Make sure you choose the right GRP Pipe

7 November 2013

Purepipe has recently helped Anarget Hydro get back into full power at their Donegal Hydro Operation. Robert Coyne (Anarget Hydro) explains the story:

In March 2013 the Anarget Hydro Project suffered a calamitous pipe failure which caused astronomical damage. The original pipe was sand filled GRP DN600 16 Bar. The damage caused meant replacement of nine lengths of pipe in two different locations. The new pipe was pure GRP DN600 16 Bar. The pipe was supplied by Purepipe from Northern Ireland. The standard connection on those pipes is socket and spigot. But because we were matching new with old of different O.D. and incorporating different gradients we decided to use mechanical couplings. The O.D. was machined to create a smooth spigot for clamping. I have to say the standard of finish on the internal surface was mirror like which is crucial for a good steady output on the turbines. Due to their lightweight but sturdy construction they were very manageable to position in situ. The actual installation of pipes and clamping took a very short time indeed. If you are looking for GRP Pipe I would have no hesitation in recommending Purepipe. I would like to commend Paul Hamilton (Purepipe Business Development Manager) for his advice, service and short turnaround times which were of the uppermost importance.

We would like to thank Anarget Hydro for choosing Purepipe to fix the problems on site with their old sand filled GRP pipe. We hope that the pipeline continues to perform - we are ready to provide further replacement pipes if required.

To would be purchasers of GRP Pipe, perhaps this story gives a cautionary note to those thinking of purchasing sand filled GRP pipe.
