Part Liner Repairs – Localised Repairs
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. McBreen Environmental install a part liner with a resin known as Konodour OMPM.
This PARTLINER system or localised 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. The partliner is prepared in the truck and placed on the a wet out table. A self propelled robot places the packer at the correct position in the pipe where the defect is located. Once in position the packer is inflated to the correct pressure dependant on the pipe size, which is usually 0.3m bar. Once the proper pressure has been reached the part liner is left to cure. Curing of the GRP mat impregnated with Polyester Resin will commence and is completed in approximately 1 to 2 hours. When the patch is cured the packer is deflated and taken out of the pipeline.
Localised Repairs can be carried out 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 that have all different types of chemicals entering their lines. This extends the life of the pipe without the need for replacement, and eliminates the expense of digging or relining the entire pipeline.
Advantages of Part Liner Repairs:
• Installation can be from one access point, minimising the need for digging and the unnecessary disruption associated with it.
• All defects types in most pipe materials can be repaired using this method. Fractures, cracks, infiltration and other defects have been corrected by using this method of repair.
• The advantage of the resin we use is that it can resist temperatures up to 80 degrees and also can resist most chemicals that enter lines.
You have peace of mind knowing all work carried out is by fully trained and qualified operatives, using the latest technology, and all in accordance with the latest regulations.
