A pipe cleaning device, for water pipes, or pipework in chemical, petrochemical or gas installations has a flexible shaft (2) and multiple resilient discs (4) which are a push fit in the pipe, grouped on the shaft. The device is able to pass around pipe bends by the weight of fluid pressure. Various modes of disc slitting are disclosed. One-piece mouldings and composite versions are described. |
