Pipe Purgeing Dams

Patented and practical, EZ Purge is a pre-formed, self-adhesive purge dam that enables operators to save time on weld preparation and improve overall project timeliness. EZ Purge has tapered side walls to fit a variety of pipe schedules and its flat design enables equal distribution of gases across the body of the dam.

Uniquely engineered, EZ Purge comes equipped with EPA approved ZAP® (Zero Air Permeability) technology that maximizes gas retention and reduces gas expenditures. This water soluble purge dam is comprised of Aquasol® Water Soluble Paper and is 100% biodegradable and environmentally friendly. EZ Purge rapidly dissolves, leaving behind no residue in the pipeline.

EZ Purge saves valuable labor hours on dam construction and is easy to use. The operator simply peels, inserts, and presses the purge dam into place. No other product available on the market today can provide such a reliable, efficient, and environmentally sound solution to your pipe purging needs.

Joe Welder™ Performance Tip:

Be sure I.D. of the pipe is clean and free of dirt, grease and grime before installing dams. We suggest using EZ Wipes™ Multi-purpose saturated cleaning wipes designed for welding applications.
