Huntingdon Fusion Techniques (HFT®) has created a series of low cost, but professionally manufactured Weld Purge Dams, using low vapour pressure materials that seal tightly around the circumference of the volume to be purged.
Available for pipe diameters from 6 to 88 inches (150 mm up to 2,235 mm), the HFT Single Ended Inflatable Weld Purge Dams are made of low vapour pressure materials specially selected for optimum weld purging results to provide the lowest oxygen reading in the fastest possible time with the minimum use of expensive argon gas.
