PQWT PQ325C Large-Diameter Pipeline Inspection Robot for Pipes ≥350 mm

PQ325C and PQ325C+ are high-resolution, multifunctional and high-specification pipeline inspection robots, designed for large-diameter pipelines and complex working conditions.

The product has been significantly improved in imaging clarity, driving flexibility, and environmental adaptability. It supports 4-megapixel high-definition imaging and camera zoom, clearly presenting internal pipeline details and effectively assisting in the identification and assessment of cracks, siltation, deformation, foreign objects, and other issues. With higher protection capability and stronger obstacle-surmounting capability, it can still operate stably in complex environments such as accumulated water, sediment , and uneven pipe bottoms.

Equipped with front and rear dual-camera systems, the front camera supports 180° vertical rotation and 270° horizontal rotation. Together with the rear camera, it  enables comprehensive, three-dimensional inspection inside pipelines, effectively reducing repeated work and blind spots. Two sets of wheels in different sizes are provided and can be changed according to pipe diameter to meet inspection needs for various pipeline sizes.

Application Scenarios

Used for routine maintenance and detection to detect structural defects, weld defects, structural conditions, foreign-object blockage, damage, and other conditions in various pipelines. It can replace manual work in high-risk and difficult inspection tasks, helping ensure that the inside of the pipeline remains unobstructed and safe.

   Sewage leakage detection for environmental protection.  
   Final acceptance inspection of newly built drainage systems.  
   Final acceptance inspection after drainage system renovation or dredging.  
   Inspection where a sewage treatment plant receives excessive unidentified infiltration water through the drainage system or where water-carrying capacity is insufficient.  
   Investigation of pipe siltation, poor drainage, and related causes.  
   Inspection of mixed-flow conditions between directly dischargeable sewage and sewage requiring treatment.  
   Inspection of operating conditions such as pipeline corrosion, breakage, joint misalignment, siltation , scaling, and collapse.  
   Locating hidden points where manholes cannot be located or pipeline routes are unclear due to drainage system or infrastructure construction impact.  
   Inspection of ventilation ducts, trenches, narrow enclosed building spaces, and similar areas.
