Dissolving water soluble purge paper and tape are an economical choice and often the only available solution to a purge problem when GTAW (TIG) welding stainless steel. For example, this is often the case when either the final weld is done or the pipe is being reduced and a dedicated purge system cannot be retrieved.
This product available in rolls and sheets as well as a water-soluble tape in 1″ or 2″ widths for affixing the paper to the inside of the pipe wall. The paper is strong enough to dam argon or any other inert gas while purging. This purge paper is non-toxic and non-corrosive and is simply flushed away with water or steam when the weld is complete. The paper and tape leave no harmful residuals or trace elements in the pipe.
Dissolving purge paper and tape are ideally suited for the manufacturing of process piping for the nuclear, pulp, paper, food, brewery, petro-chemical, chemical, marine, pharmaceutical and computer industries, to name just a few.
