Industrial pipelines used in sectors such as chemical processing, water treatment and oil and gas routinely suffer from internal fouling due to rust, sludge, scale and chemical deposits, leading to reduced flow capacity, higher pressure losses and possible contamination or failure. Manual internal cleaning of such pipelines is labor-intensive, time‑consuming and often unsafe because it exposes personnel to confined spaces and hazardous media. This work presents the design and partial development of a compact device for internal cleaning of circular industrial pipes in the diameter range of approximately 250–300 mm. The proposed system combines a motor‑driven rotating brush, a wheeled carriage and a water‑spray subsystem to achieve simultaneous mechanical scrubbing and hydraulic flushing of deposits. A prototype chassis, control circuit and cleaning head have been fabricated and tested in a PVC pipe test rig, demonstrating controlled locomotion, brush rotation and water‑assisted debris removal under manual command. The expected outcome of the completed system is an economical, portable and safer alternative to conventional manual cleaning, with potential for future upgrades such as sensor‑assisted navigation, remote monitoring and operation from industrial AC supplies.
