The successful project of reference to the approval of DIBt will be discussed. It concerns on Alphaliner DN1500 liner installation (wall thickness of 15 mm) using the new REE4000 UV curing technology.
The UV cured liners will be used in the future frequently also in very large dimensions pipes. A few years ago diameters above DN1200 were reckoned as the upper limit for this renovation technology. Today producers offer size to DN1500 and above.
The RELINEEUROPE company, systems supplier, developed the concept of the large diameters pipes renovation. In the future, will produce liners in diameters up to DN1800.
