Source One Environmental supplies three types of circular packer. Radius Packers must be used for the repair of bends. The other types can be used for the repair of straight pipes. In addition, the Pillow Packer can be used to repair non-circular structures – see separate tab.
Standard packer
Each packer covers a small range of pipe sizes. The Pipe Doctor standard range covers pipes from DN35-DN400. The product code indicates the packer sizes: for example the PDSP10/15/15 packer is suitable for DN100 pipes and DN150 pipes, indicated by the first 4 numbers. The overall length of the packer is covered by the last two digits of the product code: in this case 1.5metres.
Wheeled packer
Wheeled packers are available for larger sizes and are more manoeuvrable than Standard Packers, with wheels fitted at both ends of the packer. All wheeled packers within this range have an annular (flow-through) construction to allow water to flow down the centre of the packer when in use. This allows the main pipe to remain in operation during patch installation.
Suitable for pipe diameters ranging from 100mm to 600mm, bespoke and larger sizes are also available on request. The product code also indicates the packer size, for example PDWP10/15/15 is suitable for DN100 & DN150 pipes (first 4 numbers of the code) and is 1.5m long (last 2 digits of the code).
Radius packer
Radius packers are normally only used for radius repairs but certain situations may dictate the use of a radius packer in straight pipes, e.g. restricted access, negotiating bends before the straight pipe etc.
Radius packers are available in two sizes: PDRP10/15 is used for DN100 pipelines and PDRP15/15 is used for DN150 pipes. PDRP225/15 is also available.
