Description

As published on SAM.gov.

The Buyer is currently investigating small, compact heat exchangers (HX) fabricated by additive manufacturing (AM) using Alloy 625 Inconel. Inspection solutions (e.g., probes or other methods) are needed for smaller tube diameters than those typically used in traditional manufacturing. This scope of work seeks to obtain information on inspection capabilities at smaller tube sizes.  While ultrasonic (UT) immersible probes have been previously considered, any method capable of detecting the specified flaws of interest will be evaluated.  Additional information in attached problem statement. 

Please submit completed form and any additional inforamtion at below contact.
