Tube Qualify 3D Tube Inspection System for Aerospace Pipelines

Date:2026-03-26

Complex piping systems in aviation (covering fuel, hydraulic, and pneumatic lines) feature numerous components—such as flanges and connectors—and are characterized by diverse shapes and intricate structures, making them critical elements of aviation equipment. Ensuring smooth equipment operation requires extremely high dimensional precision during assembly. Traditional inspection tools and Coordinate Measuring Machines (CMMs) struggle to inspect complex spatial curves comprehensively, efficiently, or accurately; they lack the ability to quantify deviations, offer poor traceability, result in low inspection efficiency, and make 100% inspection of piping products difficult to achieve.


To meet stringent customer production standards, ensure rapid quality inspection and flexible production adjustments, and maximize operational efficiency, an aviation manufacturer selected the XTOP3D Tube Qualify 3D optical tube measurement solution. By simply placing the tube on the workstation, precise measurements are obtained within seconds, enabling rapid comparative inspection of bending parameters—whether XYZ or LRA (YBC)—and the generation of digital inspection reports.

The XTOP3D Tube Qualify 3D tube measurement system is used for in-line inspection and bending analysis of aerospace tubing.


Pain Points in Aerospace Pipeline Inspection


Strict Tolerance Requirements:Tolerances for spatial positioning, bending angles, straight-section lengths, and tube-end flange orientations in aerospace tubing (fuel, hydraulic, and pneumatic systems) often require control within ±0.5mm or even ±0.1mm.

Complex Spatial Geometries:Features such as multiple bends, twists, and compact layouts make comprehensive measurement using traditional inspection tools (templates, calipers) impossible.

Full-Dimensional Inspection:Airworthiness regulations mandate 100% inspection of critical tubing; traditional methods are inefficient and prone to missed defects.

Material Property Challenges:Aerospace-grade tubing is expensive, making physical trial bending costly; furthermore, spring-back characteristics vary and are difficult to predict accurately, necessitating actual measurement feedback for compensation.

Assembly Compatibility:The positions and angles of tube-end interfaces (flanges/connectors) must be precise to avoid installation interference or leakage risks.

Data Traceability:Strict aerospace airworthiness and quality management systems require complete records of the production process and inspection data.

The XTOP3D Tube Qualify 3D optical tube measurement system is specifically designed for the in-line inspection of bent tubes. Utilizing non-contact 3D optical measurement technology and multiple high-frame-rate, high-resolution industrial cameras, it captures precise 3D data from complex tube components and rapidly reconstructs 3D models. The fully automated measurement process offers high speed and high precision. Capable of calibrating tube-bending machines and reverse-engineering initial prototypes, the system enables efficient 100% inspection without the need for custom inspection fixtures, accommodating a wide variety of tube components.
