Purging for Pipe Welds - On Corrosion-Resistant Metals.


When welding stainless steel, titanium and other corrosion-resistant materials, creating a perfect weld environment is of the utmost importance, because the desired corrosion resistance depends on it. During welding, the heated weld seam is exposed to air and oxidizes if it is not protected. This oxidation must either be prevented or treated later. Successful welding depends in part on a combination of proper purging equipment and techniques, and these are the focus of this article.

This tool provides a quick and easy method of aligning (prior to welding:automatic or manual) sanitary ferrules and other types of fittings, eliminating the need to pre tack. It includes provisions for ID purging and is adaptable to wide range of ferrules and fitting types and sizes. The aluminum back plate is sized for 1-4 inch tube with a 1/8 inch barb for attaching an oxygen analyzer.

Kit Includes

- 1,1 1/2, 2 , 2 1/2, 3 and 4 inch silicone expanding plugs
