The Relining Process

The Relining process consists of four steps:

Pipelines are hydrojetted using the appropriate hydrojetting tools for the job. This ensures the internals of each pipeline are thoroughly and uniformly cleaned and all obstructions have been removed. Once clean the pipelines are ready to be inspected.

Specific CCTV equipment suited to the application is used to inspect the internals of the pipelines. The footage is recorded in full colour onto DVD and a complete report is created detailing findings. This information may include misalignment or collapse of drains, missing sections, cracks, water ingress, tree root infestation, ageing infrastructure.

Once the report has been compiled a decision can be made by the Asset Manager or client on the course of action required. An estimate will be provided by SA Pipe Relining to reline the pipeline or carry out sectional repairs, ultimately restoring the aging infrastructure to equal or better than original condition.

The liners are prepared and pulled into place. The result; a creation of a smooth, seamless pipeline or sectional repair resulting in a ‘pipe within a pipe’ capable of withstanding pressure and root penetration – due to the seamless and joinless structure and a smooth bore internal where calcification can no longer occur as deposits will not stick to the inner walls of the new epoxy barrier lined pipe.

Solutions:

Thousands of linear meters of pipelines have been restored worldwide using this simple but effective technology. SA Pipe Relining has both the experience, equipment and advanced technical knowledge to meet your specific needs. The applications for relining are endless and regardless of the depth or height of the pipeline or corrosive nature of the environment, SA Pipe Relining has a solution at hand.

Prevents root intrusion in sewer mains and stops leaks

Cured-in-place epoxy lining moulds to the internal diameter of the host pipe creating a structural seamless ‘pipe within a pipe’. This seamless technology prevents any further root intrusion and eliminates water ingress or leakages from the sewer mains by lining over any cracks, misaligned joins or separation of pipe.

Increases Flow Capacity

Newly relined pipelines increase flow capacity due to the new smooth inner lining of the pipelines created by the NU Flow Process. The smoother internal lining prevents calcification deposits from adhering to the inner wall of the pipeline allowing unimpeded flow while minimising the potential of future blockages. This is particularly applicable on Cast Iron, Clay or Concrete Pipes.

No destruction

Using systemised methods SA Pipe Relining is capable of relining pipelines through inspection openings or any form of access to the pipeline. Liners are launched from access points and pulled into position. This approach is non destructive, quick and effective. Mass trench excavation and backfilling, structural damage, re landscaping, traffic tie ups, hazards and environmental damage are non existent in most cases.

No inconvenience or disruption to your routine

The relining process is non intrusive and clean allowing your routine to be maintained with minimal disruption and maximum cleanliness.

No traffic tie ups, expensive road excavation or damage to paths or landscaping

Disruptions to traffic and costly expenses involved in excavations, replacement of pipelines and reinstatement of affected areas as well as the environmental impact associated with this process are costly, time consuming, a nuisance and dangerous. Consider SA Pipe Relining’s expertise in this area when contemplating the alternatives.

Significant cost savings over traditional pipeline replacement methods

The lining process reduces the need for costly excavations and replacement of existing pipelines in conjunction with all the other associated costs involved in that process. Consider the following requirements when evaluating a traditional drain replacement.

Traditional Method
	Council approval or Water Authority approval required
	Concrete cutting, slab or footing cutting, paver removal and/or landscape destruction imminent
	Excavation of existing drain, usually with a backhoe commences, generally a messy, very intrusive and dangerous process
	Existing drain removed
	No use of facilities until new drain has been laid and connected
	New drain installed connecting to existing connections
	Drains require testing
	Water authority inspection required
	Trenches backfilled and compacted
	Concrete and or paving to be reinstated
	Landscape to be reinstated
	Site cleanup

CIPP restores structural integrity of existing pipelines and repairs ageing infrastructure

The lining process enhances the structural strength of the host pipe creating a ‘pipe within a pipe’. The CIPP liner withstands corrosive environments and the test of time. The perfect solution to ageing infrastructure eliminating the need for costly excavation. Liners can be customised to suit many specific needs.

Can perform sectional repairs or mainline relines

SA Pipe Relining’s versatility extends from sectional repairs to mainline relines. Completing 1m long sectional repairs is not uncommon as the need to reline entire lengths of pipeline in order to complete the repair is not necessary. In high flow and demand situations such as mainline repairs, SA Pipe Relining can use a patented Flow-Through system, allowing the pipeline contents to flow through the lining as it is positioned in place and begins to cure. This technology allows the pipeline to remain in use as the lining is installed.

Has the ability to reline Junctions and Tees in one action creating sealed joins

This unique method of CIPP lining goes where no other lining system goes. Its capabilities are endless. The ability to line around Junctions, Tee pieces, bends, changes in direction, changes in pipe size, gullies and floor traps without any joins is just one of the product’s many advantages. No longer is there a need to core out junctions and insert top hats or the like. The lining process ensures that the Junctions, Tee pieces and bends are all formed in one process, ensuring no joins and perfect pressure tight fittings are formed.

Provides a realistic option to drain replacement

The patented Nu Flow Process enables SA Pipe Relining to provide its customers and clients with an option. Lost productivity on workshop floors, downtime created in factories, businesses and the like through disturbances associated with pipeline replacements, continual blockages or obstructions are no longer necessary with the implementation of the lining process.
