Huntingdon Fusion Techniques Ltd. has manufactured a variety of weld purging systems for long tubes and pipes, with inflatable dams that can be kept outside of the heated areas. High-temperature-resistant gas hose material helps ensure that the purge dams stay inflated, firmly sealing the purged void to protect the weld throughout the thermal and weld cycles.
PurgElite® inflatable tube and pipe weld purging systems are available from 1 to 24 in. dia., and QuickPurge® II inflatable tube, pipe, and pipeline weld purging systems are available for diameters from 5 to 96 in.
