Rehabilitation with HOBAS NC Line

During the contacts with the maintenance department of SMAT the possibilities of relining with HOBAS CC-GRP Pipe Systems was emphasised, for both circular and non-circular shapes. In the municipality of Turin and Venaria the rehabilitation of an egg-shaped pipeline of approx. 536 m was necessary. 136 m of that pipeline were close to collapse. With the common effort of HOBAS Organizations, the advantages of HOBAS NC Line were discussed and comprehensive information provided. The meeting was successful and, although HOBAS NC Line relining technique is totally new for the Italian market, the customer was convinced. The price of HOBAS NC Line was an argument, too. The original idea of the relining sleeve was abandoned and the first 136 m of HOBAS NC Line DN 614/1064 were ordered. The pipes will be delivered at the end of June and installed by a local contractor. Having no experience with these kind of pipes, the contractor was quite sceptical but was finally convinced of HOBAS CC-GRP Pipe Systems. Additionally, HOBAS provided the trolley required to transport the new pipes into the old pipeline.
