Since 2014, CRALEY Group have been developing and patenting innovative solutions for the development of SMART pipeline Infrastructure focussing on 3 keys ares: CRALEY Sensing, CRALEY Fibre and CRALEY Liner

In-pipe sensing for use in pre-existing or new buried pipelines as well as overground pipelines. The real benefit of CRALEY Sensing, in-pipe sensing fibre, as opposed to an external one, is that you can achieve a greatly improved acoustic coupling between the sensing fibre and the fluid in the pipe, which in turn provides better sensing capabilities. The in-pipe nature of our solution also makes it an obvious choice for buried pipelines.

In-pipe fibre optics for an improved method of fibre optic deployment by using existing pipeline infrastructure. Pipeline networks provide a ready-made conduit for the deployment of fibre optic communication cables, and particularly with potable water, there is a highly interconnected network of pipelines that provides water to almost every household and business; from the reservoir right to the to tap, there will be a pipeline that has the potential to be utilised.

In-pipe Relining for re-lining existing pipelines to extend their service life. The re-lining is achieved with a number of concentric polymer tubes, that are inserted into the existing pipeline, inflated with compressed air and fused together using a patented technique that requires no noxious chemicals, high temperature water, steam or heavy machinery. The liner is friendly to the environment, is BPA free and is manufactured from recycled polymers.
