LOCALISED PART LINING

LOCALISED PART LINING2018-04-13T10:29:57+00:00

In 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.  Connaught Drains use localised part lining to install a part liner with a resin known as Konodour OMPM.

Service Overview:

This PARTLINER system or localised part lining repair uses a Polyester impregnated corrosion resistant fibreglass insert. It varies in length from 400mm to 1000mm, depending on the length of deformity in the pipe. We prepare the partliner in a truck and place it on a wet out table. A self propelled robot places the packer at the correct position in the pipe where the defect is located. The packer is inflated to the correct pressure dependant on the pipe size, which is usually 0.3m bar. The part liner is left to cure once it reaches the proper pressure. We commence curing of the GRP mat impregnated with Polyester Resin, which takes approximately 1 to 2 hours. The packer is deflated and taken out of the pipeline once the patch is cured.

We carry out localised repairs on pipe sizes ranging from 100mm to 1200mm. The Epoxy component achieves superior sealing on wet surfaces. We have installed these on many different factories  with a range of chemicals entering their lines. This extends the life of the pipe without the need for replacement, and therefore eliminates the expense of digging or relining the entire pipeline.

Advantages of Part Liner Repairs:

  • Installation can be from one access point, thus minimising the need for digging and any unnecessary disruption
  • This method repairs all defects types in most pipe materials. This includes fractures, cracks, infiltration and other defects
  • Our resin resists temperatures up to 80 degrees and also can resist most chemicals that enter lines.
