Contract Opportunity Analysis

Fluor Marine Propulsion, LLC, a DOE contractor, is seeking information on inspection solutions for small, compact heat exchangers fabricated from Alloy 625 Inconel using additive manufacturing. The work focuses on identifying probes or other methods that can detect specified flaws in smaller tube diameters than traditional manufacturing allows, both after manufacture and during service. Vendors are asked to address the smallest tube ID they can inspect, the flaw types they can detect, wall-thickness measurement capability, and how tube ID, wall thickness, surface roughness, curved flow paths, irregular shapes, and webbing affect resolution and accuracy. The request also seeks information on inspection techniques such as ultrasonic or eddy current methods, including any development capability for new probes. Responses should be submitted with the completed form and any additional information to John Heckert at John.Heckert1@unnpp.gov.

AI Summary
Fluor Marine Propulsion, LLC is seeking advanced inspection solutions for small, compact heat exchangers (HX) made from Alloy 625 Inconel using additive manufacturing. The primary goal is to identify methods capable of detecting specific flaws in smaller tube diameters (0.100 to 0.400 inches) and webbing, both post-manufacture and in-service. Desired capabilities include detecting circumferential and axial volumetric flaws, cracks, voids, delamination, degradation (pitting, wear), and providing accurate wall-thickness measurements (0.010 to 0.050 inches). The request for information (RFI) asks vendors to detail their inspection probes or methods, specifying the smallest inspectable tube ID, detectable flaw types, comprehensive detection capabilities, inspection techniques (e.g., eddy current, ultrasonic), and how tube ID, wall thickness, and surface roughness impact defect resolution and measurement accuracy. Vendors must also address the ability to inspect webbing, handle curved flow paths, inspect irregular shapes, and provide development capabilities for new probes. Deliverables include a response table for flaw types and detailed answers to technical questions.
