dual seal purge systems, purge discs and spare parts for controlled back purging of stainless steel pipes and tubes.
The right purge setup helps reduce internal oxidation, control shielding gas and improve the root side of the weld.
How to choose
Choose purge plugs for straightforward back purging where you need a practical seal at each end of the pipe or tube.
Choose a dual seal system when you need a controlled purge zone inside the pipe and want to pull the system into position.
Choose spare purge discs, gas tube, couplings, hose clips, towing wire and small parts to keep your purge system ready for repeat work.

Buying help
Weld purging controls the atmosphere inside stainless pipework during welding. It helps reduce oxidation on the inside of the weld and improves the root side result.
Use purge plugs when you need a practical seal at the pipe or tube ends for straightforward back purging work.
Use a dual seal purge system when you need a smaller, controlled purge zone inside the pipe and want to pull the system through to the weld location.
A smaller purge zone can reduce gas volume, improve control and make the purging process more efficient compared with filling a longer pipe section.
Choose by pipe internal diameter and the size range stated on the purge system or plug set. If you are between sizes, ask before ordering.
Common spares include purge discs, reinforced gas tube, quick-connect couplings, hose clips, towing wire, towing brackets and quicklink carabiners.
Send pipe diameter, material, wall thickness if relevant, pipe length, access conditions and whether you need plugs or a pull-through purge system.
