Industrial Endoscope Technology
Equipment composition
Industrial pipeline endoscope is an NDT instrument that integrates light, machine and electricity into pipeline internal quality inspection, detection and analysis. The main configuration includes: camera probe, cable, imaging device.
The endoscope is suitable for rapid video diagnosis of internal corrosion, cracks, blockages or collapse in pipes with diameters ranging from 30mm to 500mm. Due to its special size design, it allows us to easily and accurately observe the inside of the object without destroying the surface of the detected object.
Department surface structure or working condition.
Detection principle
Endoscope inspection is a kind of visual inspection in non-destructive inspection. The endoscope is connected with a camera, video camera or computer to form a camera, video and image processing system to monitor the field of view target and directly reflect the field of view The internal conditions of the target provide accurate information for diagnosis and processing.
Features and advantages
Non-destructive testing: does not change the state of the detected object.
Simple operation: the equipment is small in size, easy to carry, and low in requirements.
Real-time monitoring: high-resolution LCD monitor online imaging, clear and vivid, directly reflecting the problem.
Long effective detection distance: The sight distance can be extended by connecting the probe with the detection line, and the internal conditions of the pipeline can be observed without dead ends.
Built-in storage module: save work records, can capture pictures, zoom in and out, store videos, etc.
Low cost: One-time investment, long service life.
Inspection and problem judgment
The main reason for the failure of the tubing is the unqualified wall thickness caused by partial wear and corrosion. The main reason for the failure of the liner is the scratch of the inner lining, bulging deformation, scaling and waxing, etc. The above problems can be accurately determined through the inspection in the pipeline by the endoscope . The judgment rules are as follows:
crack. When the light beam irradiates the surface of the object to be tested, black or bright lines are observed, and the lines have irregular edges under a certain magnification, it is judged as a crack.
peeling. When the beam is irradiated in parallel, a shadow is observed behind the convex part; when the beam irradiation angle is changed, a clear boundary between the convex part of the surface and the surrounding object to be detected is observed, which is judged as peeling.
Coated anticorrosive rod
Pull lines and scratches. Under the beam irradiation, a relatively regular continuous long line was observed on the surface, and it was judged as a pull line.
The pits are raised. When the light beam is irradiated at a certain angle, it is connected with the boundary of the surrounding object without dividing line. The raised part has bright shadows, and the back shadows are pits.
corrosion. Under the irradiation of the light beam, a blocky, dot-like matte surface is observed, and the slight unevenness is corrosion at a certain magnification.
foreign body. When the beam is irradiated at any angle, objects other than structures that differ from the surrounding basic objects in color and brightness are redundant.
