Pipe inspection borescope GT-PTZ: the portable HD system with a GFRP (glass-fibre reinforced polymer) cable for NDT inspection of pipes and containers with diameters between 9mm and 800mm, in applications across the energy, petrochemical, aerospace and industrial research fields. Unlike push-rods with a flexible metal cable, this pipe inspection borescope uses a rigid GFRP cable with a diameter of 8.2mm, more resistant to compression, more stable when advancing over long distances and more durable in environments with aggressive chemicals or extreme temperatures.
The 4 interchangeable lenses (8mm, 21mm, 37mm, 49mm metal) have individually documented technical specifications: number of LEDs, LUX brightness, depth of field and minimum pipe diameter per lens, essential information for NDT engineers who select the configuration suited to the inspection protocol. The 8-hour battery and the integrated keyboard complete a pipe inspection borescope designed for long technical audit sessions in industrial installations with limited access. Key Advantages of the GT-PTZ Pipe Inspection Borescope
• Rigid GFRP cable Ø 8.2mm, more durable than metal cable: The glass-fibre reinforced polymer (GFRP) cable is more rigid than conventional metal cable, ensuring controlled linear advance in long pipes without the bend "memory" accumulated by metal cables. The chemical resistance of GFRP allows the use of this pipe inspection borescope in pipes with solvents, dilute acids and hydrocarbons that rapidly degrade metal cables.
• 37mm lens with 100,000 LUX, the brightest in the set: The 37mm panoramic lens with 10 LEDs and 100,000 LUX brightness ensures complete visibility in pipes with biofilm or deposits that absorb light, with infinite 360° rotation, 220° tilt and depth of field from 5mm to infinity, complete coverage of the internal circumference with no blind angle.
• 21mm lens with 14 LEDs and anti-reflection white balance: The 21mm front camera with 14 LEDs and 40,000 LUX has a white balance system that eliminates overexposed reflections from internal metal surfaces, critical in stainless steel pipes or high-gloss alloys where false reflections mask real defects.
• 49mm metal lens, anti-collision for large pipes: The metal body of the 49mm lens withstands impact with internal obstacles, weld burrs and flange joints in industrial pipes of 50–800mm. With 4 LEDs and 40,000 LUX, the 49mm lens delivers the complete image of the cross-section of large-diameter pipes.
• 8-hour battery life, complete sessions without recharging: The 8-hour battery covers a full day of inspection over several consecutive sections without recharging breaks, essential in industrial installations where access to power outlets is limited or where the team works in the open field.
• Customizable 30–120m cable: The length of the GFRP cable is configured from 30m (short indoor inspections) to 120m (large-diameter industrial pipes or distribution networks). The rigidity of GFRP maintains the lens's directional control along the entire cable length, without the lateral "floating" typical of flexible metal cables.
• Integrated keyboard and real-time editing: The physical keyboard allows defect annotation, entry of technical comments and editing of recordings directly on the 7-inch screen in real time, without transfer to an external device and without loss of information at the post-processing stage.
“without transfer to an external device and without loss of information in the post-processing stage.”
• Zoom function and footage counter reset: The optical zoom and the footage counter reset function allow re-referencing of the start position between inspection segments, ensuring footage continuity in sessions with multiple access points on the same section.

Applications: Where the GT-PTZ Pipe Inspection Borescope Is Used
A pipe inspection borescope from the GT-PTZ series is the preferred tool of NDT engineers in sectors with strict documentation requirements and pipes in aggressive chemical environments: the energy and electrical industry, petrochemicals, technical supervision and manufacturing quality. The rigid GFRP cable sets it apart structurally from push-rods with metal cable: chemical resistance, compression rigidity and directional stability over distances of 30–120m are decisive qualities for inspections in industrial process pipes where metal cables fail prematurely.
In the aerospace and military industries, this pipe inspection borescope inspects fuel pipes, engine cooling channels and tubular components in load-bearing structures, applications where the 5mm-to-infinity depth of field of the 37mm and 49mm lenses, combined with the anti-reflection white balance of the 21mm lens, delivers the correct image regardless of the type of internal surface inspected (alloy, stainless steel, composite). Explore the full range of Uzinex industrial equipment for NDT inspection solutions across all categories of pipes and installations.
Research institutes, materials laboratories and quality departments in precision manufacturing use GT-PTZ-type pipe inspection borescope systems for structural integrity audits and verification of manufacturing processes, in line with international non-destructive video inspection standards. The individually documented technical specifications per lens allow precise selection of the configuration compliant with the inspection protocol required by the applicable standard.

Frequently Asked Questions about the GT-PTZ Pipe Inspection Borescope
What sets a borescope with a GFRP cable apart from a push rod with a metal cable?
The GFRP (glass-fibre reinforced polymer) cable has superior compression rigidity compared with a flexible metal cable: it advances in a controlled manner in long pipes without accumulating coils or bend "memory" that deflects the lens off axis. The chemical resistance of GFRP allows the use of this pipe inspection borescope in pipes with solvents, acids and hydrocarbons that attack metal insulation. Push-rods with metal cable are more flexible for bends, but less durable in aggressive chemical environments. Why does the 37mm lens have 100,000 LUX versus the 40,000 LUX of the 21mm and 49mm lenses?
The 37mm lens with 360° panoramic rotation must simultaneously illuminate a complete circumference of the pipe from the inside, a larger surface than the front field of the 21mm lens or than the larger 49mm lens. The 10 LEDs with 100,000 LUX distribute light uniformly across the entire viewed circumference, eliminating the lateral shadow zones that appear with illumination systems concentrated at lower powers. What cable comes as standard and how do I choose the right length?
The standard cable is 30m, extendable to 120m on order. The choice of length depends on the type of installation: 30m for the inspection of components in production workshops and short internal pipes; 60m for service pipes in industrial buildings; 120m for distribution networks and process pipes in petrochemical or energy installations. The rigidity of GFRP ensures the lens's directional control along the entire chosen length. How does the GT-PTZ compare with the GT220 and GM320 for industrial NDT inspections?
The GT-PTZ is the pipe inspection borescope with a GFRP cable and documented per-lens specifications, recommended for industrial NDT audits where the chemical resistance of the cable and the precision of the per-lens optical data are protocol requirements. The GM320 is recommended if the priority is touchscreen, WiFi and 7 lenses for diameters from 8mm. The GT220 excels in all-in-one residential inspections with a spring body design for multiple bends. The lens centralizer: what is it and when is it needed?
The centralizer is an optional accessory that keeps the lens perfectly centred on the pipe axis in pipes with diameters much larger than the lens. Without a centralizer, the lens can rest on the bottom of the pipe and provide an asymmetric image. In pipes with diameters 3–10x larger than the lens diameter, the centralizer ensures uniform documentation of the entire internal circumference, essential for NDT compliance reports.
