Pipe Relining Equipment Contractors Use

Pipe Relining Equipment

Pipe Relining is growing in popularity due to its efficiency in clearing blocked and broken drains then providing a permanent repair to the pipeline. This can all be achieved using existing access points to the drain network and does not require the traditional costly excavation methods.

What takes Pipe Relining from theory into practice is the equipment, tools and processes that is used by the contractor. Let us take a look at the key pieces of Pipe Relining Equipment used when repairing pipes:

Pipe CCTV Camera
The Pipe CCTV camera is either pushed or remote controlled down the pipe. This allows the contractor to visually inspect the interiors of pipelines. This is a form of non-destructive testing and allows the contractor to provide an assessment of the pipeline and visually see where and what the problems are inside the pipe. Common problems include joint displacement, broken pipe, blockages and root intrusion. The contractor can then provide the cause and location of the fault inside the pipeline.

Hydro Jetting
Hydro jetting is a method used by contractors to clean clogged or blockages inside pipelines. A blast of water at very high pressure is sent into the pipelines that will penetrate through the blockages inside the pipeline. If there is root intrusion a concentrated blockage the contractor will repeatedly hydro jet that area until the blockage is cleared. The hydro jetting hose has a special adapter or connector that can easily connect different penetration jetting nozzles. The are numerous nozzles to choose from and using the correct jetting nozzle for different blockages and pipes is key. This is one piece of pipe relining equipment used to clear blockages, there is also mechanical tooling available the contractor can use.

CIPP Repair Process
There are several Cured-In-Place Pipe repair process available to the contractor. The most common are either a Pull-In-Place System or Inversion. The contractor will use a resin-saturated felt tube made of PET, fibreglass cloth or a number of other materials suitable for resin impregnation. The tube is either inverted or pulled into a damaged pipe and the resin impregnated tube or sleeve is cured hard. This provides a structural repair the the fault inside the pipe and the pipeline is placed back into service. The chosen CIPP repair process and type will determine what other Pipe Relining Equipment the contractor requires.
