Weld Inserts

C-22® weld insert rings are used for additional alloying when orbital or manual welding AL-6XN® in the field. For most AL-6XN piping systems, the process of post-weld annealing is not feasible. In order to improve corrosion resistance of these welds the practice of adding an alloy filler is required. The ring must have a higher molybdenum content than the AL-6XN alloy to compensate for alloys dilution on cooling.

CSI stocks a large selection of AL-6XN tubing and fittings for applications that require greater corrosion resistance than 316L.
