Localised Repairs

Localised RepairsIn some cases where there is only a small section of deformed pipe that needs repair it is more cost effective to use a Part Liner rather than reline the entire pipeline. The Localised Pipe Repair system that USSR Ltd. uses is called the Cosmic Part Liner System.


Partliner System

This PARTLINER system uses a Polyester impregnated corrosion resistant fibreglass insert. It can be varied in length from 400mm to 1000mm. Localised Patch Repairs can be carried out on pipe sizes ranging from 100mm to 600mm. The Epoxy component achieves superior sealing on wet surfaces.


Localised Repairs - Adding the linerInstallation can be from one access point. The Partliner is prepared in the truck and placed on the applicator. A self propelled robot places the packer as shown at the correct position in the pipe where the defect is located. When the Partliner Repair System is in position the packer is inflated to the correct pressure dependant on the pipe size. Once the proper pressure has been reached, UV lights inside the packer are activated. Curing of the GRP mat impregnated with Polyester Resin commences and is completed in approximately 7 minutes. The lights are allowed cool down, the packer deflated, withdrawn and preparation for the next repair begins.

All defects types in most pipe materials can be repaired using the Partliner Repair System. Fractures, cracks, infiltration and other defects have been corrected by using this method.
