In numerous fields—including aerospace, automotive, and marine engineering—piping systems fulfill critical functions within various subsystems, such as engines, braking systems, and air conditioning units; these functions range from fuel transport to data transmission and cable protection. Consequently, the reliability of these piping systems directly impacts the overall performance and service life of the complete machine or vehicle.
During the manufacturing process of piping components, the bending parameters and process settings of CNC tube bending machines must be adjusted to accommodate the specific material properties of the tubing being used. Therefore, it is essential to conduct trial runs and calibration using sample parts; adjustments are then made based on the results of the bending inspections to ensure that the produced components strictly adhere to all specified tolerance requirements.
Currently, the industry still relies predominantly on traditional mechanical inspection fixtures (specifically, the template-matching method), supplemented by contact-based measurement techniques such as Coordinate Measuring Machines (CMMs) and articulated arms. However, this approach entails time-consuming measurement processes, lacks the ability to quantitatively assess deviations, offers poor traceability, and makes it difficult to implement comprehensive, full-scale inspection for entire production batches. Furthermore, for specialized types of tubing—such as irregularly shaped tubes, elongated tubes, and flexible tubes—the complexity of measurement is significantly heightened, and the resulting data offers only limited utility for optimizing the tube bending process itself.
TUBE QUALIFY
One-Touch Fully Automated Measurement and Inspection
The XTOP3D TUBE QUALIFY 3D Tube Inspection System is specifically designed to overcome the unique challenges associated with measuring various complex bent tubing assemblies. Users simply place the bent tube within the measurement frame—regardless of the tubing material or orientation—and initiate a fully automated measurement and inspection process with the press of a single button. The system rapidly and accurately captures precise 3D data of the bent tubes, capable of simultaneously measuring multiple tubes with high precision and exceptional speed.
The system integrates with TUBE QUALIFY 3D tube bending software; by rapidly reconstructing a 3D model of the physical tube and comparing it against the theoretical 3D model, it quickly performs comparative inspections of bending parameters (XYZ or YBC). Users can visualize out-of-tolerance areas directly within the 3D model, enabling the quantification and correction of deviations. Furthermore, TUBE QUALIFY translates these deviations into specific bending correction values, thereby reducing the number of iterations required during prototype trials, enhancing the setup efficiency of the tube bending machine, and simultaneously ensuring the quality of mass-produced bent tubing.
The XTOP3D TUBE QUALIFY 3D tube inspection system, paired with specialized tube bending software, meets the measurement requirements for a wide variety of tube components—including flexible hoses, free-form bends, variable-diameter tubes, branched tubes, composite tubes, and adapters. With one-touch operation, the system captures professional bending parameters—such as bend point coordinates (XYZ), YBC data, and tube sheath tolerances—thereby streamlining workflows, reducing the skill requirements for operators, and significantly boosting the efficiency of tube inspection.
3D Deviation Display for Bent Tubes
Within the 3D model, locations where the piping exceeds tolerance limits can be visualized; this enables the quantification and correction of detected deviations.
Pipe Bending Alignment Inspection — Excess Material Detection
For pipes lacking a pre-cut allowance, the optimal fitting process does not rely on calculations derived from manufacturing data; instead, the allowance is determined based on quality inspection standards. This ensures that, even after the allowance has been trimmed, the main body of the pipe profile continues to meet the prescribed quality inspection criteria.
Flexible Hose Inspection
It employs non-contact visual measurement technology for pipe bending, making it suitable for the inspection of easily deformable flexible tubes; furthermore, it can automatically segment and merge measurements based on the minimum rigid section length of the pipe fittings.
Free-form Bent Tube Measurement
Reducer Measurement
Independent Process Data
When the bending angle of a pipe reaches 180°, the straight sections on either side of the bend become parallel lines; consequently, they cannot be extended to intersect and determine the bending point. To address this, an alternative approach is adopted: the single large-angle bend is segmented into multiple smaller-angle bends for inspection.
Composite Pipe Tee Measurement
Measure the position and angle of the tee using a straight adapter.
Measurement of Composite Pipes with Ball Heads and Threaded Ends
Measure the composite pipeline end section using a positioning/orientation adapter.
Measurement of Flanged and Flared Composite Pipes
Supports the inspection of flanged, flared, ball-head, right-angle, and threaded ends.
Composite Pipe/tube Measurement
Supports the inspection of branch pipes and bifurcated pipes.
Multi-Tube Simultaneous Measurement
TUBE QUALIFY—a 3D tube bending inspection software solution—communicates directly with tube bending machines. It offers the option to output processing correction and springback compensation parameters, records cumulative correction data, and generates specific correction data based on parameters and material properties, thereby minimizing the time required for tube bending machine setup and calibration. Furthermore, the TUBE QUALIFY system can be integrated with robotic arms, automated loading/unloading racks, and host control systems to achieve highly efficient, automated tube bending inspection.
With nearly two decades of accumulated technical expertise in the field of tube and pipe measurement, XTOP3D has successfully deployed its TUBE QUALIFY 3D optical tube measurement solutions across various sectors—including automotive tube production, aerospace manufacturing, and a wide range of other tube processing enterprises. Moreover, the solution has successfully expanded beyond domestic borders, gaining widespread adoption and implementation across several BRICS nations, where it has been designated as a preferred supplier for tube inspection equipment and has secured numerous bulk supply contracts.
