Foam Purge Dams, Purge Plugs and Foam Pigs

Used in tube and pipe welding, foam purge dams isolate the weld area, ensuring a quality weld while minimising the amount of gas required in the weld zone, in turn saving time and money on the job.

Purge dams are a simple, effective and economical alternative to bladders and baffles. They can save significant cost and time on the job for contractors and for large projects. 

Incorporating layers of both open cell and closed cell flexible foams, the dams can be compressed and inserted into the pipe, providing a safe barrier to the movement of air or gas into or out of the welding zone.

Foam Sales' dams, plugs and pigs can be custom-made to your size and design requirements. Some examples of previous jobs are pictured here.

Please contact us for a quote on your custom foam purge dam, plug or pig. Refer to schedule of Standard Pipe Sizes for dam diameters. Dams will typically be a few millimetres larger in diameter than the internal diameter of your pipe.
