Polyethylene lining (PE) can be rapidly installed in a pipeline without significantly reducing the diameter of the host pipe.

The process uses PE pip which has an outside Diameter slightly larger than the inside diameter of the pip to be lined.

During the instillation process, the PE pipe is pulled through a die to temporarily reduce its outside diameter. This reduction allows the PE to be easily pulled through the host pipe by a winch.

When the pulling force has been disconnected, the PE pipe begins to return toward its original diameter. However, just before the PE pipe relaxes completely it presses tightly against the inside of the host pipe, eliminating all annular space and creating a close fit lining.

Any length of pipe can be installed making Rehabilitation easier for long distances. Individual sections and fittings can also be welded together by butt fusion.

Pipe Bursting is one of the most economical Ways to replace a buried Pipeline.

Where a CCTV survey shows that the pipeline Is beyond repair or the system requires the line to be up-sized the client has no option but to replace the pipeline.

Age, together with corrosion and faulty joints are the main reasons for leaking mains in water, sewerage or gas systems.

The direct costs are lower than the traditional costs of dig-and-replace methods.

When time, disruption and restoration are taken into account, pipe bursting is the only logical way for pipe replacement.

With Pipe Bursting, a wide choice of replacement materials is available. Polyethylene, PVC, glass fiber and many types of metal pipes have all been used successfully.

RSAL is currently rehabilitating more than 50 kilometers of water pipelines for the Royal Commission in Jubail using the pipe bursting method.
